Lode and Placer Gold

It is possible to come across a gold strike in a hunting, camping or fishing trip. However, for those specifically looking for gold, one of the most important aspects to learn is the how to’s on the types of placers that exist, which are lode and placer. So how can person differentiate the type of placer he or she has come across? And how did they come about? In this process the gold of main deposits is carried along with other metals into the main and highest part of the crust of the earth with the help of water that has risen or hot water that have been under pressure and have followed cracks of fractures that have been formed by the movements of the earth. These cracks are like that of a plumbing system and in which the solutions from deeper depths can move upwards until they meet with rocks that are cooler. In most cases, these previous areas are in the distance of a few thousand feet from the surface. In areas where the temperatures and pressure is lower, minerals begin to crystallize from the solutions. The crystalline materials, as well as gold if there is any in them, gather along fracture surfaces and little by little fill up the holes along cracks and form what is known as veins. The solutions might keep going upwards, then mix in with water in the ground, and come out to the surface as hot springs. There are a number of speculations that geologists have come up with to explain the source of the mineralizing solutions. There is one hypothesis that says that the solutions that are left or expelled from the molten rock when it becomes cooled, starts to crystallize at a distance of many thousands of feet under the surface of the earth and that these are formed into mineral deposits. The more volatile parts of the molten rock have the heavy and precious metal inside, like gold for instance, and these are the ones that crystallize last. In areas where the cracks are formed by the movements of the earth that can be found in and on top of molten rock, the more volatile minerals have left to the top levels of the earth’s crust. When the solution is expelled, from the crystallizing liquid rock is mainly water but takes along with it silica as well as other metallic substances like that of gold.
