浙西江山地区三叶虫的埋藏规律探讨

研究化石的埋藏,可以重塑生物生活环境了解生物的生活方式、死亡原因以及这些生物在生活期间彼此的关系。寒武纪时浙西江山地区位于扬子地台南缘的陆棚斜坡地区,沉积了一套连续的深水斜坡相地层,保存了丰富的三叶虫化石。笔者采集了这一区域内荷塘组碎屑岩段与杨柳岗组、华严寺组灰岩段的三叶虫化石,并在室内进行了岩石切片观察,通过化石与沉积学相结合的研究,对这一地区当时的化石埋藏提出自己的见解、认识。

Discussion on Burial Patterns for Trilobite in Western Zhejiang Jiangshan Region

Study of the fossils,and remodeling can be buried biological living creatures for the cause of death and life,these creatures during the life of the relationship with each other.Cambrian western Zhejiang Jiangshan region is located in the Yangtze on the southern edge of the continental shelf slope area,the deposition of a continuous deep-water slope facies strata,save the rich trilobite fossils.The author has gathered in this region the lotus pond group clastic rock section and the willow hillock group,Hua Yansi the group calcareous rock section trilobita fossil,and has carried on the rock slice observation in the room,unifies the research through the fossil and the sedimentology,buried to this local fossil then proposes own opinion,the understanding.
