and D as well as their subclusters, represented as dark blue circles, are composed of different numbers of samples and contain different amounts of core (i.e., present in all first level groupings), exclusive (i.e., occurrence restricted to first level grouping) and neutral (others) gener...
The Zenith mine, at Ely in the Vermilion iron district of Minnesota,yielded about 21 million tons of high grade iron ore before closing in 1962. Theore that was mined consisted of massive crystalline hematite, brecciated andcemented by a later generation of crystalline hematite. The deposits are...
The Middle-Lower Yangtze metallogenic belt is a intra-continental belt dominated by Yanshannian magmatic mineralization.There are two types of iron ore deposits in this area: one occurs mainly in volcanic-sedimentary basin and is genetically related to the intrusion of intermediate to mafic magma and...

,Singh,and,Rajeev 摘要: Several small Mn–Fe oxide and Mn-oxide ore bodies associated with Precambrian Iron Ore Group of rocks are located within Koira-Noamundi province of north Orissa, India. These deposits are classified into in situ (stratiform), remobilized (stratabound) and reworked ...
Fission and alpha-particle emission would then make heavy nuclei decay into iron, converting all stellar-mass objects to cold spheres of pure iron.[27] Origin and occurrence in nature Cosmogenesis Iron's abundance in rocky planets like Earth is due to its abundant production during the runaway...
