新疆第四纪盐类矿产的形成和控制因素——兼论“高山深盆”成盐模式

根据袁见齐教授“高山深盆”成盐模式,探讨新疆天山对第四纪盐类矿床的形成和控制作用,阐述了天山地貌、气候、水文特征与盐类矿产的分布规律和特征。认为“高山深盆”并非一定是四周环山的深盆,可以是某一高山与其间深盆或两侧盆地的有机组合。高山的屏障作用造成了垂直的气候分带,在潮湿多雨的山区利于成盐组份的析出并迁移到干旱少雨的闭流深盆中,形成盐类矿床。

FORMATION AND CONTROLLING FACTORS OF QUATERNARY SALT DEPOSITS IN XINJIANG-CONCURRENT DISCUSSION OF "HIGH MOUNTAIN-DEEP BASIN" SALT FORMING MODEL

The "High Mountain -Deep Basin" salt -forming model,built by professor Yuan Jianqi,was applied in the study of formation,controlling factors,distribution and characteristics of Quaternary salt deposits, as well as morphologic, climatic, and hydrolpgic features in Tianshan. The "High Mountain - Deep Basin" is thought not to be necessarily the basin wholely surrounded by high mountains.it can be the basin within one mountain or at the two sides of a mountain. The vertical climatic zonation,caused by high mountain screen,is favourable for the separation of salt -forming components in the humid and rainy area,and for the migration of these components to the dry,little rainy and closed deep basins,resulting in the formation of salt deposits.
