| 摘 要： | 芙蓉矿田锡矿床按成因可分为构造蚀变带-矽卡岩复合型、构造蚀变带型、蚀变岩体型、矽卡岩型、脉状云英岩型等五种类型。各类型矿体中锡主要以锡石锡的形式出现,其分布率由92.17~97.77%,硫化锡、胶态锡、硅酸锡的分布率<8%。锡元素在钠长石化成矿作用阶段,很可能是以氧的络阴离子SnO33-、氢氧络阴离子〔Sn(OH)6〕2-的形式迁移;在云英岩化成矿作用阶段,主要以氟的络合物,如Na2SnF6,Na2〔Sn(OH、F)6,〕SnF4,K2SnF6等形式搬运;到了绿泥石化锡石硫化物阶段,锡又以硫化锡酸盐、硫化物(Na2SnS3,SnS2,SnS)和氯的络合物(Na2SnC l6)、氟的络合物等形式进行迁移和搬运。

| Abstract: | Tin mineral deposit of the Furong ore field can be divided into five types such as the structural alteration-skarn compound type,structural alteration zone type,alteration type of rock body,skarn rock type and vein greisen type,according to the genetic type of ore deposits.In various types ore body,tin is mainly form of the tin by the cassiterite appearance.Its distributing rate is by 92.17-97.77%,tin sulfide,colloidal tin,distribution rate of the tin silicic acid <8%.During the albitization ore-forming stage,tin is probably removal by comple negative ion SnO33-of oxygen and hydrogen-oxygen comple negative ion(Sn(OH) 6) 2-form;During the greisen mineralization stage,it is mainly with the complex of Fluorine such as Na2SnF6,Na2(Sn(OH,F) 6),SnF4,K2SnF6,etc.;The chloritization cassiterite sulphide stage,tin move and carry by sulfide tin sour,sulphide(Na2SnS3,SnS2,SnS),complex(Na2 SnCl6),complex of Fluorine of chlorine etc. |
