Title: The Tambakwatu chondrite
Authors: Fredriksson, K.; Miller, J.; Nelen, J.; Darsa, S.

The texture and mineralogy of a meteorite that fell to earth on February 14, 1975, near the village of Tambakwatu (Indonesia) are analyzed. Modal analysis by point counting one thin section (a total of approximately 1 sq cm) shows that Tambakwatu is about 87 wt % silicates, 8 wt % metal, 4.5 wt % troilite, and 0.5 wt % chromite. It is noted that the chondrules, most of which are barred or porphyritic, are generally fragmented with barely distinguishable boundaries. A table giving the composition of the meteorite is included. On the basis of classical nomenclature, Tabakwatu is defined as a veined, intermediate hypersthene chondrite (Cia). According to the classification scheme proposed by Van Schmus and Wood (1967), the meteorite is an L6 chondrite.
