Genesis Stone / Banded Iron Genesis Stone / Banded Iron is a sedimentary stone made of alternating layers of jasper and hematite or magnetite. It was formed 1.8 - 2.4 billion years ago in the ancient iron seas. These pieces were broken off from the main formation by an unknown event and left to weather on the Wyoming plains.
Banded Iron Formation. Banded Iron formations occur in Proterozoic rocks, ranging in age from 1.8 to 2.5 billion years old. They are composed of alternating layers of iron-rich material (commonly magnetite) and silica (chert). Each layer is relatively thin, varying in thickness from a millimeter or so up to several centimeters.

Banded Iron Formation (also known as BIF, or as taconite in North America) is a term that is applied to a very unique sedimentary rock of biochemical origin. These rocks are unique in their make up, unique in their age and unique in their origins. They are found all over the world, but only in certain areas of all the major continents.
Banded Iron Formation. Banded iron formation or BIF is a chemical sediment, typically thin-bedded or laminated with >15% iron of sedimentary origin. BIF has a very distinct distribution with time (see Figure 9.32 in Chapter 9). It is found in minor amounts in the early Archean and in large amounts in the late Archean, appears again around 1.9 ...
Most of the major iron deposits worldwide occur in rocks called banded iron formations (or BIFs for short), which are finely layered sedimentary rocks composed of alternating chert (a form of quartz) and iron oxide bands. The banded iron formations of the Hamersley Province in the Pilbara region of Western Australia, are the thickest and most ...

An example of a mineral in iron-rich rock containing carbonates is siderite and an example of minerals in an iron-rich rock containing silicate is chamosite. They are often interbedded with limestones, shales, and fine-grained sandstones. They are typically nonbanded, however they can be very coarsely banded on occasion.
Jan 30, 2011· Virtually all of the iron produced in the world for consumer use is refined from rocks that are high in iron mineral content; banded iron, a type of rock, is the main iron ore.
