摘要
研究表明,大别山棋盘格子构造是控矿＂温床＂,为深部作用激发表壳构造的耦合成矿模式提出了。大别山地区钼多金属矿床大致可分两期,即在142~130Ma之间的第一期斑岩型钼（铜）成矿期和在128.7~113.1Ma之间的第二期斑岩型单钼成矿期;区内钼矿床主要产于燕山期中酸性斑岩体及其内外接触带,由于围岩性质的差异,而形成斑岩型、矽卡岩型、石英脉型和隐爆角砾岩型钼多金属矿床。
Checkerboard lattice structure in the Qinling-Dabie orogenic belt is ore-controlling ＂hotbed＂ which resulted in coupling ore formation of crustal structure aroused by deep processes. Molybdenum polymetallic ore-formation in the Qinling-Dabie orogenic belt may be divided into two phases such as porphyry type Mo-Cu ore-formation during 142-130 Ma and porphyry type Mo ore-formation during 128.7-113.1 Ma. The Mo deposits occur in Yanshanian intermediate-acid porphyry and endocontact and exocontact, forming porphyry type, skarn type, quartz vein type and cryptoexplosive breccia type Mo polymetallic deposits.
