Summary: Cretaceous basins in NE Asia were formed from different types of continental rifting in disparate regions, influenced by differential subduction and slab tearing of the western paleo-Pacific plate. The different types of rift basins, including passive, active, and wide rift basins, developed in different regions due to crustal stretching, asthenospheric upwelling, and lithospheric-scale tear fault. The Late Cretaceous period in NE Asia witnessed mild deformation and weak magmatism, possibly caused by kinematic variation of the paleo-Pacific plate.

Summary: This study reveals the vertical variation in organic matter enrichment of the Upper Permian Dalong Formation in the northern Sichuan Basin, which was related to the expansion of the Paleo-Tethys Ocean induced transgression and upwelling in the northern continental margin of the Upper Yangtze. The differences in types and strength of the upwelling result in the variation of paleoproductivity and redox conditions, and thus the organic matter abundance in the sedimentary rocks.

Summary: The only known natural samples of high-pressure mantle constituents are mineral inclusions in diamonds, and their origin and formation have been a subject of debate. By analyzing trace elements in olivine crystals from South Africa, researchers have found evidence suggesting that these crystals formed in the deep upper mantle and potentially in the mantle transition zone. These findings provide insights into Earth's early mantle evolution and the formation of ancient continental and oceanic crust.

Summary: The Proterozoic Vindhyan Basin in central India provides insights into the surface conditions of the early Earth. Geochemical and isotopic analysis of sedimentary rocks from two sub-basins, CVV and SVV, suggest a common provenance and connectivity during the deposition of the Vindhyan sediments. The shift in Nd isotopic compositions around 1.6 Ga may be attributed to Andean-type arc magmatism near the Son Valley sub-basin.

Summary: This study evaluates the geochemical and petrographic characteristics of bituminite shales from the Kapurdi mine in Rajasthan, NW India to determine their organic matter inputs and oil-prone potentials. The high total organic carbon (TOC) content and low total sulfur content suggest a fresh lacustrine environment for the deposition of these bituminite shales. The presence of Botryococcus algae confirms the dominance of a lacustrine setting. The organic matter inputs and environmental conditions indicate the potential for both oil and gas generation.

Summary: Twenty-one gastropod species have been identified in the Cenomanian deposits of Bellezma-Aures mountains, eastern Saharan Atlas, Algeria, with four of them recorded for the first time in the Batna mountains. These gastropods are mainly found in the 'Marnes de Smail' Formation, and their community changes may be attributed to minor sea-level fluctuations, sedimentation rate variations, and hydrodynamics. The paleobiogeographic distribution of these gastropod assemblages indicates a tethyan affinity and faunal exchange during that time interval.
