How is turquoise formed?
For centuries, many scientists have painstakingly studied the natural processes and conditions of minerals such as gemstones formed in the earth, and this research has made breakthrough progress until the 20th century. Some scientists have found that the main factors that form a gemstone are the available chemical elements, temperature, pressure time and space. The formation of turquoise occurs in the pressure near the surface under normal temperature. The important medium of its formation process is rainwater. When the rain falls and infiltrates into the ground, some of the chemicals that are carried become weakly alkaline. After enough time, they are bred. Water dissolves rocks, and the dissolved rocks must be copper-bearing rocks, and they must first flow through some rocks containing soluble rare elements. When special aqueous solutions containing copper, aluminum, and phosphorus reach saturation, these chemical elements are deposited in the cracks and cavities of the rock with the appearance of new minerals. The turquoise deposits are formed in this way, which is called exogenous in geology. Forest filtration causes. Rocks meeting these conditions may be acidic volcanic eruptions and granites with secondary mineral apatite, or phosphorus-bearing sedimentary rocks and sedimentary rocks. Hubei turquoise is mostly produced from phosphorus-bearing sedimentary rocks and sedimentary metamorphic rocks. In the terrain, areas that meet these conditions and can be called turquoise deposits are rare. Interestingly, copper-bearing and gold-bearing metal deposits can be found under some turquoise deposits. Geologists classify turquoise deposits into two categories based on whether they have polymetallic deposits: One is a turbid rich belt with only dispersed metal mineralization, and the other is a secondary sulfide-rich zone with strong metal mineralization developed in its upper part. In fact, the formation of the turquoise is restricted by many factors. The turquoise is generally distributed in areas containing copper-sulfur compounds, phosphorus-containing layers or apatite-containing minerals and high aluminum content in surrounding rocks. It is mainly formed in the oxidation zone of the near surface and through the filtration of weathered forests. The turquoise of Hubei and other places is the mineral structure of the turquoise formed in this way, which is mostly tuberculous and shell-like. It is evidence that it is formed by the filtration of weathered forest under low temperature and low pressure. The nature is very complicated, the formation environment of the turquoise is not the same, and the conditions for the formation are different. The genesis of the pines may vary from place to place. For example, the formation of white pine is a mystery. In terms of geological factors, turquoise minerals are called fine veins and are formed along the weathered siliceous slate. When the pores of these rocks accumulate rainwater, it is convenient to form a turquoise deposit in the depth of the surface; how large the rock gap is, how much it may be; what shape of the void is, what shape the turquoise may grow into . In terms of chemical factors, since most of the turquoise minerals are symbiotic with minerals such as mineral kaolinite and limonite, obvious white traces are usually formed on the rock surface, and it is possible to dig along these traces. Dig into the turquoise. From this perspective, turquoise mines are relatively easy to find and are relatively easy to extract, and this is very important for the ancients who are extremely productive, which is why they have long been able to recognize and use turquoise.
