中文摘要：

阴山-燕山地区的大青山组／后城组／土城子组为巨厚的紫色粗碎屑岩沉积序列，时限为154-137Ma。燕山东部以安山质火山岩为主，燕山西部片麻岩和岩浆岩居多,阴山地区则主要为前寒武系变质岩。沉积物源（砾石）组分具有明显的地区性岩石组合特点。砂岩Qm—F—Lt图解显示其来源于再旋回造山物源区。不同地区古水流特征显示局地汇聚水流体系特征，暗示晚侏罗世-早白垩世华北北缘发育一系列相对独立的中小型盆地。沉积物碎屑锆石ICP—MSU-Pb定年结果表明，辽西土城子组具有115．2-144．2Ma、199．4-380．3Ma和1522-2629．1Ma3个年龄区间。阴山地区大青山组时代主要为1685-2325Ma，中侏罗统召沟组为1790．2-2471．2Ma,中上侏罗统长汉沟组为627．7-1971．2Ma和2003．9-2245．4Ma。燕山西部尚义后城组为206．7～371Ma．上侏罗统-下白垩统阎家窑组为225-364．7Ma和2643．9-2271．9Ma。辽西土城子组的物源主要来自燕山东部的二叠纪-三叠纪岩浆岩：尚义后城组和阎家窑组物源来自华北北部和兴蒙造山区晚古生代-早中生代岩浆岩及前寒武系；阴山地区召沟组-长汉沟组-大青山组物源来自阴山南麓前寒武系。辽西土城子组中发育基性（辉绿岩）岩脉和碱性岩体，大青山组／后城组／土城子组发育西向巨型风成砂（带）沉积（137Ma）等都指示了区域性伸展的构造背景。

英文摘要：

Daqingshan, Houchegn and Tuchengzi Formations distributed in Yinshan-Yanshan area consist of bedded purple coarse clastic sediments of great thickness and are constrained to about 154-137Ma. Sedimentary provenance composition （conglomerate） shows obvious localized rock assemblage features. Andesite is dominant in eastern Yanshan area, gneiss and magmatic rocks give priority to western Yanshan area, and Precambrian metamorphic rocks occupy the Yinshan area. Sandstone Qm-F-Lt diagram indicates a recycle orogenic provenance, whereas paleocurrent in different areas shows localized convergent river system characteristics, suggesting that a series of relatively independent middle-small scale basins were developed in northern North China during the Late Jurassic-Early Cretaceous period. Sedimentary detrital zircon ICP-MS U-Pb dating shows that the Tuchengzi Formation in western Liaoning,has three age ranges, i.e., 115.2-144.2Ma, 119.4-380.3Ma, and 1522-2629.1Ma, zircon ages of Daqingshan Formation in Yinshan area range from 1685 to 2325Ma, the Middle Jurassic Zhaogou Formation has ages of 1790.2-2471.2Ma, the Middle-Late Jurassic Changhangou Formation has ages of 627.7-1971.2Ma and 2003.9-2245.4Ma, Houcheng Formation in western Yanshan area ranges in age from 371Ma to 206.7Ma, and the Late Jurassic-Early Cretaceous Yanjiayao Formation has ages of 225-364.7Ma and 2643.9- 2271.9Ma. The provenance of Tuchengzi Formation in western Liaoning came from Permian-Triassic magmatic rocks of eastem Yanshan; Houcheng Formation and Yanjiayao Formation in Shangyi derived their materials from Late Paleozoic-Early Mesozoic magmatic rocks and Precambrian strata; Zhaogou Formation, Changhangou Formation and Daqingshan Formation were supplied by the Precambrian strata in southern Yinshan area. Rare 150-200Ma detrital zircon ages reveal that the underlying Tiaojishan Formation could not be the provenance of Tuchengzi Formation, and tectonic deformation or unconformity surface did not exist between Tuchengzi Formation and underlying Tia
