根据大量煤田钻孔和地质填图资料,应用回剥技术分析研究了沁水盆地中北部的沉降史.结果表明,石炭-二叠纪以来,研究区主要经历了3期沉降和2期抬升:晚石炭世—中二叠世的缓慢沉降;晚二叠世—三叠纪的快速大幅沉降;罗纪—白垩纪,燕山运动引起的隆升剥蚀;新生代以来,受喜山运动影响的隆升剥蚀;新近纪—第四纪的快速沉降.自晚古生代以来,沉降中心大体由南向北迁移,东部抬升剥蚀量较西部大,最大剥蚀厚度超过1000 m.

Based on the data of drilling and geological mapping, the subsidence history of central-northern Qinshui basin is studied by the back-stripping technique in this paper. The study shows that this area experienced three stages of subsidence and two stages of uplift since Permo-Carboniferous period. Qinshui basin was subsided slowly from Late Carboniferous to Middle Permian and rapidly from Late Permian to Triassic period, uplifted and denuded from Jurassic period to Cretaceous because of Yanshan movement and since Cenozoic because of Himalayan movement, subsided rapidly from Neogene to Quaternary period. The subsidence center mainly migrated from the south to the north since late Paleozoic. The denudation in the east is more than that in the west and the largest de-nudation thickness is over 1 000 m.
