Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.
文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件,进行Re-Os等时线年龄测定,得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma,其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma,成矿时代为中侏罗世,对应于燕山早期第二阶段;从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma,石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。

Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.
说明早期成矿流体为富含CO〓、H〓O等的碱性流体,其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源,带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化,带出的Na〓则在浅部形成钠长石脉。
