This is a stony iron meteorite composed of iron and other elements, namely Ni, Si, P, Ti and S. This was a large meteorite fall partially descripbed below from Mindat. In all probability the green minerals shown here (light greenish yellow for Paraotwayite and darker green is Retgersite) are from wearthering here on Earth. On the sawed surface grains of silvery iron flashes can be seen.

It is more than 4 times as massive as the second most massive mesosiderite, Bondoc, an 888.6 kg mass recovered from the Philippines in 1956. Several pieces up to 25 kg in mass were found in the late 19th century. A large strewnfield (11.5 km x 2.1 km)"
