在浙江省的南部,同福建省的山地相连。特点以低山为主,有些地方山势比较低洼,本区为史上岩浆活动频繁地区,形成多种非金属矿藏。非金属矿产资源丰富,其明矾石的储量居全国首位。对明矾石资源的开发利用也居全国前列;但对其的成因类型、控矿因素、成矿机理的研究相对滞后。通过综合分析浙江省南部地区典型矿床的地质特征、成矿条件与环境,将其分成:火山热液交代型、火山喷发沉积-热液交代型两种类型。
In the southern part of Zhejiang Province, it is linked to the mountains of Fujian Province. The main features are low mountains, and in some places the hilly areas are relatively low-lying areas. This area is characterized by frequent magmatic activities in the history and forms a variety of non-metallic mineral deposits. Non-metallic mineral rich in resources, its alunite reserves ranks first in the country. The development and utilization of alunite resources are also among the forefront of the country. However, their research on genetic types, ore-controlling factors and metallogenic mechanisms lags behind. Through comprehensive analysis of the geological characteristics, metallogenic conditions and environment of the typical deposits in the southern part of Zhejiang Province, it is divided into two types: volcanic hydrothermal replacement type and volcanic eruption-hydrothermal interchange type.
