Rockhounding and Mineral Collecting

It has no official rock, stone, gem or mineral.

The red color is caused mainly by the presence of the element Chromium.

The vacuole in plant cells contains water and dissolved minerals. It helps regulate water content and maintain turgor pressure within the cell.

A hollow diamond drill bit, with lots of water, cutting slowly, will do the job. Ideally in a drill press of some kind instead of freehand. Diamond bits in rotary tools like Foredom or Dremel may do it, if it's suitable to use them with lots of water.

A mineral that breaks into jagged pieces exhibits fracture.

A jade stone massage is when jade stones are warmed and placed in different places on your body. It is thought that this helps direct energy and healing where you need it most.

Platinum, like gold, can be alluvially transported from a lode and found in ore-grade sand deposits, so yes, conceivable, platinum ores can be found on the beach. Platinum nuggets from placer deposits are far rarer than gold nuggets and are highly valued by collectors.

yes, I use the site all the time.

It's really safe and you don't have to give out any personal information! :)

Gold is a naturally occurring element (element symbol Au, atomic number 79), that is created in nature e.g. during supernovae explosions of type II (see link "supernovae nucleosynthesis").

It also has been created in amounts of a several atoms by nuclear transmutation (see respective link), but it cannot be "created" or "destroyed" in the classical sense of chemistry.

On earth, gold is found mostly in solid form in veins in siliceous rocks. By alteration, it can be eroded and placed in form of powder, granules or nuggets in the riverbeds. Low concentrations of dissolved gold can also be found in the sea.Occurrence in nature

Gold occurs in nature in both its native state and in compounds. The native state of an element is its free state. It is not combined with any other element. The most common compounds of gold are the tellurides. A telluride is a compound of the element tellurium and one or more other elements.

At one time, gold was found in chunks or nuggets large enough to see. People mined gold by picking it out of streams and rivers. In fact, gold was once very common in some parts of the world. People valued it not because it was rare, but because it was so beautiful.

The abundance of gold in the Earth's crust is estimated to be about 0.005 parts per million. That makes it one of the ten rarest elements in the Earth's crust. Gold is thought to be much more common in the oceans. Some people believe as much as 70 million tons of gold are dissolved in seawater. They also think there may be another 10 billion tons on the bottom of the oceans. So far, however, no one has found a way to mine this gold.

About a quarter of the world's gold comes from South Africa. Other leading producers of the metal are the United States, Australia, Canada, China, and Russia. In the United States, about two-thirds of its gold is mined in Nevada. California, Montana, Alaska, and South Dakota also produce gold.

Calicite is mined in same way that limestone is mined which entails just collecting the deposits. However, the production s quite an involving process which starts with the separation of different grades and removal of unwanted impurities. It is then crushed and subjected to froth flotation.

Three metals that are mined in Argentina are gold, silver, and copper.
