| 摘 要： | 花岗斑岩型金矿床是微细粒浸染型金矿床的一种新亚类,广泛发育于扬子板块与秦岭造山带结合带上,矿床赋存于中泥盆统—中三叠统碎屑岩中的断裂带内,构造控制着岩浆及矿体的就位,花岗斑岩内构造的发育程度和蚀变强度决定了矿体的富集。通过对花岗斑岩和金矿床特征分析,初步建立了矿床的成因模式,总结了找矿标志。

| Abstract: | The Granite-porphyry type gold deposit is a new subgroup of microfine-dissemination type gold deposits,which devloped widespread in the integrate zone that the YangZi plate and the QingLing orogenic belt,the deposit situated on the fracture zone in the clastic rokes of the middle Devonian system-middle Triassic system,where magma and orebody are controlled by the structure,enrichment of bodies is controlled by degree of structural development and alteration.Based on characters of granite-porphyry and gold deposits,it is initially established the genesis mode of the deposit,and the sign to search for the deposit is summarized. |
