Limited and localized magmatism in the Central Atlantic Magmatic Province [PDF]

Nature Communications, 2020
AbstractThe Central Atlantic Magmatic Province (CAMP) is the most aerially extensive magmatic event in Earth’s history, but many questions remain about its origin, volume, and distribution. Despite many observations of CAMP magmatism near Earth’s surface, few constraints exist on CAMP intrusions at depth. Here we present detailed constraints on crustal

Water on Mars, With a Grain of Salt: Local Heat Anomalies Are Required for Basal Melting of Ice at the South Pole Today

Geophysical Research Letters, 2019
Recent analysis of radar data from the Mars Express spacecraft has interpreted bright subsurface radar reflections as indicators of local liquid water at the base of the south polar layered deposits (SPLD). However, the physical and geological conditions

Paleozoic Granitic Rocks from the Telmen Complex in the Tarvagatai Block, Central Mongolia: Petrogenesis, U-Pb geochronology, and its tectonic implications

Mongolian Geoscientist, 2023
The Tarvagatai Block is located in the northern part of Central Mongolia, which is a widespread occurrence and occupies roughly 60% of the whole exposure along the Khangai fault and the Tarvagatai uplift.

Petrography, Geochemistry and Tectonic Setting of the Harris Granite Body, Located in Mishu Mountains, Northwest of Iran (Shabestar City) [PDF]

پترولوژی, 2021
The Harris granitoid body, as a part of Alborz-Azarbaijan zone, located in the northwestern Iran and west of Shabestar city. The intrusive body cut the Kahar formation and covered by non-conformably Permian sediments. This body is granite- alkali granite

Petrogenesis, tectonic setting and geodynamic implications of keziergayin granites in the kelan basin (Chinese Altai): constraints from geochemistry, zircon U-Pb geochronology and Nd‒Hf‒Pb‒O isotopes

Frontiers in Earth Science, 2023
The Chinese Altai is characterized by abundant granitoids, which not only are indicators of the interaction between crust and mantle but also provide critical constraints on the tectonic evolution of the orogen. This study presents zircon U‒Pb‒O isotopes,

Partial magmatic bialgebras [PDF]

Homology, Homotopy and Applications, 2008
A partial magmatic bialgebra, (T;S)-magmatic bialgebra where T \subset S are subsets of the set of positive integers, is a vector space endowed with an n-ary operation for each n in S and an m-ary co-operation for each m in T satisfying some compatibility and unitary relations.

Margin-to-Margin Seafloor Spreading in the Eastern Gulf of Aden: A 16 Ma-Long History of Deformation and Magmatism from Seismic Reflection, Gravity and Magnetic Data

Frontiers in Earth Science, 2021
In this paper we present and analyze spreading-parallel seismic transects that image the oceanic crust in the eastern Gulf of Aden, from the Oman to the Socotra margins, across the active Sheba mid-oceanic ridge and between the Socotra-Hadbeen and ...
