Hydrocarbon Potential of the Late Permian and the Late Triassic Source Rocks from the Qamdo (Changdu) Basin, Eastern Tibet and Its Linkage with the Sea Level Change

Frontiers in Earth Science, 2021
The Qamdo Basin in eastern Tibet has significant petroleum potential and previous studies indicate that the basin contains thick potential source rocks of the Late Permian and the Late Triassic ages. In this paper, the petroleum potential of samples from

The Middle and Upper Permian Deposits in Gorski Kotar: Facts and Misconceptions

Geologia Croatica, 2010
The frequent occurrence of sandstones and other coarse-grainedsedimentary rocks in Gorski Kotar indicates molasse type sedimentationas a consequence of the intensive erosion of all uplifted terrain ina tectonically active area.

An abrupt extinction in the Middle Permian (Capitanian) of the Boreal Realm (Spitsbergen) and its link to anoxia and acidification [PDF]

, 2015
The controversial Capitanian (Middle Permian, 262 Ma) extinction event is only known from equatorial latitudes, and consequently its global extent is poorly resolved.

Upper Devonian to Permian

, 1997
The Upper Devonian and Carboniferous comprise a southern and a northern succession separated by the Ancestral Aklavik Arch. The southern succession, deposited in the Mackenzie Basin and the Prophet Trough, consists of Frasnian to Gzhelian strata. The northern succession comprises Viséan to Moscovian strata that onlapped the Yukon Fold Belt from the ...
