Where is beryllium found in Utah?
Spor Mountain
Beryllium deposits containing bertrandite (2Be2 Si04·H? 0) occur in tuffs on the fiats surrounding Spor Mountain in the western part of the Thomas Range in western Juab County, 46 miles northwest of Delta, Utah. The first beryl- lium deposit was found in December 1959, and others were found in 1960 and 1961.
Is gold found in hydrothermal deposits?
Gold is primarily hosted in chalcopyrite, arsenopyrite, pyrrhotite and pyrite in most hydrothermal gold deposits, and its concentration in sulfide varies to a great extent (Morey et al., 2008, Large et al., 2009).
What rock is found with gold?
quartz
In auriferous quartz lodes the minerals most commonly associated with gold are iron and copper pyrites, zinc blende, galena, and tetradymite. Tellurides of gold are very widely distributed. Other minerals occurring with gold are tourmaline, calcite, uranium ochre, roscoelite, vanadinite, crocoite, wollastonite, gypsum.

What is the difference between placer gold and lode gold?
Gold is found in two basic forms in the US, placer gold and lode gold. Lode gold is embedded in hard rock ore and must be mined with shovels, pick axes, jackhammers, and the like from open pit mines or mine shafts. Placer gold is residual gold flakes or nuggets that can be collected by panning or dredging.
How do you know if soil is gold?
Iron staining is another excellent indicator that gold may be present. The iron stains are in yellow or reddish soil. Soil which contains iron may also be black, provided it has not oxidized. Where iron or other heavy metals are located, gold may also be found.

How can you tell a rock is gold?
You’re looking for a scratch on the glass. If the glass gets scratched from the ‘gold’, it’s not actually gold. Since glass has a hardness of around 5.5 it will only be scratched by harder minerals like pyrite and quartz. If the glass doesn’t scratch then that’s a great sign – you likely have gold in your rock!
What type of rock is gold found in?
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.
How do you tell if a rock has gold in it?
One of the easiest and most telling tests for gold that you can perform on your rock is for hardness. This test is an application of Mohs hardness scale, which compares the hardness of different minerals by scratching them against one another.
