Writeup from MB 105:
Mount Blanco 33°45.37644’N, 101°14.9367’W Texas, USA Confirmed fall: 18 Feb 2016 Classification: Ordinary chondrite (L5) History: On the night of February 18, 2016, the American Meteorite Society received numerous reports from Texas, Kansas, Oklahoma, and New Mexico of a fireball. The probable location of this fall was identified by Robert Ward and Dr. Marc Fries using radar data. One stone was discovered in a cotton field by Terry Scott and Sonny Clary on February 22. Physical characteristics: Single stone of 36.2 g, almost fully fusion-crusted. A cut surface revealed a light-gray interior with abundant metal and a few clearly distinguished chondrules. Petrography: (R.G. Mayne, TCU). The thin section used for classification of this meteorite contains one barred olivine (BO) chondrule with sharp boundaries but the remaining chondrules, although they can be discerned, do not show similar sharp boundaries and in some cases are poorly delineated. The matrix is recrystallized and chondrule glass appears devitrified. Feldspar grains within the section vary in size but are less than 50 μm. Geochemistry: (C. Agee, UNM) Average compositions are as follows, olivine (N=6) Fa24.8±0.1, pyroxene (N=7) Fs20.8±0.2 Wo1.4±0.3. Classification: Ordinary Chondrite (L5); the sample is a freshly collected fall (W0). Specimens: 8.4 g TCU; main mass of 26.8 g shared by Clary and Terry Scott/landowner. | ||||||||||||||||||||||||||||||||||||
