| 中文摘要: |
| 赛都金矿位于阿尔泰山西段南缘克兰弧后盆地内,具有良好的成矿背景;玛尔卡库里断裂是金矿的控矿断裂,矿床的赋矿岩性为中泥盆统阿勒泰组海相杂砂岩建造;矿区内广泛发育一组低温热液蚀变,主要有绢云母化、绿泥石化、硅化、黄铁矿化、褐铁矿化及孔雀石化,围岩蚀变强度与构造变形强度成正消长关系;稳定同位素研究结果表明,金矿的成矿水源为大气水与岩浆水、变质水的混合水,硫主要源于地壳深部;相关地球化学数据表明,阿勒泰组上亚组地层为成矿的主要金质来源,该矿床属于受韧性剪切带控制的中低温热液型金矿。 |
| 英文摘要: |
| Saidu gold deposit is located in back arc basin at south margin of the west Altaishan mountain with favorable metallogenic background. Maerkakuli fault is the ore-control structure. The gold deposit occurs in marine greywacke of Middle Carboniferous Altai Formation. In the prospect are developed sericitization, chloritization, silicification, pyritization, limonitization and malachitization. The wall rock alteration intensity is proportion to the deformation intensity. Isotopic analysis shows that the ore fluid is a mixture of meteoric, magmatic and metamorphic water and sulfur from deep crust. Geochemically, Upper sub-formation of Altai Formation is the source bed. The gold deposit is a medium-low temperature one controlled by ductile shear zone. |
