hematite 
anhydrous iron sesquioxid, or red oxid of iron, 
s. It crystallizes in the rhombohcdral system, and 
occurs in iron-black crystals with brilliant metallic luster 
commonly it is massive, with structure varying from com- 
pact to foliated and micaceous (iron-mica or mi 
iron ore), also to columnar and fibrous, and further to 
earthy (red ocker) and impure argillaceous (ironstone) 
kinds. All varieties have a red streak. It is one of the 
most valuable ores of iron, and is mined in large quanti- 
ties, as in the Marquette region of Lake Superior. It is 
sometimes called bloodstone and olifiiste iron (fer oligitte); 
also often red hematite, to distinguish it from the related 
hydrated ore, brown hematite, or limonite, which has a 
brown streak. See cut under ren\form.
