Working in the field, you encounter a metamorphic rock that lacks foliation and is composed primarily of interlocking sand-sized grains that will scratch glass. How should this rock be classified? Water migrates into host rock carrying ions to stable minerals in order to facilitate growth of new metamorphic minerals.
Gold is always more or less intimately associated with quartz. Oxide of tin is said never to have been found more than two miles from some granite rock, one of the components of which was muscovite or white mica. The junction of slates and schists with igneous or metamorphic rocks often proves a valuable find of mineral.
Gold mines were active before World War II, extracting from crystalline basement rock in the northwest, but a combination of low gold prices and legal turmoil ended the industry. The Younger Granites of the Jos Plateau contain significant tin deposits, mined since before European colonization.
I've found gold in conglomerate/cemented rock before, and there are deposits of gold in sedimentary rock as well. However, the odds are lower, as others have stated. They are hosted in metamorphic rocks. These sediments (with some volcanics) were changed by the heat and pressure of plate collisions and burial while being accreted. Its that
Schist As a Gem Material Host Rock. Schist is often the host rock for a variety of gemstones that form in metamorphic rocks. Gem-quality garnet, kyanite, tanzanite, emerald, andalusite, sphene, sapphire, ruby, scapolite, iolite, chrysoberyl and many other gem materials are found in schist.

"In practical terms, what this means is that in areas like this, gold deposits might be more common and/or bigger than they would have been if the rocks were not plume-derived," said Alex Webber

A few areas in the United States are well-known for their geodes and geode-like objects. Geodes are so popular in a few states that they have achieved the status of “official state rock” or “official state gem.” The Iowa State General Assembly designated the “quartz geode” as the official “state rock” in 1967.
Apr 24, 2017· Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

Cooling water seeping through the metamorphic rocks hardens the gold, resulting in ore deposits that run through sedimentary rocks as veins. Lode deposits are found in old rocks, older than 2.5 billion years, belonging to the Archanean geologic period and near sea floor volcanoes.

potential in the state for important discoveries of gold reserves, as well as other metals. This belt is defined by metamorphic rocks, many of which were originally deposited as “volcanics,” which could have been, in part, endowed with gold. The most intensive placer-recovery gold activity in
The green tsavorite has a bright, rich green color which is akin to that of the emerald. However, the greens cost a good bit more than the reds but the tsavorite makes a good alternative stone to emerald. Garnet in Metamorphic rocks: Most garnet forms at convergent boundaries where shale is being acted upon by regional metamorphism.
- Erosion takes over and removes the upper material exposing deeper rock below Many metamorphic rocks are dry, which prevents retrograde reactions-Large regions of ancient high-grade metamorphic rocks are exposed in continental interiors Called shields, these
Whether you have a general fascination with all aspects of geology or you are seeking specific information about the gold market, it is important to apply due diligence so that you know as much as possible about this precious metal and understand the power of gold as an investment.
Rocks are naturally occurring combinations of two or more minerals. There are three broad categories of rocks—igneous, metamorphic, and sedimentary. An example is Winnsboro Blue Granite an igneous rock composed of the minerals quartz, feldspar and mica that is also the state stone of South Carolina.

An old, and largely discounted process, granitization states that granite is formed in place through extreme metasomatism by fluids bringing in elements, e.g. potassium, and removing others, e.g. calcium, to transform a metamorphic rock into a granite. This was supposed to occur across a migrating front.
