凌源-宁宁城地区位于于燕辽沉降带东部(如图1),在中新元古界时期沉降缓缓慢、地层发发育齐全、厚厚度巨大,且变质质作用较小,,具有较好的的生烃潜力和和油气勘探价值。然而,该地地区中新元古古代地层被大大面积中生代地层层覆盖,地表表出露较少,,在中晚三叠叠世之后发生了强烈的构造变变形和大规模模的岩浆活动动,由缓慢的沉降过程转变为为强烈的东西西向构造变形形带-造山带。强强烈的构造变变形对早期地层层破坏严重,,给
The Lingning-Ningning-Cheng area is located in the east of the Yan-Liao subsidence belt (Fig. 1). During the Neoproterozoic period, the subsidence slowly and slowly, and the stratigraphic development is complete with a large thickness and a small change in quality. Good hydrocarbon generation potential and hydrocarbon exploration value. However, the Neoproterozoic strata in this area were covered by a large area of Mesozoic stratigraphy with less surface appearance. After the Late Triassic, strong tectonic deformation and large-scale magmatic activity occurred , From a slow subsidence process to the formation of a deformed belt-orogen for strong east-west. Severe structural deformation of the early formation of serious damage, to
