Relationships Between Lithospheric Structures and Rifting in the East African Rift System: A Rayleigh Wave Tomography Study

Geochemistry, Geophysics, Geosystems, 2018
The East African Rift System (EARS) provides a unique location for exploring factors influencing the development and maturation of continental rifting.

Lithospheric and crustal thinning [PDF]

In rift zones, both the crust and the lithosphere get thinner. The amplitude and the mechanism of these two thinning situations are different. The lithospheric thinning is a thermal phenomenon produced by an asthenospherical uprising under the rift zone.

The chemically zoned 1949 eruption on La Palma (Canary Islands): Petrologic evolution and magma supply dynamics of a rift zone eruption [PDF]

, 2000
The 1949 rift zone eruption along the Cumbre Vieja ridge on La Palma involved three eruptive centers, 3 km spaced apart, and was chemically and mineralogically zoned.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

GRAVITY VARIATIONS AND RECENT GEODYNAMICS OF THE SOUTH-WESTERN PART OF THE BAIKAL REGION

Геодинамика и тектонофизика, 2015
Modern methods for determination of gravity values make it possible to obtain measurements with the accuracy up to 10–9 from g0 of the normal value (up to 1 microgal = 10 m/sec2).

Contrasting stress fields on correlating margins of the South Atlantic [PDF]

, 2015
The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

Journal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.
