geology lessons on how to find gold with rock and gold 101. we teach you what rock and minerals to look for when prospecting for gold. if you know what to look for then it makes finding gold easy.
orphaned mineral mines in virginia gold in virginia fact sheet. gold was mined extensively in virginia from the early 1800s until the peak of gold production in 1849. in that year, major gold discoveries in california had a negative impact on virginias gold mining industry, and production declined rapidly.
of all the minerals mined from the earth, none is more useful than gold. its usefulness is derived from a diversity of special properties. gold conducts electricity, does not tarnish, is very easy to work, can be dn into wire, can be hammered into thin sheets, alloys with many other metals, can
in gold-bearing country, prospectors look for gold where coarse sands and gravel have accumulated and where black sands have concentrated and settled with the gold. magnetite is the most common mineral in black sands, but other heavy minerals such as cassiterite, monazite, ilmenite, chromite, platinum-group metals, and some gem stones may
gold is resistant to weathering, but flakes and dust are easily transported via streams that surround gold-bearing geologic formations. placer deposits accumulate in stream beds and in sand and gravel, also known as 'black sands,' and are heavier than other types of minerals.
a video which includes several points on how to find gold and minerals, what to look for and the best locations were we find our deposits. also includes a few gold, silver and copper ore samples

geology and resources of gold in the united states introduction to geology and resources of gold, and geochemistry of gold the case for gold an introduction to geology and resources of gold in the united states by daniel r. shawe abstract gold has long been a store of wealth, whether held by governments or in private hoards.
the effort to understand the geology of gold was perhaps man's first serious effort at understanding the earth's rocks and minerals. gold is actually a relatively scarce element on the crust of the earth, but it occurs in trace quantities spread throughout many different kinds of rocks and in many different geological environments.
to know what type of rock is gold associated with you must see that the minerals most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes; wolfram, scheelite, brookite and diamonds are less common. diamonds are associated with gold in brazil, and also occasionally in the urals and in the united states.
gold geology and the natural indicators that can help you find gold. not all gold deposits out there have been found and mined. there are still places that contain gold that have never been worked, despite the fact that miners have been searching for gold for hundreds of years now.
worldwide, there are two types of gold deposits. in situ or lode deposits are disseminations of metallic gold in quartz veins, traces of gold contained in certain sulfide minerals, or extremely fine-grained particles dispersed in host rocks. placer deposits form from weathering and erosion of rocks containing gold.

in geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. the hydraulic flow involved is usually due to hydrothermal circulation.
native gold is an element and a mineral. it is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties - some of which are unique to gold. no other element has more uses than gold. all of these factors help support a price of gold that is higher than all but a few other metals.
