摘要
河北省滦县地区大红峪组为野鸡坨镇至响棠镇一带中元古界沉积盖层的最底部层位,这与滦县地区在元古宙地处山海关古陆边缘的地理构造格局有关。根据"岩相一层序一沉积环境"的研究思路与方法,将大红峪组地层划分为碎屑岩型和碳酸盐岩型两种相序,两个由TST-HST体系域构成的层序。沉积环境表现为东南侧为山海关古陆,北西侧为浅海台地,沉积作用初期以河流作用为主,进而发展为潮汐作用为主,偶为浅水风暴作用。
Dahongyu Formation is the bottom of the sedimentary cover of Mesoproterozoic in Luan County in Hebei Province, reflected as the edge of the proterozoic land is located in the Shanhaiguan ancient geography tectonic framework. According to “facies-sequence-the sedimentary environment” of the research idea and method, Dahongyu Formation was divided into clastic rock and carbonate rock type two kinds of phase sequence, two sequence composed of TST-HST system. Sedimentary environment of southeast of Shanhaiguan ancient land, northwest for offshore platform, the beginning of the sedimentation is given priority to with lfuvial, and for the development of tidal action, accidental is a shallow storm.
