Abstract: No research has been made on such a lower rank boundary as the Sinian Doushantuo Formation‐Dengying Formation boundary in the eastern region of the Yangtze Gorges. Elemental geochemical determination has revealed anomalies of REE and other trace elements around the boundary, which have relatively high contents than those in its overlying and ...

A Dynamic Classification Method of the Sinian Dengying Formation Heterogeneous Carbonate Reservoir
2020The Sinian Dengying Formation carbonate reservoir dominated by matrix pores and vugs in the Gaoshiti-Moxi area is characterized by strong heterogeneity. Such reservoirs with their tight matrix is identified as low-porosity and low-permeability, and yet with naturally-occurring fractures and dissolution vugs.

Abstract Tubular fossils are an abundant and diverse component of late Ediacaran benthic communities. However, with rare exceptions, their development and modes of asexualreproduction remain poorly resolved. With the deeper research and more specimens recovered, the types of asexual reproduction of tubular fossils are clarified.

Tectonic uplift at the end of Sinian resulted in the denudation of the Dengying (灯影) Formation on a different scale and the development of a great number of secondary dissolution vugs beneath the unconformity between Sinian and Cambrian. Geological and geochemical characteristics such as the development of caves, sinkholes, karst tubes and weathering ...
