why Granite is composed of quartz, potassium feldspar, and plagioclase feldspar?
Gold that is found in quartz is normally transferred there as a dissolved ion in migrating hot water. Chemical changes occur as the water migrates around in the crust, leading to the deposition of gold, metal sulfides, carbonate minerals, and quartz (all of the constituents of these minerals are easily dissolved in very hot salty water). You will note that the quartz that contains gold is usually found in a vein, which is simply the old fracture that the water migrated through at some point in the past, but eventually the fracture filled up with quartz. Quartz (and quartz-carbonate-sulfide) veins are very common in areas where there are deposits of gold.
people are making the crop circles no longer extraterrestrial beings from outer area. I observed a documentary on television of a collection of people responsible for many remarkable complicated crop circles they confirmed the way it grow to be completed. it is not that complicated besides the undeniable fact that it somewhat is an outstanding style of artwork.
Actually, gold can be made. It has to do with its atomic arrangement that makes it gold. (Gold is an element). Any element that is heavier than gold can be divided to have gold as a bi-product and any elements that are lighter than gold can be combined to produce gold (provided you arrive at the correct atomic arrangement...sounds simple when you say it). The problem is, with current technology, it costs more to produce the gold than it is actually worth, so you end up with a negative return. Quartz is formed under intense heat and pressure, which can provide enough free enegy for other reactions to happen, allowing things to form. Gold could be one of them.
