  • In What Rock Formations Can Gold Be Found? Sciencing

    Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

  • How to Identify a Gold Bearing Area Sciencing

    (See Reference 1.) Various hypotheses exist on how gold is formed as it surfaces in numerous types of volcanic and sedimentary rocks. Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds.

    The gold is found not only in the bedrock, but in gravels as much as two feet above the bedrock. In the original pay-streak on Wade Creek, gold is found as deep as 1 1/2 feet into the bedrock. The origin of the gold is supposed to have been from the quartz stringers in the schists. The gold becomes black toward the head of Wade Creek.

The occurrence of gold mainly depends on temperature, pressure, pH values, Cl − concentration, and fugacity of H 2 S in a hydrothermal system. Gold mostly occurs as AuCl − 2 in a system with temperature higher than 400 °C (Gammons and Williams-Jones, 1997), and with decreasing temperature being the primary mechanism causing gold

  • Rock Layers: Timeline of Life on Earth Prehistoric Planet

    Rock layers are usually ordered with the oldest layers on the bottom, and the most recent layers on top. The Law of Faunal Succession explains that fossils found in rock layers are also ordered in this way. The Three Layer Cake There are thousands upon thousands of layers in the earth's crust. However, scientists have grouped the layers into
