Taqtaq-e Rasoul        34° 36' 56"N,  45° 46' 8"E

Bakhtaran, Iran

Confirmed fall: 2019

Classification: Ordinary chondrite (H5)

History: Around 07h50 local time (GMT+3.5) on 10 August 2019, residents of several villages in Dasht-e Zahab region of Kermanshah province in Iran heard loud explosions like thunder. They were followed by noises similar to flying drones. Moments later, Madam Gohari a resident of Taqtaq-e Rasoul village (next to a hill with a similar name) noticed an object fall in their family yard, producing dust and getting dogs excited, surrounding it. After receiving a call from his mother about the event, Saman Gohari arrived at the site after 20 '. Informed about meteorites, he collected the stone (claiming that the stone was still hot). Because of site’s vicinity to Iraq’s border (~4 km), police investigated the site and the rock was broken into several pieces (two main pieces). As the area close to the border is covered by land mines, searching for more fragments was not possible. Several search attempts in the farms around the house and the villages failed to find additional fragments. A ~30 g fragment, along with several small fragments (~14 g together) were sent to Hamed Pourkhorsandi for study.

Physical characteristics: Originally a single stone was covered with fusion crust. A layer of soil was visible on the surface, resulting from its impact with the ground. Light-gray interior hosts chondrules. Metal and sulfide grains are visible by naked eye.

Petrography: Chondrite with recrystallized texture. Plagioclase average size is 40 µm. Opaque minerals are Fe,Ni metal and troilite.

Geochemistry: Olivine Fa19.1±0.3 (n=5), orthopyroxene Fs17.0±0.1Wo1.3±0.1 (n=4), plagioclase An12.2Ab83.4Or4.4 (n=1).

Classification: Ordinary chondrite (H5) based on petrography, magnetic susceptibility and mineral chemistry.

Specimens: A piece of ~1050 g is with the finders, ~650 g is with the police, and ~260 g is in Hojat Kamali’s private collection. Type specimen (30 g) and a polished section at CEREGE. 14 g at RBINS.
