Prospects in Pre-Mesozoic Palaeomagnetism

Palaeomagnetism of the (Upper Palaeozoic-Lower Mesozoic) Pyongan Supergroup, Korea: a Phanerozoic Link with the North China Block

S U M M A R Y The Upper Carboniferous-Lower Triassic Pyongan Supergroup is exposed in an E-W trending syncline comprising the Samcheok Coalfield in eastern South Korea; it borders the southern margin of a NE-SW trending (Okcheon) zone of Upper Jurassic-Lower Cretaceous deformation (Daebo Orogeny). Although a Recent field overprint widely recorded in Korean rocks is represented here, an ancient ...

Pre-mesozoic palinspastic reconstruction of the eastern great basin (Western United States).

The Great Basin of the western United States has proven important for studies of Proterozoic and Paleozoic geology [2500 to 245 million years ago (Ma)] and has been central to the development of ideas about the mechanics of crustal shortening and extension. An understanding of the deformational history of this region during Mesozoic and Cenozoic time (245 Ma to the present) is required for pali...

The Mesozoic Lacustrine Revolution

The Mesozoic lacustrine revolution (MLR) represents a major evolutionary event in the continental realm (Cohen 2003 ). The decline in taxic diversity at the family level in lacustrine environments that took place during the late Paleozoic–Middle Triassic was reversed later in the Mesozoic, with diversifi cation seeming to have continued to the Quaternary, although potential biases may have affe...

Advancing Precambrian palaeomagnetism with the PALEOMAGIA and PINT(QPI) databases

State-of-the-art measurements of the direction and intensity of Earth's ancient magnetic field have made important contributions to our understanding of the geology and palaeogeography of Precambrian Earth. The PALEOMAGIA and PINT(QPI) databases provide thorough public collections of important palaeomagnetic data of this kind. They comprise more than 4,100 observations in total and have been es...
