宁夏贺家口子石膏矿矿床地质特征及成因探讨

Geological Characteristics and Genesis of Hejiakouzi Gypsum Deposit in Ningxia

石膏是宁夏的优势矿种之一,贺家口子石膏矿矿床位于同心~海原陆相盆地中,为一大型石膏矿床。本文以贺家口子一带石膏矿的地质勘查成果为依据,总结了成矿地质背景、矿床地质特征,并通过研究成矿物质来源、成矿古气候、古地理及成矿的物理化学过程等,对矿床成因进行了探讨,对今后在宁夏南部地质背景相似地区寻找同类型石膏矿床具有参考意义。

Gypsum is one of the dominant minerals in Ningxia, Hejiakouzi gypsum deposit is located in the Tongxin-Haiyuan continental facies basin, it is a large gypsum deposit. This paper based on the geological exploration results of gypsum deposit in Hejiakouzi area, this paper introduces the gypsum deposit in detail from the aspects of metallogenic geological background and geological characteristics, through the study of metallogenic material source, metallogenic paleoclimate, paleo-geography and metallogenic physical and chemical process, the genesis of the deposit is analyzed, it provides guidance for finding the same type of gypsum deposits in the south of Ningxia in the future.
