河北平泉地区高于庄组风暴沉积序列及沉积环境演变

THE TEMPESTITE SEQUENCES AND SEDIMENTARY ENVIRONMENTAL EVOLUTION OF THE GAOYUZHUANG FORMATION IN PINGQUAN,HEBEI

摘要: 河北平泉高于庄组发育三种类型的风暴岩,其岩石类型、沉积构造特征以及风暴沉积序列各不相同。它们是不同海水深度下风暴作用的产物。由此反映出高于庄组在沉积时经历了海进一海退的沉积旋回演变。

Abstract: The three types of tempestites.developed in the Gaoyuzhuang Formation,Pingquan, Hebei.are quite different each other in rock types,sedimentary structures and tempestite sequences.They are interpreted as the products of storm processes.at different depths of sea water,thus suggesting the sedimentary environmental evolution from marine incursion to regression in the study area during the deposition of the Gaoyuzhuang Formation.
