近年来,在我国东北南部辽、吉两省的早寒武世地层中相继找到了一些海积成因的(硬)石膏矿床。这一发现填补了东北地区一项急需的非金属矿资源的空白。成矿区域大地构造位置属天山-阴山东西纬向复杂构造带的东延部分,西起辽宁省辽阳、灯塔,东迄吉林省扶松、长白等地,为一长约350km、宽约60km的北东向槽状凹陷。按槽台 In recent years, some marine deposits of (hard) gypsum have been found in the Precambrian strata in Liao and Kyrgyz provinces of southern China. This finding fills the void of a much needed non-metallic mineral resource in the Northeast. The geotectonic location of the metallogenic region belongs to the eastward extension of the Tianshan-Yinshan zonal and zonal complex tectonic belt. It extends from Liaoyang in liaoning province to the lighthouse to the east to caisson and Changbai in Jilin Province to the east for a length of about 350km and a width of 60km North East Groove-shaped depression.
