The Age of Coal-Bearing Strata in the Tuchengzi Coalmine District , Kangbao County , Hebei Province

辽西北票地区中&晚侏罗世土城子组恐龙足迹化石的发现

Discovery of Dinosaur Track Fossils from the Middle & Late Jurassic Tuchengzi Formation in the Chaoyang Area , Liaoning Province

辽西金-羊（金岭寺-羊山）盆地土城子组为一套红色陆相碎屑岩组合。

The Tuchengzi formation in Jinlingsi-Yangshan basin , Western Liaoning Province is composed of a series of red continental detrital rocks .

许多研究者认为该地区的土城子组与张家口之间存在着J3&K1界线和中生代的构造转换界面。

A lot of researchers think the boundary of the J_3-K_1 and the tectonic framework transition interface in Mesozoic Era in North Hebei-West Liaoning are located between the Tuchengzi and Zhangjiakou formations in the Luanping area .

根据岩石组合、组构、沉积相及环境变化等分析，本区土城子组自下而上大体可划分为1个Ⅱ级层序、2个Ⅲ级层序、26个Ⅳ级层序。

According to the rock association , fabrics , sedimentary facies and environment , the Tuchengzi Formation is broadly divisible in ascending order into one ⅱ - order sequence , two ⅲ - order sequences and26 ⅳ - order sequences .

这就表明了滦平地区的土城子组与张家口组是同一地质背景下的产物，即该地区二者之间应不存在J3&K1界面和构造转换界面。

The results imply that the Tuchengzi and Zhangjiakou formations were formed in the same geological background , and so are not the boundary of the J_3-K_1 and the tectonic framework transition interface between the Tuchengzi and Zhangjiakou formations in the Luanping area .
