Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.
Shale: Shale breaks into thin pieces with sharp edges. It occurs in a wide range of colors that include red, brown, green, gray, and black. It is the most common sedimentary rock and is found in sedimentary basins worldwide.
Mar 26, 2018· To identify gold inside of a piece of quartz, hold a magnet against the rock. If the quartz sticks to the magnet, then it contains iron pyrite, or fool’s gold. You can also try to scratch a piece of glass or unglazed ceramic with the gold portion of the rock. Real gold will not scratch these substances.

Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scaly-foot gastropods. Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold.
The Cretaceous Mancos Shale of eastern Utah (Fig. 1). covers several thousand square miles. It is a thick, homogenous, organic-rich shale, and like many black shales is enriched in metals. Persistent rumors of high grade gold mineralization throughout the
Look for gold and gold-containing quartz rocks in areas where volcanic hydrothermal activity has taken place in the geologic past. These areas include the regions around old gold mines and rock outcrops upstream from placer gold deposits where gold has eroded out of its bedrock, washed downstream and accumulated in and near stream channels.

May 25, 2019· Decide the best name for its color or colors, such as blue-green, sky blue, lilac, indigo, violet, or purple. This is more difficult to do with translucent minerals than with opaque minerals. Next, note the mineral's hardness and its luster on a freshly cut surface. Finally, determine the rock class (igneous, sedimentary, or metamorphic).
Apr 19, 2018· An opaque, lustrous mineral that forms natural crystals with flat facets or that has large smooth surfaces. Some examples are: Chalcopyrite, a lustrous metallic crystalline mineral Molybdenite, lustrous metallic crystal Obsidian, a shiny,
Apr 10, 2017· Shale is a clay-rich sedimentary rock found all over the world. If shale gets wet, it usually smells like mud or wet dirt. However, the rock known as oil shale has a smell like diesel oil or tar. That oily smell is from a petroleum-like substance known as kerogen. Kerogen is not yet oil.
One example is Old Rag Granite, which forms some of the mountainous peaks of Shenandoah National Park in the Blue Ridge Province, including Old Rag Mountain. Slate Slate is a metamorphic equivalent of shale. The clevage in slate formed when the argillaceous (clayey) rock shale is subjected to heat & pressure during mountain building.
Shale fragmental SHALE is a very common rock made of silt and clay sized particles. It is generally very thin-bedded and splits along the bedding planes. In fact, the name is probably from the Old English scealu, “shell or husk”. Normally gray to black, shale may be brown to dark red, depending on the amount of included iron oxide.
