山东玲珑金矿石英成因矿物学研究及其找矿远景的确定

GENETIC MINERALOGY OF QUARTZ AND ORE PROSPECT OF THE LINGLONG GOLD MINE,SHANDONG

玲珑金矿是我国目前最大、开采历史最久的含金石英脉型金矿之一。已有许多地质学者对其多方面进行了大量研究,但对最重要的脉石矿物—石英,仍有必要系统研究,为这个老矿山的远景找矿和那些尚未勘探的石英脉的含矿性评价提供有用信息。

The Linglong gold mine is one of the oldest gold mines in China. Now it facesa crisis of reserves and is in urgent need of an evaluation of the prospect of itstwo ore districts and the ore potentiality of quartz veins that have not been pro-spected. Based on a study of the occurrence, physical properties, crystal habits,micromorphology, chemical composition, inclusions, thermoluminscence and infrared spectrum of vein quartz, the typomorphic characters for evaluating the ore poten-tiality of quartz veins have be summarized. By comparison of the physicochem-ical conditions of vein quartz in the two districts during its formation, it hasbeen found that ores of the Eastern Hill ore district show the features of theorebodies of its upper part while ores of the Western Hill ore district show thefeatures of the orebodies of its lower part. The Linglong fault elevated the lowerorebodies of the Western Hill ore district to the level of the upper orebodies ofthe Eastern Hill ore district after mineralization. It is concluded that the ore pro-spect at the deep levels of the Eastern Hill ore district is far more promisingthan that of the Western Hill ore district. This conclusion has been continuallyproved by explorational operation.
