| 摘 要： | 狼洞沟金银矿床是浑江古生界凹陷中发现的第二个小型矿床,通过对矿床的矿体形态﹑矿石组成﹑结构构造﹑围岩蚀变﹑硫同位素测定及矿石爆裂温度测定分析,成矿物质来源于含矿岩体和地层,在成岩成矿作用中,岩浆同熔和交代作用较强烈,其成矿期可分二期,成矿温度可划分三阶段.认为狼洞沟金银矿床是与中温浅成岩浆热液有关的裂隙充填脉状金银矿床.

| Abstract: | Langdonggou Au-Ag deposit is the second small ore deposit in Paleozoic depression.Through the analysis of the ore body shape,ore composition,structure,wall rock alteration,S isotopic determination and ore decrepitating method,it is considered that metallogenitic material derived from the ore-bearing rock body and the stratum;in lithogenesis and mineralization,magmatic syntexis and metasomatism are relative intense,The metallogenenic epochs can be divided into two one,and the metallogenic temperature can be divided into three stages.The study shows that Langdonggou Au-Ag deposit related to mesothermal shallow-seated magmatic hydrothermalism,which belongs to fissure filling vein Au-Ag deposit. |
