| 摘 要： | 本文是朱碌科镇幅等两幅1：5万区调成果的一部分,通过分析盆地内的物质记录、火山岩特征、控盆构造,说明辽西地区中生代陆相沉积盆地的形成具有明显的旋回性,每一旋回均以强烈的火山喷发为先导,继而盆地沉降接受沉积.从早期到晚期,波罗赤盆地从西向东迁移.盆地早期形成于压性环境,晚期形成于拉张环境.波罗赤盆地形成时代为中侏罗世—晚白垩世早期.

| Abstract: | Based on the 1:50000regional geolo gical survey in Zhuluke-Boluochi sh eet,the basin-controlling structu re,sedimentary substances and volcani c rocks in Boluochi Basin are studied.By analyzing the volcanic materials,ter-rigenous clastic sediments and their sequence,the formation of Boluoch i Basin may be divided into three cycles.In each cycle,the sedimentary process begins with volcanic explosion,followe d by continental clastic deposition.The polycyclic formation of the basin is quite clear.The basin is in compression stress e nvironment in Middle Jurassic,and e xtension in Late Jurassic to Early Cretaceous.S imultaneously,the center of the Mesozoic basin transferred from the West(Zhongsanjia-Maozhengou)to East(Maozhengou-Huangdaoyingzi). |
