Abstract
南华北马市坪盆地晚侏罗—早白垩世沉积厚度达989m，主要由辫状河沉积、三角洲沉积和滨浅湖沉积组成，根据岩性、沉积构造及遗迹化石的组成和产状特征，该文论述了河南马市坪盆地地区晚侏罗—早白垩世沉积环境中五种沉积类型和构造特征，划分了六个大的沉积旋回，并由此分析了该组沉积环境及演化历史。
North Southern China Ma Shiping the basin late dwarf Luo - early chalk world deposit thickness reaches 989m, mainly by the braided river deposition, the delta deposit and the shore shallow lake bed is composed, according to lothological, the sedimentary structure and the trace fossil composes with the occurrence characteristic, this article elaborated Henan Ma Shiping in the basin area late dwarf Luo - early chalk world environment of deposition five kind of deposition types and the structure characteristic, has divided six big depositional cycles, and has analyzed this group of environment of deposition and the evolved history from this.
