Carbonaceous chondrite (CM2)
Fell, 22 Jun 1940; 113 g

Erakot is a rare CM (Mighei-like) Carbonaceous Chondrite and, as such, is referred to in numerous articles. It apparently is rich in phyllosilicates, aqueous alterations products and various inclusions, but specific mineralogical references are rather sparse for this small meteorite. Only 15 CM chondrite falls had been discovered by early 2015.

CM Chondrites are the most numerous group of carbonaceous chondrites with 500 CM meteorites or meteorite fragments now recovered. However, most of them are small Antarctic finds and may represent a significantly smaller number of individual falls.

The main mass is held at the Geological Survey of India (Calcutta).
