Putorana Native Iron 	
Krasnoyarsky Kray, Norilsk, Russia
A meteorite (mesosiderite) looking like rock from Siberia is not a meteorite. But this type of rock is really rare on the Earth. 
Usually Iron is occurring as oxidated like Magnetite, Hematite, Goetite, Limonite etc, but here we have a unique case of native 
not oxidated Earth Iron. Iron at this locality occurs in basalt sills that have intruded coal beds. The coal had acted as a reducing 
agent effectively "smelting" the iron in the basalt liquid. The Putorana rock is an annealed breccia of basaltic clasts in a matrix of 
basaltic and metallic minerals. The rocks exterior is weathered and rusted, without obvious fusion crust. 
The interior is essentially unweathered. Breccia fragments include basalt of several textures, fine-grained anorthosite, 
and feldspathic dunite. Nonmetallic minerals are: Plagioclase, Pigeonite, Olivine and rare Ilmenite. 
Metallic grains compose about 50% of the matrix. The cores of these grains are 
Fe-Ni metal with exsolution lamellae and blebs of Cu-rich metal. The cores are surrounded by cohenite, Fe-carbide.
The deposit of these rocks is in area of the upper reaches of the river Kureika on the Plateau Putorana, 
north of Krasnoyarsky Kray not so far from Norilsk city, Russia.
