The gold-bearing quartz seams may follow joints formed in certain directions of shear within the large masses of rock; or in the case of limestone, the quartz may fill areas eaten away by the mineralizing solutions replacing the rock as a whole.
2020-12-30 · hi there, just started prospecting I have a mountain of this quartz on my property, with a gpx 5000 on factory setting, I receive a low-med single ,but with a high mineral setting ,no signal! looks like rust spots and I think pyrite. I crushed a piece and paned,lots of fine gold looking spots u...
1) Not all white quartz will contain gold lines. 2) Gold is also found in non-rusty quartz. 3) Some thicker (cruder) gold lines will be iron pyrite. The reason we do the scratch test is to determine if we have located gold of golden colored pyrite. Gold will dent and is soft. Anything else that is not a
Pyrite often replaces plant debris and shells to create pyrite fossils or flattened discs called pyrite dollars. In calcite and quartz veins, pyrite oxidizes to iron oxides or hydroxides such as limonite, an indicator that there is pyrite in the underlying rock. Such oxidized zones are

Take a rock that contains gold in it this process works best on quartz rocks and set it inside a glass jar. Add white cooking vinegar to the jar, covering the entire rock and then some with the vinegar. The acid-based vinegar slowly dissolves the quartz crystals surrounding the gold, leaving only bits of quartz attached to the gold.
2020-8-15 · Non-Destructive Tests. A) Tarnish: Most specimens of pyrite, found in nature, will have at least some tarnish on their surface. Nuggets or small flakes of gold are usually bright and untarnished. B) Color: Pyrite has a brassy color. Gold has a golden to yellow color. Most native gold is alloyed with silver, and if the silver content is high enough, the specimen will have a whitish yellow color.
2011-7-1 · Gold deposits related to magmatic fluids at 150–250 °C are generally accompanied by wall-rock alteration, with a mineral assemblage of quartz + K-feldspar + pyrite ± illite ± anhydrite ± calcite, as is the case for Ladolam.
