浙东南主要非金属矿成矿特点与成因

本文讨论了浙东南地区 (江绍断裂以南 )高岭土、地开石、伊利石、叶蜡石、明矾石、沸石等非金属矿的产布、地质特征、成矿特点 ,认为多数系火山玻璃在构造火山～沉 (堆 )积盆 (洼 )地中成岩后 ,经大气降水、地下水水解改造 ,在燕山晚期的近地表氧化开放环境成矿 ;而萤石矿成因有与富氟花岗岩侵入作用及与大气降水和地下水改造作用有关两种充填类型。

Metallogenic Features and Genesis of the Main NonmetallicMineral Deposits in Southeast of Zhejiang Province

This paper discussed the distribution,geological features and metallogenic features of the non_metallic mineral deposits as Kaolin,dickite,illite,pyrophyllite,alunite and zeolite in southeastern areas of Zhejiang Province(south of Jiangshan_Shaoxing fault).It is considered that most of the mineral deposits were formed from volcanic glass in the tectonic volcano_sedimentary basin by precipitation and the hydrolysis of groundwater in the late Yanshanian Period,while the mineralization of fluorite had relations with the intrusion of fluorine_bearing granite or the precipitation and hydrolysis of groundwater.
