北京十三陵元古宙大红峪组在不足 4km的距离内岩相急剧变化 ,实为国内外罕见。从东至西 ,泰陵剖面由灰色角砾硅化岩 +黑色粉砂凝灰页岩 +黄色含长石石英砂岩组成 ,山顶剖面由不纯砂岩 +泥质白云岩组成 ,德胜口剖面由泥质白云岩 +石英砂岩 +层凝灰岩组成。本文仅对泰陵剖面大红峪组的三种岩石进行系统研究。宏观、微观特征、地球化学和同位素地球化学分析数据表明 :泰陵剖面大红峪组的灰色角砾硅化岩和黑色粉砂凝灰页岩是受火山 -地震事件影响形成的沉积岩 ,而覆盖其上的黄色含长石石英砂岩形成于正常滨海环境中。最后提出大红峪组含事件信息的沉积岩形成模式图。
The Paleolithic Dahongyu Formation of the Ming Tombs in Beijing changed dramatically in less than 4km distance, which is rare at home and abroad. From east to west, the Tailing section is composed of gray brecciated silicified rock, black silty tuff shale and yellow feldspathic quartz sandstone, the top section of which is composed of impure sandstone + dolomite, and the Deshengkou section consists of mud Quality dolomite + quartz sandstone + tuff composition. In this paper, only three types of rocks in the Dahongyu Formation in the Talingling area are systematically studied. The data of macroscopic, microscopic, geochemical and isotope geochemical analysis show that the gray brecciated silicified rock and black silty tuffaceous shale in Dahongyu Formation of Talingling Section are sedimentary rocks formed by the volcano-seismic event, The yellow feldspar quartz sandstone formed in the normal coastal environment. In the end, the formation pattern of sedimentary rocks with event information in Dahongyu Formation is proposed.
