Writeup from MB 82:
San Borjita Corrientes Province, Argentina Found and possibly fell 1983 November Ordinary chondrite (L4) A 12.3 kg stone was found by Mr. Don Torres and an unidentified truck driver shortly (perhaps a few days) after witnessing a large fireball. However, the moderately weathered condition of the stone casts a degree of doubt on whether the recovered meteorite actually fell in the 1983 event. Classification and mineralogy (T. McCoy and S. Russell, SI): olivine, Fa24.4; pyroxene Fs19.8Wo0.8; shock stage S3; weathering grade W2. Specimens: main mass with Mr. Alejandro Marin of Posadas, Argentina; one fragment possibly retained by truck driver; type specimen, 14.4 g, SI. | ||||||||||||||||
