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 ...

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.

The Neoproterozoic terranes of Saxony (Germany)

Precambrian Research, 1995
Abstract The Precambrian of Germany mainly outcrops in the states of Saxony and Thuringia. The Proterozoic units are surrounded by the Palaeozoic of the Saxo-Thuringian, which is one of the Hercynian fold belts. In Thuringia, the sedimentary record from the Neoproterozoic to the Hercynian flysch stage (Lower Carboniferous) is nearly completely ...

Neoproterozoic—Cambrian Biological Revolutions

The Paleontological Society Papers, 2004
The Neoproterozoic—Cambrian biological and geological events between 630 to 530 or so million years ago, are among the most fascinating topics in life history today because the first animals appeared and radiated amidst environmental changes of major magnitude.

Neoproterozoic Oxygen and The Rise of Animals

2017
This chapter considers the significance of the Ediacaran Fauna. Until the late 1980s, the Ediacaran Fauna were usually thought to represent ancient, primitive animal forms. Debate was sparked when leading paleontologist Dolf Seilacher from Tubingen, Germany, reinterpreted these fossils as something completely different.
