| 摘 要： | 张家口地区是河北省金银多金属矿床集中区,本文划分出以宣化-崇礼-赤城一带岩浆-变质杂岩区为中心的金矿集中区和外围盖层区银多金属成矿分布区。幔枝构造研究表明,金银多金属成矿物质主要来自地球深部,通过地幔热柱多级演化向上迁移,并在幔枝构造的有利构造扩容带中集聚成矿。平面上从中心向外围,空间上,由下部往上部都具有金→银→铅锌的分带性,并已经在多处矿山得到研究证实。因此,张宣幔枝构造区深部仍有很大的找矿潜力。

| Abstract: | The Zhangjiakou area is the most important concentration region of gold-silver-polymetallic deposits in Hebei. This area is divided into the gold concentration area in the Xuanhua-Chongli-Chicheng magmatic and metamorphic complex,and the silver-polymetallic distribution area in the cover of the periphery. The mantle branch has shown that metallogenic material of gold,silver and so on was derived mainly from the depth,moved up through the multiple grade evolution of a mantle plume,and formed deposits in favo... |
