| 中文摘要: |
| 陕西省凤太矿集区是我国重要的金、铅锌矿产资源地,区内八卦庙金矿存在微细浸染型、脆－韧性剪切带型以及造山型等成因分歧。通过对区内八卦庙金矿床和花红树坪岩体、西坝岩体时空关系、地球化学、稳定同位素等的综合研究,认为凤太矿集区金矿成矿与高Sr低Y埃达克质岩石具有时间、空间、成因方面的密切联系。结合区域金矿成矿资料,高Sr低Y埃达克质岩石显示出金矿成矿的专属性特征,这为认识凤太矿集区金矿成因及成矿预测提供新的思路。 |
| 英文摘要: |
| Fengtai ore-concentrated area in Shaanxi Province is an important mineral resource area of gold, lead and zinc in China. There is a controversy on origins of Baguamiao gold deposit in this area, like finely disseminated type, includes shear zone type and orogenic type. Through comprehensive researches on the time-spatial relationship, geochemistry and stable isotopes of Baguamiao gold deposit, Huahongshuping pluton and Xiba pluton in Fengtai area, it is concluded that there is a close relationship between gold mineralization in Fengtai ore-concentrated and high Sr-low Y adakitic rocks in time, space and origin. Combined with the regional gold mineralization data, the gold metallogenic specialization of adakite can be shown, that provides a new idea for the study on the origin of gold deposit and metallogenic prognosis in Fengtai ore-concentrated area. |
