| 摘 要： | 大安河金矿床是黑龙江省典型的夕卡岩型金矿床,但有关该矿床成矿岩体的地球化学及成矿动力学尚缺乏研究和报道.选取与成矿密切相关的辉长岩开展相关研究,结果表明,辉长岩为富铝质岩石,富集大离子亲石元素(LILE),相对亏损高场强元素(HFSE);岩浆起源为富集地幔与大陆地壳的混合,而且以富集地幔为主;成岩成矿机制与佳木斯与松嫩地块的拼合和侏罗纪太平洋板块的俯冲关系密切.

| Abstract: | The Da＇anhe gold deposit in Heilongjiang Province is a typical skarn deposit. However, there was rare research on geochemistry and metallogenic dynamics of the ore-forming rock mass of the deposit previously. This study focuses on the gabbro that is closely related to mineralization. The result shows that the gabbro is Al-rich rock, with enrichment of large-ion lithophile elements （LILE） and depletion of high field strength elements （HFSE）. The origin of magma is the mixture of main enriched mantle and continental crust. The diagenetic-mineralization mechanism is closely related to the amalgamation of Jiamusi and Songnen massifs and the subduction of Jurassic Pacific Plate. |
