The Anatomical Record, EarlyView.Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

The Anatomical Record, EarlyView.Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

IOP Conference Series: Earth and Environmental Science, 2022 Abstract Horizontal drilling and hydraulic fracturing can effectively increase the contact area between fractures and reservoir, which are important method to realize the economic and efficient development of unconventional reservoirs. In the traditional fracturing scheme design, “sweet spots” guide the fracturing construction.

Structural analysis of the eruptive fissures at Mount Etna (Italy)
Annals of Geophysics, 2011 Mount Etna produces frequent eruptions from its summit craters and from fissures on its flanks. The flank fissures trend approximately radially to the summit, and are mainly concentrated in three rift zones that are located on the NE, S and W flanks ...

The structural and diagenetic evolution of injected sandstones: examples from the Kimmeridgian of NE Scotland [PDF]
, 2003 : Injected sandstones occurring in the Kimmeridgian of NE Scotland along the bounding Great Glen and Helmsdale faults formed when basinal fluids moved upward along the fault zones, fluidizing Oxfordian sands encountered at shallow depth and injecting ...

Connectivity Evaluation of Fracture-Cavity Reservoirs in S91 Unit
Applied SciencesCarbonate fracture–cavity reservoirs are significant oil and gas reservoirs globally, and their efficient development is influenced by the connectivity between fracture–cavity units within the reservoir. These reservoirs primarily consist of large caves,
