| 摘 要： | 西秦岭西段同德-河南县一带汞锑矿分布广泛,矿化明显受地层和构造控制.矿体主要分布于三叠系中,赋矿岩石为长石石英粉砂岩、泥板岩、硅质岩和角砾碎屑灰岩.对成矿物质来源研究后,认为汞主要来源于深部.由于辰砂等成矿物质熔点低,易于气化.在地壳深部呈气态形式存在,易于被有机质吸附并储存起来,因汞气的不稳定,它会不断进入水介质形成含矿热液,并通过运移在适当的地质条件下形成矿床.

| Abstract: | Mercury antimony ore is widely distributed over the zone of western area of west Qinling Mt.,Tongde and Henan County,the mineralizing was obviously controlled by texture and stratum.The ore body is mainly deposited in Triassic system and contains within feldspar quartzite,siltstone,pellite,silicolite and anguclast limestone.As the study for the resource of minerogenetic material,we found the mercury is mainly from the deeper,because it is easy to be gasification due to the lower fusion of the minerogenetic material as mercuric blende and also was adsorbed by organicity,meanwhile as the unstability of mercury gas,it went to the medium of water and exist by gaseity under the deeper of the Shell and then formed ore bed on the proper condition. |
