| 中文摘要: |
| 黑龙江省东安-汤旺河地区，东安式、团结沟式浅成低温热液型金成矿作用与早白垩世次流纹岩（隐爆角砾岩）-花岗斑岩（碱长花岗岩）构成的火山-侵入杂岩体密切相关。翠宏山矽卡岩-热液充填型铁铅锌多金属矿和霍吉河斑岩型钼矿床的成矿二长花岗（斑）岩体的精准年龄（186~199Ma），与小兴安岭东南鹿鸣斑岩型钼矿、小西林矽卡岩-热液充填型铅锌矿的成矿二长花岗（斑）岩体年龄（180~207Ma）之间具很好的耦合性，成矿时代为燕山早期-印支晚期。结合近期逊克翠中铁矿、高松山金矿和高岗山钼矿等的勘查进展，初步梳理了区域中生代岩浆作用与金钼铁等多金属矿成矿作用，以及制约找矿突破的一些地质问题，提出了钼铁铅锌矿勘查以印支晚期-燕山期二长花岗岩岩基体成矿，金矿勘查以燕山晚期火山-侵入杂岩体及火山机构成矿的找矿思路和今后的找矿方向建议。 |
| 英文摘要: |
| Gold deposits in the Dongan-Tangwanghe area of Heilongjiang Province are characterized by the epithermal mineralization of Dongan and Tuanjiegou style in the Yanshanian epoch, which are closely related to the rhyolite (cryptoexplosive breccia) - granite porphyry in the early Cretaceous epoch. The precise ages (186~199 Ma) of the metallogenic monzonite granite-porphyry from the Cuihongshan skarn-hydrothermal filling type lead zinc polymetallic deposits and Huojihe porphyry molybdenum deposits correspond well with the monzonite granite-porphyry of Luming porphyry molybdenum (gold) deposits and Xiaoxilin skarn-hydrothermal filling type lead-zinc deposits in the southeast of Xiaoxing’anling, of an early Yanshanian period (late Indosinian). Based on the recent major exploration results, this paper summarized the regional metallogenic regularity, and the key geological problems which have limited the prospecting breakthrough of Au-Mo-Fe deposits, and put forward the prospecting strategy and exploration deployment. |
