Banded iron formations, pyritic black shale, and gold ,The occurence of gold in sandstones and shale - GPEX

Banded iron formations (BIF) are predominantly Precambrian sedimentary rocks composed of alternating layers of iron-rich minerals (commonly hematite and magnetite, but also siderite, chlorite, and grunerite) and silica-rich minerals (eg, quartz or chert) in which the Fe content of the entire rock is at least 15 wt % Although typically thought of as strictly Fe resources, such as in the .Apr 23, &#; Gold, Mining and Prospecting: Detrital Gold Deposits this seems like an interesting topic to discuss many people who live in shale and sandstone areas often see rust in pieces of shale where iron oxides have been deposited and formed into the shale.
