我国脉石英成矿区带初步划分

Preliminary Division of Vein Quartz Metallogenic Belts in China

我国脉石英主要产于板块之间、造山带岩浆活动发育地区、区域变质作用强烈地区。脉石英主要分布于滨太平洋成矿域、秦祁昆成矿域,在古亚洲成矿域的新疆阿尔泰地区及伊犁地区有少量分布。本文在前人研究的基础上,结合近几年地质调查成果,共划分了东秦岭—大别、安徽旌德—青阳—浙江安吉、武功山—武夷山—赣南隆起、上扬子东部—龙门山—大巴山(陆缘坳陷)、东海—赣榆、鲁西隆起等16个脉石英成矿区带,并建立了与全国Ⅲ级成矿区带的对应关系。为今后非金属矿成矿区带划分及脉石英找矿勘查提供参考。

Vein quartz in China occurs mainly in areas where magmatic activity is developed between plates,tectonic orogenic belts,and areas with strong regional metamorphism.Vein quartz is mainly distributed in the coastal Pacific metallogenic domain and the Qinqikunmetallogenic domain,and a small amount is distributed in the Altai area of Xinjiang and the Yili area of the paleo-Asian metallogenic domain.Based on previous research and the latest survey results in recent years,this paper divides Eastern Qinling-Dabie,Jingde-Qingyang of Anhui-Anji of Zhejiang,Wugong mountain-Wuyi mountain-Jiangxi uplift,and eastern upper Yangtze-Longmen mountain-Daba mountain(continental depression),East China Sea-Ganyu,Luxi uplift and other 16 vein quartzs metallogenic belts,and have established a corresponding relationship with the national tertiary metallogenic belt.It provides a basis for the division of nonmetal metallogenic belts and vein quartz prospecting in the future.
