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

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.
