摘　　要：为了进一步查明黄浒膨润土矿地质特征,本文以该矿区Ⅰ号矿体为研究对象,开展了地质测量、钻探、化学测试及利用软件模拟等方法,对矿区控矿地质条件及其地质特征进行了分析。研究表明:该矿床是以白垩系蝌蚪山组安山质角砾凝灰岩及安山质角砾熔岩为成矿原岩,经过低温热液蚀变及表生氧化作用形成的火山沉积型膨润土矿床。本次研究工作为后续寻找火山沉积型膨润土矿床提供了找矿思路与经验。Focusing on the ore body I of the Huanghu bentonite deposit,this paper has conducted geological surveying,drilling,chemical testing and software simulation to analyze the ore-controlling geological conditions and their characteristics.The results indicate that this is a volcanic sedimentary bentonite deposit formed by low-temperature hydrothermal alteration and supergene oxidation on the basis of the primary rocks of andesitic brecciated tuff and andesitic brecciated lava of the Cretaceous Kedoushan Formation.This study provides a train of thought and experience for search of volcanic sedimentary bentonite deposits in the future.
