You are cordially invited to participate in the international conference on Catastrophic Events and Mass Extinctions: Impacts and Beyond, to be held at the University of Vienna, Austria, from Sunday, July 9, 2000, to Wednesday, July 12, 2000. The meeting will start with registration and a welcome party on Sunday, July 9, 2000, at the Geological Survey of Austria, Rasumofskygasse 23, A-1030 Vienna. Oral and poster sessions will be held Monday to Wednesday (July 10-12, 2000) at the "Geozentrum" (UZA II) of the University of Vienna, Althanstrasse 14, 1090 Vienna. Detailed directions to both locations will be included in the final announcement. In a slight change to the information given in the first announcement, we are now offering two pre- and two postconference field trips, to allow participants to join two different field trips if they so desire (see
Field Excursions below).

Vienna is the capital of the Federal Republic of Austria, a member of the European Community. With about 2 million people in the Vienna metropolitan area (out of about 8 million in Austria), it is one of Europe's most historical and beautiful cities. Palaces, museums, gardens, coffee shops, wine taverns (the famous "Heurigen"), and abundant musical events offer entertainment and relaxation (preferably before and after the conference!). The weather in July should be pleasant, warm (about 20-30 degrees Celsius, or 68-85 degrees Fahrenheit), and mostly sunny, but occasional cold spells and rainy periods are possible. Public transportation is inexpensive and efficient. Vienna is easily reachable by airplane, train, or car.

For detailed information on Vienna, including cultural programs, museums, concerts, public transportation, maps, addresses, and other links, see the Web page of the Vienna Tourist Board ( For general information on Austria, see the Web page of the Austrian National Tourist Office (

This conference will be the fourth of an informal series of meetings on mass extinctions and global catastrophes, including the geological and biological consequences of large-scale impact events. The first and second of these meetings were held in 1981 (October 19-22) and 1988 (October 20-23) at Snowbird, Utah, and the third one took place in 1994 (February 9-12) in Houston, Texas. The first of these meetings dealt mainly with the then-controversial hypothesis that a large-scale impact event occurred 65 m.y. ago and was responsible for the end-Cretaceous mass extinction; the second meeting focused on the evidence (e.g., in terms of shock metamorphism) that such a large impact event happened; and at the third conference the discussion centered on the Chicxulub impact structure, which had in the meantime been proposed as the long-sought K/T boundary impact crater.

We are now at a stage where the question should be asked if (and how) short-term, high-energy events influence biological evolution on the Earth. Various mass extinctions, of different degrees, mark some of the geological boundaries. These have been studied in the past, but only recently has there been a discussion on how short the timescale of these mass extinctions really was. For example, recent studies of the most profound extinction event in Earth's history, at the end of the Permian, indicated a much shorter time frame for this event than earlier data had suggested, with significant associated geochemical anomalies. The cause for this global catastrophe is currently unknown. Other short-term events (e.g., Proterozoic Snowball Earth, late Devonian, Triassic-Jurassic, late Eocene) in the stratigraphic record of the Earth are now receiving unprecedented attention. Thus we feel that the time has come to summarize and discuss the current state of knowledge of the character and causes of mass extinctions and catastrophic events in the history of our planet.

The venue for the scientific sessions will be the new "Geozentrum" (UZA II) of the University of Vienna at Althanstrasse 14 in Vienna's 9th district. This building houses all Earth science institutes of the University of Vienna, as well as a library and various lecture halls. Oral and poster sessions will be held from Monday, July 10, to Wednesday, July 12, 2000. Registration will be available throughout the meeting. No parallel sessions are planned. Oral sessions will be held from 8.30-12.30 and from 14.00-18.00, with a half-hour coffee break during each session. A poster session (with refreshments) will be held next to the lecture hall on Monday afternoon (July 10, 2000). Posters will remain on display throughout the entire meeting. A public lecture broadly related to the topic of the meeting is planned.

To maximize interaction among all participants, allow for ample discussion time, and emphasize the interdisciplinary nature of this meeting, all contributions will be considered (similar to previous meetings of this series) for poster presentations. Oral presentations will consist of 25-minute invited reviews intended to set the stage for certain topics selected by the international program committee, and some 5-minute presentations selected by the program committee from all other contributions. The latter are intended to supplement review talks on specific topics and provide either new and important data, viewpoints, arguments, or present a controversial viewpoint. Discussion time will be scheduled to amount to approximately 50% of the total time available. Also, to allow efficient interaction and discussion, attendance will be limited to 300 participants (the maximum capacity of the lecture hall).

