Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The Nanga Parbat–Haramosh Massif located in the northwestern syntaxis of the Himalaya is an antiformal structure considered as a crustal diapir undergoing exhumation at a rate larger than 10 mm/yr since 1 Ma. Using GNSS horizontal surface velocities and a vertical and east–west decomposition of the Sentinel‐1 interferometric line‐of‐sight ...

The Tibet leucogranite as a potential high-purity-quartz raw material: first discovery and case study from the Dinggye area [PDF]
European Journal of MineralogyThis study evaluates Tibet leucogranites as a potential raw material for high-purity quartz. We systematically investigate the petrography, geochemistry, and purification potential of leucogranites from the Ama Drime Massif of the Dinggye area.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The role of sub‐arc mantle lithosphere in the build‐up of a batholith is an outstanding issue that is still not well resolved. Lamproite is a mantle‐derived magmatic rock that provides a window to learn the composition and the enrichment processes of subcontinental lithospheric mantle (SCLM).

Petrography and Geochemistry of tourmaline nodules from Aderba leucogranite (northeast of Golpaygan) [PDF]
پترولوژی, 2016 The Aderba leucogranite in the Golpayegan metamorphic core complex (GMC), a part of Sanandaj-Sirjan zone, host lentiform small (2*4 cm)(Type 1) and large (7*14 cm)(Type 2)tourmaline nodules. In terms of mineralogical features, the core of these two types

Growth and Chemical Evolution of the Kohistan Arc Crust, Northern Pakistan, Western Himalayas
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Fossil arcs which expose the middle‐lower crust have the potential to shed light on active arc processes because magmatic rocks from the entire history of the arc can be examined. We present new geochemical data from the middle crust of the Kohistan Arc and use existing geochemical and geochronological literature data from this arc to ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.
