摘　　要：对华北陆块北缘化德—康保一带化德岩群浅变质岩野外宏观特征、岩石组合类型、变余结构构造等进行判定,并结合岩相学、地球化学以及图解判别法研究表明,其原岩为一套砂泥质—碳酸盐岩组成的类复理石建造,沉积环境总体为潮坪—潮下—开阔海(浅海)沉积。The field macroscopic characteristics,rock assemblage types,residual structure and structure of the shallow metamorphic rocks of the Huade Group in the northern margin of the North China Block are judged,and combined with petrography,geochemistry,and graphic identification methods,it is shown that the original rock is a set of flysch-like structures composed of sandy argillaceous-carbonate rock and the depositional environment of the Huade Group is generally tidal flat-subtidal-open sea(shallow sea)deposition.
