我国石材资源丰富,品种繁多,但主要是花岗石、大理石和板石三种。前不久在新疆的萨孜勒克变质岩系中,又发现了有5种颜色的石英岩,主要矿物成分为石英(含SiO_2>95％),结构致密,质地细腻油润,微透明至半透明,色彩鲜艳、纯正,有的还在基色中有天然图案、纹理,硬度高,强度 China’s stone resources are rich and varied, but they are mainly granite, marble and slabstone. Not long ago, in the Salimuk metamorphic rock series in Xinjiang, quartzite with five different colors was also found. The main mineral composition is quartz (containing SiO2>95%). The structure is dense, the texture is delicate and oily, slightly transparent to half Transparent, colorful, pure, some still have natural patterns, textures, high hardness, strength
