Jan 06, 2009· The best known are hematite and pyrite, two iron-based minerals that are often used for ornamental purposes. Hematite is iron oxide that gets its name from the Greek word for blood, since it is red when sliced thinly or powdered. Hematite forms in the rhombohedral crystal system, which is the same crystal structure as sapphire and ruby.
The 3.46 Ga Marble Bar Chert/Jasper unit in the Pilbara district, W.A. was probably deposited in a deep (>500 m) ocean during the accumulation of a thick (>5 km) submarine basalt. Debate focuses on whether organic matter in pre-2.0 Ga cherts is a remnant of marine organisms or the product of abiotic synthesis in hydrothermal systems, whether the hematite crystals in jaspers were primary or ...
Magnetite, Fe3O4 is produced abiotically and biotically. Abiotically, magnetite is a late magmatic mineral and forms as a consequence of the cooling of iron rich magma. Biotically, magnetite is produced by several organisms, including magnetotactic bacteria. Hematite, Fe2O3, is also produced abiotically and biotically. Abiotically, hematite rarely occurs as a primary mineral in igneous rocks ...
