摘要

南堡凹陷是在华北台地基底上,经中、新生代断块运动而发育起来的一个中新生界北断南超的箕状凹陷,其中火山岩岩性主要为玄武岩和凝灰岩。通过划分岩流单元和岩流组,并采用综合考虑爆发指数与厚度的方法进行岩相划分,确定研究区火山岩相以溢流相为主,爆发相主要集中于喷发中心附近,同时对研究区火山岩的平面、剖面分布作了研究,为下一步火山岩的储层研究提供了依据。

Abstract

Above the basement of North China platform, Nanpu Sag is a dustpan-like sag developed by fault-block movement during the Mesozoic and Cenozoic. The lithology of volcanic rocks is mainly composed of basalt and tuff. Based on the division of rock flow unit and rock flow group, explosive index and thickness are adopted to divide the lithofacies. The result shows that effusive facies is the main lithofacies in the study area, and outbreak is mainly concentrated in the vicinity of the eruption center. The distribution of volcanic rocks is studied, which provides basis for the further study on volcanic reservoir.
