青海省茫崖镇大浪滩黑北凹地盆地钾矿区域水文地质特征分析

An Analysis of Hydrogeological Characteristics of Potassium Deposits in Heibei Depression Basin of Dayangtan,Yanya Town,Qinghai Province

青海省茫崖镇大浪滩盆地盐矿位于矿产资源丰富的柴达木盆地西北部,区域范围内绝大部分地区分布新生界地层,只在西北部阿尔金山地区有前新生界地层出露。区内沉积厚度较大,地质构造复杂,岩浆活动由加里东期至燕山期均有分布。针对大浪滩盆地盐矿区域水文地质特征分析探讨。

Yanlangtan Basin salt deposit in Yuya Town of Qinghai Province is located in the northwestern part of Qaidam Basin, which is rich in mineral resources. The vast area of the area is distributed in the Cenozoic strata.Only the pre-Cenozoic strata will be exposed in Altun Mountains in the northwest. The sedimentary thickness in the area is large and the geological structure is complex. The magmatic activity is distributed from Caledonian to Yanshanian. The hydrogeological characteristics of the salt mines in Dalangtan Basin are analyzed.
