含锡花岗岩外带的银铅多多谢矿床地质特征

滇东南与滇西矿带内，与隐伏或出露的含锡花岗岩有关的芦塘坝、龙树、白牛厂、坝脚及滇西大矿山、澜沧老厂等银铅多多谢矿床，在成矿特征、矿石矿物组合、伴生元素等有极大的相似性，称为含锡花岗岩外带型银铅多金属矿床是一种新的银矿类型。     

Formation of Strata—bound Ore Deposits in China：Studies on Fluid Inclusions

Fluid inclusion studies were made on the basis of the geological data on the strata-bound ore de-posits of China including those of Pb,Zn,Au,Ag,Sb,U,Hg,W,quartz-crystal and sparry-calcite.An attempt was made to approach the model of formation for each type of ore depos-its by considering the material sources,the migration of fluids and the conditions of mineralization.It is found that ore-forming fluids (especially H2O)originate as heated underground water reacts with the wallrocks and dissolves Na^ ,Ca^2 ,K^ ,Cl^ ,HCl^- and Mg^2 .The ore fluids are mainly of NaCl-Ca-HCO3-H2O system with salinities ranging from 4to 14wt.%.NaCl equivalent and densities ranging from 0.9 to 1.0g/cm^3.It may be concluded that the deposits were formed at temperatures ranging from 150 to 250℃ under pressures from 300 to 1000 bars.Ore deposition may have been controlled by temperature and pressure or by the mixing among different fluids.     

论煤中伴生元素的成因分布类型

通过对230余幅元素分布类型图的分析,将煤和岩石中的伴生元素划分为原生型(服从正态分布)、叠加型(服从对数正态分布)、流失型(服从负偏斜对数正态分布)、再生型(呈非正态分布)和复合型(呈混合态分布)等五种成因类型。     

绍兴—龙泉不同成因类型金(银)矿床的成矿特征及分布规律
