Enstatite Chondrite, high-iron [EH3.5; S3]
Fall, 14 April 1942, 800 g; weathered

Two stones (masses ~600 g, ~200 g) fell on opposite sides of the Gandak River. They were not fully described and classified, however, until the 1970’s. Both stones are Enstatite Chondrites, but the larger stone also contains a large semi-exotic clast labeled as an ‘Aubrite basalt vitrophyre (ABV)’. Unfortunately, for reasons not completely understood, Parsa also shows signs of unanticipated weathering (e.g., Fe-oxides) not normally seen in observed falls.

The Enstatite Chondrite Class is defined by specific elemental ratios and by earthlike oxygen isotopic ratios. Mineralogically, Enstatite Chondrites are characterized by the presence of dominant iron-poor Enstatite, accessory Fe-Ni metal, and a number of very reduced mineral phases (sulfides, nitrides, silicides). Many of these phases are either unknown or very rare in terrestrial rocks. The EH (high iron) chemical group is further characterized by abundant iron (~10-20 vol%) and the minerals niningerite and perryite. Parsa’s EH3.5 petrologic type indicates that Parsa’s abundant chondrules and matrix have been incompletely equilibrated by mild metamorphism. In addition, Parsa’s S3 shock level indicates moderately strong pre-terrestrial shock.

In 1989 Klaus Keil proffered a number of persuasive arguments suggesting separate parent bodies for EH Chondrites, EL Chondrites, Aubrites, and the unusual Shallowater meteorite. However, Parsa’s somewhat mixed mineralogical population is not easily explained with such a clean separation of the Enstatite-rich meteorite homeworlds.
