    PRIMARY STUDY ON PETROCHEMICAL CHARACTER OF THE GOLD BEARING GRANITES OF PHANEROZOIC EON,CHINA

    • 摘要: 赋存于花岗岩中的金矿床在我国金矿资源中的地位极其重要,并形成我国独具特色的金矿类型。我国含金花岗岩的时代,绝大多数为燕山期,其次是华力西-印支期及加里东期;含金花岗岩体分布广泛,特别集中出露在中朝板块东缘的胶东地体内和北缘广大地区,在北方陆壳增生区及华南扬子板块内亦有分布;研究表明,含金花岗岩类以Ⅰ型花岗岩为主,其次是A型和S型;在同一地区含金花岗岩的金丰度明显高于不含金花岗岩。

       

      Abstract: The gold deposits occurred in granites play a important part in the construction of goldresotirces in china,and is a special type of the gold deposits.The gold-bearing granites weremostly formed in Yanshan period,secondly in Variscan-Indosinian and Caledonian peri-ods.The gold-bearing granites widespreadlly distributed in the Shandong terrain of the eastmargin of Sino-korea plate.North margin of Sino-Korea plate,the continental crust-ac-cretion areas of north China and Yanzhi plate of south China.Study shows,the gold-bearinggranites can be dividec Ⅰ-type,A-type and S-type,mostly is Ⅰ-type.The gold-abun-dance of the gold-bearing granites are higher than graniteswhich don' tbear gold in thesame place.
