LPI Seminar Series
LPI seminars will be held on Thursdays.
LPI seminars are held from 3:30–4:30 p.m. in the Lecture Hall at USRA, 3600 Bay Area Boulevard, Houston, Texas. Refreshments are served at 4:30 p.m. For more information, please contact Georgiana Kramer (phone: 281-486-2141; e-mail: email@example.com) or Patricia Craig (phone: 281-486-2144; e-mail: firstname.lastname@example.org). A map of the Clear Lake area is available here. This schedule is subject to revision.

LPI Seminar: Application of Al-in-Olivine "Astrothermometry" to Extraterrestrial Igneous Systems
Volcanic and plutonic samples are directly linked to the constitution of planetary interiors. Further, igneous materials can preserve the thermal history of large-scale magmatic evolution including primary mantle accumulation, convective styles, hybridization, and source melting. We propose the first application of Al-in-olivine "astrothermometry" to understand the origin of key geochemical signatures observed among martian, lunar, and igneous astromaterials and their relationship to interior sources. In so doing, this work aims to establish chemical connections between the primary mantles of rocky bodies in order to redefine models of planetary differentiation.

LPI Seminar: Disk sub-structures revealed by ALMA: implications for planet formation.
The Atacama Large Millimeter and sub-millimeter Array (ALMA) has discovered sub-structures in the dust and molecular gas distribution a number of protoplanetary disks. These structures span spatial scales from a few to hundreds of Astronomical Units and are thought to be related to the formation of planets. During my talk I will present some of the most recent ALMA observations of sub-structures in disks and discuss them in the framework of planet formation models.
