Destruction effect on Meso-Neoproterozoic oil-gas traps derived from Meso-Cenozoic deformation in the North China Craton

Precambrian Research, 2019
As the first extensively developed sedimentary cover in the North China Craton (NCC), the thick Meso- to Neoproterozoic strata have great exploration potential for hydrocarbons.

An overview of Neoproterozoic reservoirs in Pakistan

Geological Society, London, Special Publications, 2012
AbstractOver time, Neoproterozoic rocks in Pakistan have intermittently attracted the interest of oil and gas exploration companies. However, despite these rocks having been penetrated by nearly 40 wells and being exposed in various parts of Pakistan, no serious efforts have yet been made to investigate their reservoir potential.

Neoproterozoic-Cambrian microbialite record

The Paleontological Society Papers, 2004
Microbes and the sedimentary record of their activity, microbialites, have existed since the Archaean. During the Neoproterozoic-Cambrian interval, there is a marked shift in the fossil record of microbialites with the widespread proliferation of thrombolites (clotted microbialites) and the appearance and proliferation of dendrolites (microbialites ...

South China in Rodinia: Constrains from the Neoproterozoic Suixian volcano-sedimentary group of the South Qinling Belt

Precambrian Research, 2018
The South Qinling Belt, incorporating the northern margin of the Yangtze Block, South China Craton, records a series of Neoproterozoic to Triassic cycles of ocean opening and closing.

Neoproterozoic Acritarch Biostratigraphy of China

2020
According to studies of the acritarch biostratigraphy in China, the evolution of Neoproterozoic acritarchs roughly involves four stages, from older to younger, including the pre-Doushantuo Stage, the Doushantuo Stage, the Denying Stage and the Meishucun Stage.

Neoproterozoic banded iron formations

Lithology and Mineral Resources, 2009
Two epochs of the formation of ferruginous quartzites—Archean-Paleoproterozoic (3.2–1.8 Ga) and Neoproterozoic (0.85–0.7 Ga)—are distinguished in the Precambrian. They are incommensurable in scale: the Paleoproterozoic Kursk Group of the Kursk Magnetic Anomaly (KMA) extends over 1500 km, whereas the extension of Neoproterozoic banded iron formations ...

The Neoproterozoic Supercontinent: Rodinia or Palaeopangaea?

Earth and Planetary Science Letters, 2000
Abstract The Rodinia reconstruction of the Neoproterozoic Supercontinent has dominated discussion of the late Precambrian Earth for the past decade and originated from correlation of sedimentary successions between western North America and eastern Australia.
