山东三山岛金矿床地质特征及找矿预测

Abstract

Abstract:

Sanshandao gold deposit,which is produced in Sanshandao-Cangshang fault belt,belongs to large-typical Jiaojia-Linglong type gold mine.Because of the reduction of resource,it is necessary to analyze mineralization and prospecting forecast,which can be used to direct the exploration in the deepness or surrounding of Sanshandao gold deposit.Based on the comprehensive analysis of spatial distribution of Ⅰorebody,and the trends of ore grade and thickness,combined with regional metallogenic characteristics,we think that the depth extend of Ⅰorebody is more than 2 000 m,the main minable-ore distribution in the plan or profile is in pod typology,the direct correlation was significant between magnetization intensity and alteration zone,as well as the quartz vein type orebody can be found in subsidiary fracture.Meanwhile,we also show that much more bucked ore is remain in the middle position between 28th line to 40th line,the deepness of Ⅰ orebody north position between 40th to 48th line,and the surrounding of Ⅰ orebody north position.We conclude that much more resources may be found in deepness or surrounding of Sanshandao gold deposit,and much exploration work should be done.
