新疆和田玉是由于昆仑山-阿尔金山脉在远古时期地壳隆起的剧烈运动时,板块活动带中有强烈的断裂活动和岩浆活动。由透闪石、橄榄石和透辉石等矿物质在热液交代时,在合适的压力、温度条件下形成的。任何矿物的形成,都离不开温度和压力。尤其是矿物晶体的形成,必然是由液态转变成固态,也就是由高温转变至低温。因此,宝玉石品质的好坏,主要决定因素在于初始成矿时的温度条件,即高温条件和低温条件。一、高温结晶在高温条件下形成的宝玉石,由于岩浆在高温条件下凝固的,多种矿物质来不及分离,杂质也来不及析出。多种物质混在一
Hetian jade in Xinjiang is due to the intense tectonic activity and magmatic activity in the tectonic belt of the Kunlun Mountains-Altun Mountains during the vigorous uplift of the ancient crust. By the tremolite, olivine and diopside and other minerals in the hydrothermal replacement, formed under the conditions of the appropriate pressure and temperature. The formation of any mineral, are inseparable from the temperature and pressure. In particular, the formation of mineral crystals is bound to be transformed from liquid to solid, that is, from high temperature to low temperature. Therefore, gem quality is good or bad, the main determining factor is the initial temperature of metallogenic conditions, that is, high temperature and low temperature conditions. First, the high temperature crystallization Gem in the formation of high temperature gem, due to the high temperature in the magma under the solidification of a variety of minerals too late separation, impurities too late precipitation. A variety of materials mixed in one
