Kolkata - Primary analysis of the fragments of the cosmic fireball
that fell over large stretches of Orissa's Kendrapada and Mayurbhanj
districts on September 27 showed that it was an iron meteorite,
heavier than its stony version.

Based on accounts of scientists studying the fragments at GSI,
Bhubaneswar, Basab Chattopadhyay, Senior Geologist of GSI's
Central Petrological Laboratories at its headquartes in Kolkata
said, the meteorite was heavier due to iron content as opposed
to stony meteorites.

"Generally meteorites are classified either as iron or stony
meteorites based on their contents. The fragments obtained
from Orissa have been found to have iron content and as such
their specific gravity is greater," he said.

The stony meteorites have a specific gravity of 3.84 as against
iron meteorites which have a specific gravity of 7.8,
Chattopadhyay explained.

He said the fragments would be transferred to the Kolkata
laboratory by Tuesday and confirmatory tests to verify its age,
density, type and rarity would be made here as well as at the
Physical Research Laboratory (PRL), Ahmedabad.

The remnants of the meteorite weighing 5.7 kg and 500 grams
received from Purba Suniti and Paschima Suniti villages of
Kendrapada district would later be handed over to the Indian
Museum.
