Met Bull write-up :
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.
