On the upper Precambrian (Sinian Suberathem) in China
Precambrian Research, 1981Abstract This paper gives a general outline of the Upper Precambrian (Sinian Suberathem) in China, including its geographic distribution, development, stratigraphic sequence and classification. The Sinian Suberathem, with a time range of 1950-615 Ma, constitutes the greater part of the Proterozoic.

Integrated Ediacaran (Sinian) chronostratigraphy of South China
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007Abstract The Ediacaran Period was a critical time in the history of life and Earth. Understanding the complex interactions between geological and biological events during this interval requires high-resolution chronostratigraphy. Thanks to its uniquely favorable palaeogeographic setting, South China is an ideal region for constructing a framework for

Geochemical Characteristics of Sinian Manganese Deposits in China
Acta Geologica Sinica - English Edition, 2000Abstract Sinian is one of the main periods of the formation of manganese deposits in China. Sinian manganese deposits are mainly hosted in carbon‐rich black shale and siliceous shale formed during the Sinian interglacial period. The composition of manganese ore is simple. The main ore mineral is manganiferous carbonates.

The Sinian microfossils from Jinning, Yunnan, south west China
Precambrian Research, 1983Abstract A microfossil assemblage has been detected in phosphorite cherts from the Dengying and Meishucun Formations (610 Ma) of the Sinian System in Jinning County, Yunnan Province, southwest China. A unique type (mode) of microfossil preservation — collophanite or apatite, or even in rare cases, chert-replacement — is reported here for the first ...

Sinian microfossils from south-west China
Nature, 1981The microfossil assemblages described here are preserved in cherts from the Yunnan Province, south-west China. They are the first chert-facies microfossils to be discovered in the Wangjiawan and Meishucun stratigraphical sequences which are regarded by the International Cambrian/Precambrian Boundary Working Group1 as possible ‘candidates’ for the ...

Biomarkers of Upper Sinian cyanobacterial dolostones in southwest China
Journal of Southeast Asian Earth Sciences, 1991Abstract In the present paper, eight core samples of cyanobacterial dolostone from the Dengying Formation (Sinian) of the Weiyuan Gas Field, Sichuan, southwest China, have been studied organically and geochemically. It has been shown that the following biomarker compound exist.

Ediacaran seawater temperature: Evidence from inclusions of Sinian halite
Precambrian Research, 2011Abstract Seawater temperatures throughout Earth's history have been suggested to illustrate a long-term cooling trend from nearly 70 °C at ∼3500 Ma to around 20 °C at ∼800 Ma. The terminal Neoproterozoic prior to the “Cambrian Explosion” is a key interval in evolutionary history, as complex multicellularity appeared with the advent of the Ediacara ...

Abstract Despite the complete sequence and widespread distribution of diversified Sinian sediments within China, the research on Sinian metazoan fossils in China has been a weak link all along, which partly hinders the study of the Sinian system.

Sinian paleomagnetic results from the Tarim block, western China
Precambrian Research, 1991Abstract A Sinian (latest Precambrian) section composed of shallow marine carbonates, nonmarine clastics, tillites and minor volcanic rocks, is exposed in Wushi, along the northwestern margin of the Tarim block of China. Paleomagnetic results from this section reveal at least six geomagnetic field reversals.

Precambrian microfossils from the Sinian of South China
Nature, 1981The discovery of previously unknown microfossils from the Sinian of western Hubei Province, South China (Fig. 1) is reported here. The Sinian there, up to 1,000 m thick, is naturally divisible into four formations (Fig. 2) from the base upwards: (1) the Liantuo Formation comprising feldspar–quartz–sandstones with basal conglomerates; (2) the Nantuo ...
