http://geology.com绿松石是一种不透明的矿物,常呈现出蓝色,蓝绿色或黄绿色等美丽的色彩。千百年来,人们一直将绿松石视为一种珍贵的宝石。现代矿物学研究表明,绿松石实际上是一种含水铜铝磷酸盐,归类于磷酸盐矿物,分子式为(CuA l6(PO4)4(OH)8·5H2O)。一般认为,富含成矿元素的流体长期的沉淀作用,是绿松石形成的最主要的原因。绿松石在形成的过程中,其硬度因成矿过
http://geology.com Turquoise is an opaque mineral, often showing beautiful colors such as blue, turquoise or yellow-green. For thousands of years, turquoise has been regarded as a precious gem. Modern mineralogical studies have shown that turquoise is actually a water-containing copper-aluminum-phosphate, classified as a phosphate mineral with the formula (CuAl6 (PO4) 4 (OH) 8 5H2O). It is generally believed that the long-term sedimentation of fluids rich in ore-forming elements is the most important cause of turquoise formation. Turquoise in the formation process, its hardness due to mineralization
