湖南早震旦世沉积建造浊流沉积及锰矿成因

主要从沉积建造角度讨论了各种不同构造古地理、古生物、古环境、地球化学及同位素地质，对早震旦世锰矿成矿的控制。并且把湖南早震旦世地层划分出五个沉积建造系列；恢复了湖南省早震旦世大地构造－沉积建造理想剖面，另一方面，对早震旦世地层的形成，提出了＂浊流成因＂的新认识，初步阐述了浊流产生的动力条件。最后提出了＂多源、生物－浊流沉积成矿模式＂。

EARLY SINIAN SEDIMENTARY FORMATIONS,TURBIDITE AND MANGANESE ORE GENESIS IN HUNAN PROVINCE

In this paper the author has discussed, from an angle of sedimentary formation, the control of tectonic setting, paleogeographical conditions, paleobiota, paleoenvironment, geochemistry and isotope geology over manganese ore genesis. The Lower Sinian of Hunan Province has been divided into five sedimentary formation series and an ideal cross-section showing the Early Sinian tectonics and sedimentary formation of hunan Province has been restored. On the other hand, the author has proposed a new understanding of the formation of the Lower Sinian, the "turbidity current" origin, and has preliminarily elaborated the dynamic conditions of occurrence of turbidity current.Finally the author has proposed a multisource, biotic-turbidity current deposition model for manganese ore formation.
