Abstract
The Hari Depression is located in the northern part of the Yin'e Basin and is a highly enclosed intracontinental faulted lake basin with an area of approximately 1500km2.This article explores the genesis,mineralization types,ore controlling factors,and distribution patterns of the natural alkali deposit in the Hari Depression through the study of its geological characteristics,ore controlling structural mechanisms,and diagenetic mineralization ages.Research has shown that the structural evolution of the Hari Depression has gone through two main stages:the formation of the Paleozoic basement and the development of the Mesozoic depression.The northeast oriented high angle normal faults developed within the depression control the morphology and distribution of the lake basin.The formation of mineral deposits is controlled by closed lake basins,arid semi-arid climatic conditions,and sodium rich carbonate brine environments.The rocks around the basin,which are rich in sodium and poor in calcium and magnesium,provide a material source for mineralization.The research results provide important theoretical basis for further exploration and resource.关键词
