Carbonaceous Chondrite, CM2
24 May 1933; 629 g, 4 stones

After an afternoon fall, 4 stones were recovered. Examinations have revealed a complex melange of minerals and phases complete with chondrules, individual grains, glass fragments, inclusions, xenoliths, and other diverse components characteristic of the CM (Mighei-like) Carbonaceous Chondrites. Banten, however, may be a little different in more obviously displaying its preterrestrial hydrated and water-soluble phases (phyllosilicates, carbonates, sulfates …). Mg-rich olivine and pyroxenes are prominent but opaques and hydrates with minor Fe-Ni metal are present both in mineralogically identifiable form as well as in small, poorly characterized phases. In addition to the oxygen-isotope ratios which serve to define the various groups of Carbonaceous Chondrites, Banten includes 'heavy' Carbon-13 isotopic ratios presumably derived from the formation epoch. A cosmic ray exposure age (~4.5 Ma) suggests a brief time as a small meteoroid before its impact with the earth.

Banten is the 7th of the 15 CM witnessed falls recorded between 1838 and 2009. Of only moderate mass, it is still the 7th most massive of the listed CM falls. The CM Carbonaceous Chondrite Group is the most numerous of the 8 chemically defined Carbonaceous Chondrite Groups with nearly 500 CM meteorites or meteorite fragments reported on the Meteoritical Society's 'Meteoritical Bulletin Database' by early 2015. However, the great majority of these meteorites are very small Antarctic finds and presumably represent a much smaller number of individual falls which were fragmented both during entry and then while transported under the slowly moving ice before eventual recovery.
