Schist has medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel). It is defined by having more than 50% platy and elongated minerals (such as micas or talc), often finely interleaved with quartz and feldspar.

There are two main types of metamorphism:

• Contact metamorphism—occurs when magma contacts a rock, changing it by extreme heat (Figure 4.14).
• Regional metamorphism—occurs when great masses of rock change over a wide area due to pressure exerted on rocks at plate boundaries.

The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8).

Large-grained schists include Magma Gold, Asterix, Saturnia, and Kosmus.

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.

Yes you can find gold in rivers that have mica but it will not be on top. Gold is one of the heaviest things in the river. Mica is really a whole host of minerals, muscovite, biotite and chlorite being the most common.

Gold usually comes detachment veins hosted in metamorphic rocks such as quartz and slate which being eroded by floods igneous type (basalts, peridotites, andesites, granites, breccias and other large volume of coarse grains especially) that although gold is not specifically formed igneous bedrock drag him to these …

As an amateur, you can test a rock for gold in several ways.

1. Simple Field Tests. Many people confuse iron pyrite – fool’s gold – with real gold.
2. Placer Gold. Placer – also called nugget – gold is typically found by panning creeks, streams and rivers.
3. Crush the Rock.
4. Acid Test.
5. Hire an Assayer.

Natural gold, looks like gold, it looks like jewelry, it’s a buttery yellow color, and it’s “soft looking”. If you look closely you will also notice that the large rock that the gold ring, gold nugget and gold rock are sitting on has very sharp, fractured and angular shape. The gold however is smoother and rounded off.

Pyrite contains sulfur and iron. During World War II it was mined to produce sulfuric acid, an industrial chemical. Today, it is used in car batteries, appliances, jewelry, and machinery.

“Fool’s gold” is a common nickname for pyrite. Pyrite received that nickname because it is worth virtually nothing, but has an appearance that “fools” people into believing that it is gold. The value of this specimen to collectors of crystalline gold would be many times the value of its contained gold.

By starting your search for these rocks and minerals, you are essentially looking for a broader footprint of where the gold might be. However, Fool’s Gold is often found near actual gold deposits and serves as a sign that real gold is close at hand. You can often find this pyrite in creek beds while panning for gold.

Fool’s gold is made up of crystals and has sharp edges, while real gold is a metal with a smoother texture and rounder edges. If you look closely at the piece and see that its structure consists of what looks like small and sharp cubes, then it is fool’s gold.

Pyrite. Pyrite, which is a sulphide mineral composed of iron and sulphur, is a major contaminator of ground water and streams due to acid mine drainage from sulphide mine tailings. Oxidation of pyrite releases toxic metals and metalloids such as Arsenic (As), which is poisonous for humans.

“Fool’s Gold” is technically known as pyrite or iron sulfide (FeS2) and is one of the most common sulfide minerals. Sulfide minerals are a group of inorganic compounds containing sulfur and one or more elements.
