3.08 billion-year-old crustal differentiation constrained by Sn and O isotopes of detrital cassiterite

open access: yesCommunications Earth & Environment
Formation of granite-hosted tin deposits reflects the differentiation and maturation of continental crust. While rare in Earth’s early continental crust, the eastern Kaapvaal Craton in southern Africa may harbor the oldest known tin-bearing granites ...

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

open access: yesJournal 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.

Experimental Study on Recovering Fine Cassiterite from Spontaneously Combusted Dachang Cassiterite-Polymetallic Sulphides

open access: yes, 2011
Fine polymetallic sulphides in Dachang mining areas are very difficult to be recovered. In order to solve this problem, a new flowsheet of jet centrifugal concentrator separation-flotation-tabling separation was adopted in this study, which means that ...

Enhanced Flotation Separation of Cassiterite from Calcite Using Metal-Inorganic Complex Depressant

open access: yes, 2021
At present, the research on flotation separation of cassiterite and gangue minerals is mainly focused on the development of new collectors or depressants, while the research on combined depressants is rare.

Petrogenesis and tectonic-magmatic context of emplacement of lepidolite and petalite pegmatites from the Fregeneda-Almendra field (Variscan Central Iberian Zone): clues from Nb-Ta-Sn oxide U-Pb geochronology and mineral geochemistry

open access: yesBSGF - Earth Sciences Bulletin
The Fregeneda-Almendra pegmatite field of the Iberian Massif represents a typical expression of peraluminous rare-metal magmatism that occurred over western Europe at the end of the Variscan orogeny.
