河北承德地区钼矿成矿地质特征及成矿预测

承德地区位于华北地台北缘中段受EW、NE和NNE向断裂联合控制的钼（铜）多金属成矿带上。20世纪，在该区先后发现了斑岩型撒岱沟门钼矿床、矽卡岩型寿王坟钼多金属矿床和脉型大草坪钼矿，显示出该区具有良好的成矿背景和找矿前景。该区钼矿床的形成与燕山期中—酸性小侵入体关系密切，矿床多产于花岗斑岩体之中或其内外接触带中。在充分收集承德地区典型钼（铜）矿床地质资料的基础上，结合前人的研究成果，系统总结了承德地区钼矿床的地质特征、矿床类型及时空分布规律，预测了该区钼矿找矿方向和靶区，为加强区内钼矿资源勘查、实现该区钼矿找矿突破提供参考。

Metallogenic Geological Characteristics and Prognosis of Molybdenum Deposit in Chengde, Hebei Province

Chengde area is located in molybdenum （copper） polymetallic metallogenic belt controlled by EW,NE and NNE trending fault in middle north margin of North China platform.Several deposits have been successively found in this area, such as Sadaigoumen porphyry molybdenum deposit, Shouwangfen skarn Mo-polymetallic de- posit and Dacaoping vein type molybdenum deposit,which shows that this area has a good ore-forming background and prospecting potential.These molybdenum deposits are associated with Yanshanian intermediate-acid granites in time and space.The deposits are usually distributed along the internal or external contact zone of the granite por- phyry or in rock bodies.Based on sufficiently collecting and studying the existing data of the typical molybdenum （copper） deposits in Chengde area,combined with the former research results,this article systematically summarizes geological characteristics, deposit types and spatial and temporal distribution of molybdenum deposits in this area, prospecting direction and target in the future is also proposed.It has important significance for strengthening re- sources exploration and prospecting breakthrough of molybdenum deposits in this area.
