Rapid Incorporation of Metasediments Into Lower Crust of the Gangdese Magmatic Arc, Southern Tibet

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Deeply exhumed crustal terranes of continental arcs worldwide commonly contain metasedimentary components, but the nature of these lithologies and how they became incorporated into the lower crust are not fully understood. Here, we present petrological, geochemical and geochronological data from exhumed deep‐crustal metapelites and ...

Facies and Depositional Environment Analysis of Alternate Channel Bodies in the Flank of a Sag Structure [PDF]

, 2015
The down-dip (40o) portion turbidite Cenozoic deposits of the western sag structure in the Bohai bay been characterized for stratigraphy. Laterally tracking continuity in temporal data becomes challenging with increase in offset. In achieving this and

Volcanic Facies From Probabilistic Multi‐Physics Characterization of an Andesite Island Volcano, Whakaari/White Island, New Zealand

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Collapse of hydrothermally weakened rock on the flanks of volcanic islands is a recognized cause of tsunamis generated by volcanoes. Here we use a multiphysics clustering method to derive a volcanic facies model for Whakaari/White Island, an andesite arc volcanic island in New Zealand.

Quantitative reservoir evaluation and hydrocarbon volumetrics :an integrated petrophysical and 3-D static modeling approach in ‘Hamphidex’ field, Niger-Delta, Nigeria

Journal of Nigerian Society of Physical Sciences
The viability and hydrocarbon volumetrics of the Hamphidex field reservoirs were evaluated using petrophysical analysis and three-dimensional (3D) static modeling of three key reservoir sands (X, Y, and Z).

Formation evaluation and reservoir characteristics of the Messinian Abu Madi sandstones in Faraskour Gas Field, onshore Nile Delta, Egypt

Journal of Petroleum Exploration and Production Technology, 2020
The Messinian Abu Madi Formation represents the most prospective reservoir target in the Nile Delta. Hydrocarbon exploration endeavors in Nile Delta over the last few decades highlighted some uncertainties related to the predictability and distribution ...

Miocene reservoir rocks: pore throat size distribution as a strong controller on petrophysical attributes is a reflection of facies change

Journal of Petroleum Exploration and Production Technology, 2018
Pore throat size distribution (PSD) is considered a finger print for each rock type and has strong effects on many petrophysical parameters, so a comparative study was done on irregular subsurface rock samples that belong to Kareem and Rudeis Formations ...

The Inter‐Cratonic Neoproterozoic Katangan Basin of Central Africa: Rift Basin Formation, Orogenic Inversion and Potential Fluid Pathways

Tectonics, Volume 44, Issue 7, July 2025.
Abstract The tectono‐stratigraphic development of continental basins is critical to an understanding of continental tectonics and the formation of metal deposits. The Neoproterozoic, inter‐cratonic Katangan copper basin of Central Africa records a tectono‐stratigraphic evolution and the generation of potential metal transporting fluid pathways ...