Projection equipment available for oral presentations will consist of two 35-mm slide projectors and two overhead projectors. Should video projection be required (PAL and NTSC formats only), please contact the local organizers before the meeting. No computer or video facilities are available for poster presentations; however, if presenters are bringing their own equipment (e.g., a laptop computer), please contact the local organizers well before the meeting for space and power requirements. Return to Table of Contents

As with the previous three meetings in this series, a proceedings volume will be published as a Special Paper by the Geological Society of America (GSA). Deadline for receipt of manuscripts is October 1, 2000. We are currently conferring with GSA to ensure speedy publication of the volume. Details for manuscript preparation and submission will be available with the final announcement and at the meeting.
Return to Table of Contents

Researchers in scientific disciplines related to any aspect of the meeting are invited to contribute abstracts for poster presentation (print-only abstracts will not be considered). As explained above, the program committee will select some of these abstracts for five-minute oral presentations. Abstracts may not exceed TWO pages, including graphics, tables, and references. All abstracts must include FULL mailing addresses of all authors. Possible topics include, but are not necessarily limited to, the following:

  Crises in Earth history
         Proterozoic Snowball Earth
         Late Devonian extinctions
         Permian-Triassic boundary
         Triassic-Jurassic boundary
         Jurassic-Cretaceous boundary
         Cretaceous-Tertiary boundary
         other boundary events
  Environmental consequences of impacts and other short-term, high-energy events (e.g., volcanism)
  Mechanisms of mass extinctions: causes and relations
  Atmospheric response to impacts, volcanic eruptions, glaciations
  Connection between impacts and volcanism
  Interpretation of the stratigraphic record:  reading event markers, determination of near-extinctions, recognition of a hiatus, discussion of "true" blind tests
  Extraterrestrial influences:  near-Earth asteroids, comets, companion stars, supernovae, etc.
  Large-scale impact events in Earth history

Abstracts on related topics not listed here are also welcome. However, contributions should be relevant to the general theme of the meeting; thus papers dealing with, e.g., details of a particular impact crater, or local biostratigraphy, may not be considered. Contributors are also asked to indicate whether they regard their work as primarily new data, new data with significant implications, a model or new interpretation of data, or a review.

The abstracts and preliminary program will be available on line on or around April 7, 2000. They will be posted in PDF format, viewable with version 3.0 or higher of the Adobe Acrobat Reader, which can be downloaded free of charge from the Adobe home page.

The 15-m.y.-old, 24-km-diameter Ries Crater is one of the best-studied impact structures in the world and is the largest and best-exposed one in central Europe. Nordlingen has an excellent museum with displays covering the complete geological and biological history of the Ries, from impact to today. Outcrops showing a variety of impact-related rocks will be visited. On the return trip to Vienna, we will visit the well-known Kendelbachgraben TR-J boundary section in Upper Austria. Participants will have a chance to take samples. If time and weather permits, a visit to the Gosau K/T boundary section is possible.


Wednesday, July 5
8.00:  Bus leaves from Geozentrum (University of Vienna) in Vienna; drive to Nordlingen (southern Germany), arrival between 14.00 and 15.00, check into rooms.
17.00:  Reception at the Riescrater-Museum and guided tour of the museum
19.30:  Joint dinner

Thursday, July 6
Departure:  parking lot Kaiserwiese at 8.00
Stop No. 1:  Wallerstein cliff (lacustrine limestone):   Panorama view across the crater

The Wallerstein cliff is located at the center of Wallerstein, a small village 4-5 km northwest of Nordlingen. It offers a nice panoramic view across the crater from the top at an elevation of 495 m above sea level. The cliff juts out about 75 m from the present-day basin plane. Under clear weather conditions various morphological aspects of the crater can be seen.

Stop No. 2:  Wengenhausen quarry (shocked crystalline basement rocks, lacustrine limestone).

The quarry (not in operation) is located 7 km northwest of Nordlingen, close to National Road B 25 (the road from Nordlingen to Dinkelsbuhl). Two different types of rocks are exposed:

(1)  Strongly shocked and weathered rocks of the crystalline basement (gneisses, amphibolites, granites). Dyke rocks occur in the form of so-called "Flecken-Kersantit" (kersantite). Evidence of impact also comes from the occurence of shatter cones in these dyke rocks.

(2)  The ejected basement material is partly overlain by a thin layer of limestone.

