Determination of Twelve Major and Minor Elements in Tourmaline by X-ray Fluorescence Spectrometry with Fusion Sample Preparation

Yankuang ceshi, 2018
Tourmaline is a class of boron-bearing aluminosilicate minerals. It has a complex chemical component and stable chemical property, and is difficult to decompose by wet methods. The high content of B2O3 makes it difficult to simultaneously determine major

Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

Boreas, Volume 55, Issue 2, Page 542-559, April 2026.
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.

Tourmaline ⁴⁰Ar/³⁹Ar chronology of tourmaline-rich rocks from Central Iberia dates the main Variscan deformation phases

Geologica Acta, 2009
During crustal thickening, metapelites taken to depth release boron-bearing hydrothermal fluids because of progressive heating and dehydration. These fluids swiftly percolate upwards, especially if the crust is being actively deformed, to form tourmaline

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

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 ...

Quantifying Multi‐Source Sediment Supply in a Tropical Foreland Basin (Oligocene‐Miocene Nyalau Formation, Borneo)

Basin Research, Volume 38, Issue 2, March/April 2026.
Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.
