北京平原目前尚未建立系统的地质剖面。1867年庞培莱将北京西山分为3大系,1871年李希霍芬提出震旦系、划分12层。1922年葛利普将震旦系限定在前寒武系,1923年田奇镌将南口剖面划分为7个岩组,1934年高振西将震旦系3分(南口群、蓟县群、青白口群)。1976年乔秀夫3分青白口群(下马岭组、龙山组和景儿峪组),1980年汪长庆等将十三陵剖面分为4系12组,1991版《北京市区域地质志》将十三陵剖面分为3系12组。本文初步建立平原区地层表,详细描述太古宙结晶基底和元古宙地层剖面,在京南大兴区的榆垡(兴热-1井)和安定(兴热-2井)发现太古宙片麻岩,在京热-70井、京热-59井、京热-71井和京热-75井编录蓟县纪地层,利用亦庄小学钻孔厘定待建系下马岭组、青白口纪龙山组和景儿峪组。
Beijing Plain has not yet established a systematic geological profile. In 1867, Pope Levin divided the Western Hills in Beijing into 3 major systems. In 1871, Richmond proposed the Sinian system and was divided into 12 layers. In 1922, Gelip restricted the Sinian to the Precambrian. In 1923, Tian Qi-Juan divided the south section into seven rock formations. In 1934, the high-amplitude west formed Sinian 3 (Nankou Group, Jixian Group, Qingbaikou Group). Qiao Xiufu 3 points in Qingbaikou group (Xiamaling Formation, Longshan Formation and Jing’eryu Formation) in 1976. Wang Changqing et al. Divided the Ming Tombs into 4 groups and 12 groups in 1980. In 1991, the “Beijing Regional Geological Records” Three hills section is divided into 3 groups of 12 groups. In this paper, a preliminary table of stratigraphy in the plain area is established. The Archean crystalline basement and Proterozoic stratigraphic sections are described in detail. Archean gneisses are found in the Yulong (Xingre-1 well) and Anding (Xingre-2) , Jiyang-Ji stratigraphy was recorded in Jijingzhuang-70 well, Jijingzheng-59 well, Jijingzheng-71 well and Jingzheng-75 well, and Yimazhuang primary school was drilled to determine Xiamaling Formation, Qingbaikouji Longshan Formation and Kingling Valley group.
