Shale - Wikipedia

Shale is a fine-grained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility. It is the most common sedimentary rock.How to find gold, working slate or shale bedrock. (nugget,,Oct 31, 2018· How to work slate or shale bedrock to find gold.

These carbonaceous rocks commonly occur over many tens of kilometers of rock band inMarcellus Formation - Wikipedia,Description. The Marcellus consists predominantly of black shale and a few limestone beds and concentrations of iron pyrite (Fe S 2) and siderite (FeCO 3). Like most shales, it tends to split easily along the bedding plane, a property known as fissility. Lighter colored shales in the upper portion of the formation tend to split into small thin-edged fragments after exposure.

Shale Rock: Geology, Composition, Uses

Aug 02, 2020· Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.Mineral Commodity Report 14 - Gold,Gold mining languished during the Middle Ages, but was revived in the 1200s, following,finely divided it may be black, ruby or purple.
