How tin prospecting, you know? Qingzhou Guancheng company told you
1、花岗岩区或隐伏花岗岩区；
1, the granite zone or concealed granite area;
2、大理岩、角岩、矽卡岩、云英岩、电英岩区；
2, marble, hornfels, skarn, greisen, tourmalite district;
3、流纹岩、花岗岩、花岗质斑岩内及其接触带附近，个别富锡地区的超基性岩、辉长岩；
3, rhyolite, granite, granitic porphyry and near the contact zone, ultramafic rocks, gabbros individual tin rich region;
4、重砂测量。因锡石硬度大，不溶于一般的酸碱，在自然风化状态下相当稳定，因此常以重矿物产于水系沉积物的底部。从风化土层和水沟沉积物中取样，淘洗，看有否锡石或木锡存在。木锡是Sn4+的盐类水解，分凝出Sn(OH)4的溶胶和凝胶，脱水后而形成的，形似木头状物质；
4, heavy mineral measuring. Because of cassiterite hardness large, insoluble in general acid-base, under natural weathering conditions are quite stable, so often in the heavy minerals in sediments at the bottom. From the weathered soil and water sediment sampling, washing, see there is no tin or tin wood. Wood tin salts hydrolysis of Sn4+, segregation of Sn (OH) 4 sol and gel, formed after dehydration, the shape of the wood like material;
5、硅化带、石英脉、硫化物石英脉；
5, silicified zone, Shi Yingmai, sulfide quartz vein;
6、断裂破碎带、铁帽、巧克力土（含锡矽卡岩、大理岩风化而成的土壤）；
6, fracture zone, gossan, chocolate soil (tin bearing skarn, marble weathering soil);
7、富氟岩石及蚀变岩。锡易与氟形成络合物迁移，当锡沉淀后，氟就滞留在附近的岩石内。因此，氟、硼、锡、砷、锑、铜等异常可指示锡的成矿远景区，且可预测锡的储量的大小。
7, fluorine rich rocks and altered rocks. Tin and fluoride complexes of migration, when the tin deposition, fluorine retention in the vicinity of the rock. Therefore, metallogenic fluorine, boron, tin, arsenic, antimony, copper and other abnormal indication of tin, tin reserves and can predict the size of the.
