Tectonics, Volume 45, Issue 3, March 2026.Abstract The strength of the intracontinental lower crust exerts a primary control on regional‐scale deformation during continent‐continent collision. Because of the nominally anhydrous nature of much of the intracontinental lower crust, it is generally considered to be more viscous than lower crust in hydrated tectonic margins.

Possible petrogenetic associations among igneous components in North Massif soils: Evidence in 2-4 mm soil particles from 76503 [PDF]
Studies of Apollo 17 highland igneous rocks and clasts in breccias from the North and South Massifs have described magnesian troctolite, norite, anorthositic gabbro, dunite, spinel cataclasites, and granulitic lithologies that may have noritic anothosite

Tectonics, Volume 45, Issue 3, March 2026.Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

Moon's volcanic history revealed in glassy spherules from Apollo 17 soil 76501
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 389-404, March 2026.Abstract Rapidly quenched droplets of pyroclastically erupted lava are common in lunar regolith at landing sites proximal to the maria. Here, we document the U‐Pb chronologies, major element, and trace element compositions of picritic glassy particles from Apollo 17 regolith sample 76501. These particles are dominated by high‐Ti compositions similar to

Yankuang ceshi, 2016 A series of ultrabasic-acid igneous rocks are distributed in the belt of Urad houqi-Damaoqi-Siziwangqi, in middle Inner Mongolia. The formation age and geochemistry of these rocks can provide basic geological information for the metallogenic regularities

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

U–Pb geochronology and Hf isotope data from the Late Cretaceous Mawat ophiolite, NE Iraq
Heliyon, 2019 The Mawat ophiolite, NE Iraq, is one of the Neo-Tethyan ophiolites within the Iraqi Zagros orogen. It consists of many metre-to kilometre-sized tectonic slices of serpentinized dunite, peridotite, gabbro, basaltic rocks and associated oceanic ...

The Geologic Features of the Occurrence of Copper in North America [PDF]
, 1933 Copper is of such widespread natural occurrence in North America and there are so few metal-mining districts that have not contributed to its production that it is obviously necessary in any brief general treatment of the geology of the copper deposits ...
