矿床为高中温热液型锡石硫化物矿床,通过研究知道随成矿温度由高到低,成矿阶段由锡石—石英经锡右硫化物到锡石—方解石,锡石晶胞的轴长,特别是c轴长和晶胞体积都有增大趋势。锡石中含有Fe等杂质元素,它们可以类质同像代替Sn,由于这些元素离子半径小,类质同像代替结果导致晶胞变小。而在高温条件下,元素类质同像代替较易进行,这就造成了高温阶段形成的锡石晶胞小,低温阶段形成的锡石晶胞大。
The orebodies are high-temperature hydrothermal cassiterite deposits. It is known from the study that as the metallogenic temperature changes from cassiterite-quartz to tin-cassiterite-calcite and the axis of the crystalline cell of cassiterite Long, especially the c-axis length and unit cell volume have an increasing trend. Cassiterite contains Fe and other impurity elements, they can be the same type of image instead of Sn, due to the small ionic radius of these elements, the same type of image instead of the results resulting in unit cell smaller. At high temperature, the elemental isomorphism is easier to replace, which results in the formation of small units of cassiterite at high temperature and the formation of large units of cassiterite at low temperature.
