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 ...

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 ice ages and glacial sedimentary facies-areas in China
Precambrian Research, 1985Abstract Glacial rocks of the Sinian period are widespread in China. On the bases of stratigraphy and geochronology three Sinian ice ages can be discerned. In ascending order these are the Gucheng, Nantuo and Luoquan ice ages. The Gucheng and Nantuo ice ages are assigned to the Lower Sinian (740-700 Ma) and the Luoquan ice age is tentatively placed ...

Mechanism of Iodine Enrichment in Phosphorite of Late Sinian, SW China
Acta Geologica Sinica - English Edition, 2014Yangtze platform Doushantuoian is the first large-scale phosphorous forming peak period of China, and the sedimentary phosphorite is widely distributed in south China, at same time, this area have phosphorous deposits with abundant iodine element. Especially, the phosphorite occurred in the Doushantuo formation in the Late Ediacaran in Central Guizhou ...

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.

The Pre‐Sinian Basement and Mineralization on the Western Margin of the Yangtze Paraplatform
Acta Geologica Sinica - English Edition, 1990Abstract The pre‐Sinian basement on the southwestern margin of the Yangtze paraplatform consists of three metamorphic rock series of different ages. Being products of different tectonic events and environments, they differ markedly in original rock sequences, metamorphism, tectonic style and characteristics of granitoids and mineral deposits.

Geological models of ice keel scours, with an early sinian example
Precambrian Research, 1992Abstract Ice-keel turbate is widespread on recent continental shelves. The surface morphology of modern ice keel scours is well-known but their subsurface structures are not well studied. In the geological record ice keel scours are rare and no data on their subsurface structures from pre-Pleistocene glacial sediments exist.
