西藏改则地区班公湖-怒江结合带内上三叠统的发现及其地质意义
The discovery of the Upper Triassic strata in Bangong CoNujiang junction zone of Gerze area in Tibet and its significance
摘要
Abstract
There exist only very few outcrops of Triassic strata on both sides of the Bangong Co-Nujiang junction zone. Early Trias-sic period was the beginning of the initial evolution of the Nujiang Ocean basin. The large- scale continuous marine regression and crustal uplift caused the denudation of the strata; hence the whole Bangong Co-Nujiang junction zone lacks a complete Triassic strati-graphic system, and there exists no complete material record for the study of the evolution of the Nujiang Ocean. The discovery of the Triassic strata based on fossils provides an ideal basis for the study of the evolution of the Nujiang Ocean basin, and also supplies basic data to regional stratigraphic correlation, establishment of stratigraphic framework and paleoenvironment analysis.关键词