Stop No. 3:  Aumuhle quarry (fallout-suevite overlying Bunte Breccia) is located at the northern rim of the crater 2.5 km north-northeast of the city of Oettingen and is an operting quarry (suevite is used as an additive for cement production).
Stop No. 4:  Polsingen quarry (impact melt breccia) is a small old quarry no longer in operation in the so-called "red-suevite" near the village of Polsingen, some 5 km northwest of Wemding.

Lunch at the "Gasthaus Wallfahrt" 12.30-14.00

Stop No. 5:  Otting quarry (fallout suevite, Bunte Breccia). This suevite quarry is currently out of operation, and is located northwest of the village of Otting, approximately 5 km east of Wemding and the crater rim (distance to Nordlingen 25 km).
Stop No. 6:  Gundelsheim:  autochthonous Upper Jurassic limestone with a polished and striated surface, overlain by Bunte Breccia. The outcrop (Teich quarry) of Malm Delta limestone with Bunte Breccia on top is situated to the east-northeast of the Ries Crater, about 7.5 km from the crater rim and 21.5 km from the crater center.
Stop No. 7:  Gosheim outcrop: dislocated and overturned malmian limestone block; the exposure is situated at the inner slope of the eastern crater rim near the village of Gosheim.
Stop No. 8:  Wennenberg (old basement quarry):  The Wennenberg is located 10 km east of Nordlingen as a cone-shaped hill, partly covered by forest. It belongs to the inner crystalline ring with a continuous contact to the basement.

Friday, July 7
Departure:  parking lot Kaiserwiese at 8.00
Steinheim Basin:  This basin represents a complex impact crater 3.4 km in diameter with a well-developed central uplift (Klosterberg-Steinhirt). The age of this event was determined by paleontological methods to be coeval with the Ries Crater.

12.00:  Arrival at Nordlingen

12.00-13.30:  Lunch

13.30-15.00:  guided tour of the city of Nordlingen (e.g., St. Georg, the "suevite" church)

Saturday, July 8
8.00:  Departure from Bad Ischl to Strobl and on to Kendelbachgraben; visit of the Kendelbachgraben TR-J boundary section with sampling opportunity. If time and weather permits it might be possible to visit the Gosau K/T boundary section in the afternoon. Departure to Vienna around 16.30. Arrival in Vienna about 20.00.


2.  K/T Field trip:  Black Sea, Bulgaria (BJALA)

Duration:  July 6-9, 2000 (from/to Varna, Bulgaria)
Cost:  4200.- ATS
Included:  travel by bus in Bulgaria (to/from Varna airport), all meals, and accommodation (based on double occupancy) at the Hotel Villa Sagona, Varna (spacious double and single rooms); excursion guide.
Not Included:  airfare from Vienna to Sofia-Varna and return (see below); personal expenses, drinks, single room supplement: 300.- ATS.
Participants:  minimum 10, maximum 20

Field trip leaders:

Anton Preisinger (Technical University of Vienna, [email protected])
Herbert Summesberger (Natural History Museum, Vienna, [email protected])
Selma Aslanian (Bulgarian Academy of Sciences, Varna, Bulgaria)

Summary:  In 1991 the first K/T boundary section in hemipelagic marine sediments was discovered in Bulgaria on the coast of the Black Sea near the city of Bjala, 35 km south of Varna. This K/T boundary section is located in the Luda Kamchiya unit, lying between the Balkan chain in the south and the Moesian platform in the north. A spectacular rhythmic sedimentation over a vertical range of a 100 m resulted in the deposition of limestone with intercalated marl. Two hundred limestone beds correspond to precessional Milankovitch cycles. A 5-m.y. absolute geological timescale results from the combination with the measured magnetic polarity changes (Chron 29R to Chron 26R). The reference age (65.0 Ma) corresponds to the level of the maximum iridium content in the K/T boundary. Evidence for Maastrichtian age is given by macro-, micro-, and nannofossils. The evidence of Palaeogene age is given by micro- and nannofossils. In the Bjala section three post-K/T event markers can be distinguished:  fall-out, boundary clay, and reworked Cretaceous sediments.

Note:  A group flight can be organized from Vienna via Sofia to Varna on Thursday, July 6, and from Varna via Sofia to Vienna on Sunday, July 9, 2000. Arrival in Vienna on July 9 will be before 16.00 to allow registration and participation in the welcome party. Cost: approximately 5000.- ATS. It is highly recommended that you join this group flight to facilitate the organization of the field trip and allow you to obtain a group rate. Please indicate on the form if you want to be part of the group or if you will make your own air travel arrangements (give details of your reservations).
