锡矿山锑矿床各类方解石中，含矿脉状方解石含锑最高。从早期到晚期方解石，锑等元素含量逐渐降低。方解石的稳定同位素、流体包裹体及稀土元素地球化学研究表明，成矿溶液具低盐度和中—低温的特点。它是由通过前泥盆系的深循环天水形成。下渗雨水与热液混合是导致热液沉淀成矿的原因之一 In the various types of calcite in the antimony deposit, the vein-bearing calcite contains the highest amount of antimony. From early to late calcite, antimony and other elements gradually reduced. Stable isotopes of calcite, fluid inclusions and REE geochemical studies show that the ore-forming solution has low salinity and medium-low temperature characteristics. It is formed by the deep circulation of Tianshui through the former Devonian. Infiltration of rainwater and hydrothermal mixing is one of the reasons leading to hydrothermal sedimentation
