Late Cretaceous and Early Paleogene Fluid Circulation and Microbial Activity in Deep Fracture Networks of the Precambrian Basement of Western Greenland

Geochemistry, Geophysics, Geosystems
Deep fracture‐hosted fluids of Precambrian bedrock cratons are relatively stagnant over long time spans compared to near‐surface systems. However, episodic events, such as fracture reactivations, transgressions, and deglaciations, may introduce dilute ...

Constructing a Craton [PDF]

Science, 2010
Geophysics![Figure][1] CREDIT: USGS The cores of continents, or cratons, make up the stable lithosphere. Their formation probably occurred billions of years ago, though the mechanisms responsible remain unclear. One way to seek further insight is to look below the present-day continents for clues, such as where the lithosphere ends and the ...

Gawler Craton Uncovered

ASEG Extended Abstracts, 2004
The 2003 Gawler Seismic Survey acquired 250 km of 60-fold, deep seismic reflection data along two intersecting lines in order to investigate the crustal structure of the eastern Gawler Craton, South Australia. Seismic reflection data processing has produced images of the crust down to the Moho, through the overlying Neoproterozoic successions, the ...

Sedimentology and stratigraphic correlation of Vendian deposits in the southwestern Siberian Craton: Major contribution of an exocratonic clastic source to sedimentary systems

Литосфера, 2018
The study focuses on the sedimentation and stratigraphy of a large Vendian (Ediacaran) sedimentary basin in the southwestern Siberian craton, with implications for the origin of its units and subunits.

Chemical Significance and Chronology of Mesoproterozoic clastic rocks in Huainan Area

Chemical Engineering Transactions, 2018
After the 1.8Ga cracking event, the North China Craton entered the development stage of paraplatform, its southern margin, the Huainan area is in lack of accurate age data, so its stratigraphic sedimentation time limit has been controversial.

Formation and evolution of the Archean continental crust of China: A review

China Geology, 2018
: The mainland of China is composed of the North China Craton, the South China Craton, the Tarim Craton and other young orogenic belts. Amongst the three cratons, the North China Craton has been studied most and noted for its widely-distributed Archean ...
