摘要
在前人研究工作的基础上,本文采用相关碎屑岩特征统计分析及运用G azzi-D ick inson三角图解方法对北大港东营组和沙河街组进行了碎屑岩类统计及物源分析研究,统计分析结果表明,研究区有多物源特性,物源来源于陆块物源区与岩浆弧物源区交接部位。自北向南沉积物稳定性与成熟度也有所提高,因此研究区物源也受到北部燕山物源的影响。
Based on studies of other people, Related clastic rock characteristic statistical analysis and utilizes the Gazzi -- Dickinson triangle graphic method were used in this article to study the provenance analysis for the shahejie Formation and the dongying Formation in Beidagang. The statistical analysis result indicated that the research area has the multi--source characteristic, the source originates from the landmass source area and the rock magma arc source area connection spot. From north to south the deposit stability and the maturity were improved, therefore the research area source also receives the influence of the northern of Yanshan source.
