【摘要】 内蒙古自治区已发现的火山岩型铅锌矿(陆相)规模较大,集中分布于大兴安岭地区,与中晚侏罗世火山活动联系密切,已知矿床的深部及外围找矿潜力巨大。依据前人的地质、矿产、物探、化探等资料,采用"火山岩型"预测方法类型,分别以比利亚谷铅锌矿、甲乌拉铅锌矿和扎木钦铅锌矿作为典型矿床,在全区选取比利亚谷、甲乌拉和扎木钦3个预测工作区进行矿产预测。圈定铅锌矿最小预测区109个,其中A级最小预测区18个,B级最小预测区37个,C级最小预测区54个。预测334-1级别Pb+Zn总资源量1732548t,334-2级别Pb+Zn总资源量588930t,334-3级别Pb+Zn总资源量4608682t。可利用的Pb+Zn总资源量为3179267t。反映内蒙古大兴安岭地区中生代火山岩型铅锌矿(陆相)找矿潜力较大。更多还原

【Abstract】 Large-scale volcanic lead-zinc deposits have been discovered in Inner Mongolia.They are concentrated in the Greater Kh-ingan Range and closely related with the Middle-Late Jurassic volcanic activities,and have a great prospecting potential in the deep ar-ea of the deposits and their peripheral area.Combined with the previous geological mineral resource,geophysical and geochemical dataand taking the Biliyagu,Jiawula and Zhamuqin lead-zinc deposits as typical deposits,this work used the volcanic type prediction meth-ods to conduct metallogenic prediction for the Biliyagu,Jiawula and Zhamuqin prediction areas.We delineated 109 minimum predictionareas,including 18 A types,37 B types and 54 C types.In addition,the total amount of lead and zinc resources was determined,inclu-ding 1 732 548 t of 334-1 type resources,588 930 t of 334-2 type and 4 608 682 t of 334-3 type.The total amount of the available leadand zinc resources is 3 179 267 t.This suggests a great potential for prospecting Mesozoic continental volcanic lead-zinc deposits in theGreater Khingan Range of Inner Mongolia.更多还原
