中文摘要:[摘要]近年来,内蒙古钼矿勘查取得了一系列新进展,相继发现和探明了大苏计、乌兰得勒、小狐 狸山等大中型钼矿,正在勘查的查干花、激流河和迪彦钦阿木钼矿具有特大型远景规模。本文在对近几 年新发现典型钼矿床研究的基础上,运用区域成矿学理论,初步总结了内蒙古钼矿区域成矿规律。认为 内蒙古钼矿床成矿均与岩浆活动有关,主要成矿类型为斑岩型和火山-次火山岩型。成矿时代则主要为 加里东中晚期、华力西晚期、印支期和燕山晚期4 个时期。初步提出6 个钼矿成矿系统,划分出9 个钼 矿成矿远景区。研究分析认为内蒙古钼矿成矿条件优越,斑岩型及火山-次火岩型( 铜) 钼矿床的找矿 潜力仍然非常巨大。

New Progresses in Exploration of Molybdenum Depositsand Analysis of Mineralization Prospect in Inner Mongolia
Abstract:Abstract:A series of new progresses have been made in molybdenum deposit exploration in Inner Mongolia in recently years,such as the Dasuji mo鄄 lybdenum deposit,Wulandele molybdenum deposit,and Xiaohulishan molybdenum deposit that have been discovered and exploited successively. And the Chaiganhua molybdenum deposit,Jiliuhe molybdenum deposit,and Diyanqinamu molybdenum deposit are under exploring. These deposits have probably a good prospect of extremely large scales. This paper studies these new discovered deposits. Using regional metallogenic theory,we summarize molybdenum deposit formation rules in Inner Mongolia. We think that the source of all molybdenum deposits is related with magmatism in this region. The major deposit types include porphyry molybdenum deposits and volcanic-subvolcanic molybdenum deposits. The metallogenic periods of ore formation are the middlelate Caledonian,late Variscan,Indo-China and late Yanshan. Periods. Six molybdenum metallogenic systems are suggested,from which nine prospective molybdenum deposits are speculated. We think the molybdenum metallogenic conditions are excellent,and there is a bright exploration prospect of porphyry (copper) molybdenum deposits and volcanic-subvolcanic (copper) molybdenum deposits in Inner Mongolia.
