| 中文摘要: |
| 本文在综合前人资料和实际研究的基础上,认为熊耳群火山岩系是在1800～1400Ma的活动大陆边缘岛弧带形成的,具低金背景的特征,并指出其金成矿背景研究中存在的几个问题。 |
| 英文摘要: |
| Based on the synthesis of former information and practical research, the paper expounds that the volcanic rocks of Xionger Group formed in the island-arc of active continental margin during 1800～1400Ma, and has low An background values. Only stratigraphy method isn't enough to understand completely the primitive features and later deformation-metamorphism-alteration of Xionger Group; the Au arithmetic-average-values of volcanic rocks can' t represent the true state of gold contents of Xionger Group; the rock types determined only by petrochemistry are not proper nor is for determination of unimodel or bimodel distribution. It is suggested that the synthetic studies of geology,petrology-petrography and petrochemistry-geochemistry, such as lithologic charting, eruptive cycle analysing and volcanic mechanism building, determine the tectonic environment of volcanic emanation, rock types and diagenetic setting, and establish the areal gold contents and the gold contents of whole Xionger Group. |
