Conglomerate reservoir is an important part of unconventional oil and gas resources, which has great developmental potential. However, its sedimentary environment structural background are complex, cementation types, gravel volume fraction shape quite different, leads to strong heterogeneity. When developing a conglomerate reservoir, it extremely difficult drill because It obtain the mechanical...

The granularity distribution of mine dump materials has received extensive attention as an essential research basis for stability and land reclamation. Image analysis is widely used the fastest most efficient method to obtain materials. This article proposes a deep learning-based approach detection identification material, conglomerate, clay. Firstly, Conglomerate Clay Dataset (CCD) proposed st...

STM brings to light chirality aspects of the self-assembly of a functionalized helicene at the interface between a liquid and the solid substrates, gold and graphite. This reveals conditions for conglomerate formation.

Cenozoic volcanic activity in Morocco started the Miocene and proceeded, after a short break, during Pliocene Quaternary. Calc-alkaline magmatic occurred first was accompanied by eruption of transitional lavas, followed Plio-Quaternary alkali basaltic activity, which emplaced within Neogene sedimentary basins Rif belt its foreland. From calc-alkaline to alkaline magmatism, passing through term,...

Forty eight years have elapsed since formal discussions were initiated, in 1948, on the position of the PlioPleistocene boundary. At the 18th International Geological Congress held in London during that year the Commission on the Plio-Pleistocene boundary recommended that “the Lower Pleistocene should include as its basal member the marine Calabrian Formation together with its terrestrial (cont...

Archaeological data are frequently cited in support of the idea that big game hunting drove the evolution of early Homo, mainly through its role in offspring provisioning. This argument has been disputed on two grounds: (1) ethnographic observations on modern foragers show that although hunting may contribute a large fraction of the overall diet, it is an unreliable day-to-day food source, purs...
