Structures in the banded iron

banded magnetite quartzite encloses a lowland occupied by metabasic rocks The magnetite quartzite generally dips inwards, and as a result the hills present steep slopes and formidable scarps, up to 100 metres high, at the outer side and gentle dip slopes at the inner side...

Magnetite

Magnetite (Fe 3 O 4) is a common iron oxide mineralIt is a member of the spinel group These are minerals that share the same structure but differ in chemical composition Other notable members of the group are chromite and spinelMagnetite is among the two major sources of iron...

1 IRON ORE DEPOSITS OF INDIA

Banded Magnetite Jasper(BMJ) , Banded Martite Quartzite (BMtQ) refers to rocks composed of regular alternate layers of iron oxide essentially in the form of martitized magnetite with or without supergene/secondary hematite and silica in recrystallized form , All the iron ore deposits of India belong to the Iron ore series and...

Banded iron formation

A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor shales and cherts, often red in color, of similar thickness, and containing microbands (sub-millimeter) of iron oxid...

Geochemistry and origin of Archean banded iron

Oxide and mixed oxide-silicate-carbonate facies banded iron-formation of the Bababudan schist belt are metamorphosed to a lower amphibolite faci A wide spectrum of minerals including quartz, magnetite, grunerite, biotite, ankerite, siderite, and calcite is responsible for variation in major element composition...

Magnetite

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself It is the most magnetic of all the naturally-occurring minerals on Earth Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ....
