Parsa Data
Parsa (EH3, S3) fell April 14, 1942 in the Muzaffarpur district, Bihar, India.
Of ~800 grams recovered, the AMNH has four polished thin sections, and two very small (0.07, 0.09 g)
pieces. Mineralogy and petrology were investigated at the AMNH and described by
Nehru et al. (1984, LPSC 15, p.597), and Prinz et al. (1984, LPSC 15, p.653) at the AMNH, and oxygen
isotopic analysis reported by R.N. Clayton et al. (1984, LPSC 15, p.172). Minor element analytical work icnludes Hewins et al. (1994, LPSC 25, p.543) on Si-bearing metal in chondrules, and Weisberg et al. (1994, Meteoritics 29: 362), on the pyroxene and enstatite
Index (links) for thin section maps:
PTS4549-1: Polished thin section AMNH 4549-1.
Mg-Ca-Al=RGB: A composite x-ray map
(red-green-blue, RGB) where the channels are: Mg=red, Ca=green, Al=blue. (150 dpi, RGB)
element maps: Raw element x-ray mosaics. The x-ray maps for each
element have each been normalized to the same grayscale range to appear as seamless as possible.
These maps are all registered exactly the same, so they overlap perfectly.
Interested viewers can aply their own, preferred color scheme to make RGB composites.
RGB tif files: Raw element x-ray mosaic RGB composites. For each file,
the elements in RGB channels are listed in order (e.g., SiCaNi, NiS-Fe).
