山东诸城晚白垩世古地震事件与恐龙化石埋藏
Palaeoearthquake event and dinosaur fossil burial of the Late Cretaceous in Zhucheng of Shandong Province
摘要
Abstract
Various and complex styles of soft-sediment deformation structures were recognized in the Upper Cretaceous of the Kugou-Longgujian-Xijiantun district at southwestern area of Zhucheng in Jiaolai Basin, which was located in Jiaodong Peninsula, eastern China. Many types of brittle, plastic and lique fied soft-sediment deformation structures were found including load structure, ball-pillow structure, injec tion structure (flame structure), liquefied deformation, liquefied vein, mixed plunge structure, minor earthquake fault. These deformation structures were typically formed by coarse sediments during palaeo earthquake event. Multi-bed soft-sediment deformation interclated with non-deformed beds, which indicate the earthquakes of the Late Cretaceous in Zhucheng were frequent, multi-stage, periodic and of strong-weak changing. Large scale dinosaur ( hadrosaurs) fossils were found in coarse sediments from flood plain and debris flows were mainly from the Lower Cretaceous Laiyang and Qingshan Formations in the southern margin of the basin. Dinosaur fossils buried layer among the structural deformation layers of multi-layer palaeoearthquake soft-sediment deformation may be related with the sudden, strong energetic seismic events which lead to the mud-rock flow burying large scale dinosaur skeletons.关键词
