| 摘 要： | 在川西前陆盆地蓬莱镇组层序特征研究基础上,将川西前陆盆地蓬莱镇组划分为5个沉积层序,每个沉积层序都由进积和退积体系域组成。以体系域为编图单元,采用体系域压缩法,编制了川西前陆盆地上侏罗统蓬莱镇组9张层序岩相古地理图。编图表明,川西前陆盆地蓬莱镇期古地理演化总体上显示盆扩/盆缩的特点,并具有明显的继承性、不均一性、阶段性和同步性。与传统的岩相古地理图相比,层序岩相古地理图具有动态、精确、等时、成因连续和勘探实用等优点。 |

| Abstract: | Based on sedimentary sequences,the Penglaizhen Formation in west Sichuan Foreland Basin is divided into five sedimentary sequences,each sequence consisting of a prograding and a retrograding system domain.Nine sequence based lithofacies and paleogeographic maps of Penglaizhen Formation in the western Sichuan Foreland Basin were recognized and used as mapping units.The results show that the paleogeographic evolution of the Penglaizhen Formation included multiple basin expansion and reduction phapses,earch sh... |
