| 中文摘要: |
| 通过对小柳沟矿区成矿流体特征的研究认为,该区钨矿床成因是复杂多样的,其成矿流体是大气降水、海水和岩浆水的混合体,以海水为主,其成矿环境为弱酸性还原环境,推测矿床的形成为火山喷发沉积 后期岩浆热液叠加改造型矿床。 |
| 英文摘要: |
| Study of Xiaoliugou tunsten deposit indicates a complex genesis. The ore fluid is a mixture of meteoric water, sea water and magmatic water but dominated by sea water. The ore is formed under weak acidic condition. It is presumed that the deposit is a volcanic eruption sedimentary-late magmatic hydrothermal superimposed and reworked deposit. |
