Ordinary chondrite, veined (L6; S3)
Fell, 6 April 1914, 7:00 hrs; 45.4 kg, shower
After detonations, a shower of stones fell over 4 villages. The largest stone (32.2 kg) fell in Kuttippuram. Variegated clasts and chondrules (and smaller Fe-Ni grains) are scattered throughout an unevenly textured, but largely equilibrated matrix. Chondrules are frequently indistinct and in various stages of recrystallization. Compositionally and texturally, total iron contents (23.1 wt%Fe), olivine (Fa24.3) and low Ca-orthopyroxene ('hypersthene') are characteristic of L6 ordinary chondrites.
Mineralogically the meteorite consists primarily of dominant olivine and orthopyroxene accompanied by minor plagioclase, troilite, and Fe-Ni metal. Accessory chromite, copper, ilmenite, and other minor sulfides are reported as well. Shock indicators include veins, glass, deformed plagioclase, fractured olivine grains w. undulose extinction, and numerous tiny clasts of melt-rock.
A helium [Pb,Th:He] gas release age of 2.34 Ga may record one or more major post-formational collisional events.
The L-group of ordinary chondrites (relatively low in total iron) are the largest group of classified witnessed meteorite falls and account for ~45% of all well-classified meteorite falls. The L6 petrologic type accounts for ~ 70% of the group. 272 meteorite falls had been classified exactly as 'L6' chondrites by early June 2017. Kuttippuram is the 22nd most massive of the 272 witnessed meteorite falls currently classified exactly as an 'L6' chondrite (June 2017). Bruderheim, a Canadian fall, is the most massive L6 (200 kg).
The main mass has been kept at the Geological Survey of India in Calcutta. A ~400 g mass has been held at the Museum d'Histoire Naturelle in Paris with several very small fragments elsewhere.
