Evolution of ecological indicators in the assessment of restoration of mining‐degraded riparian forests: a global bibliometric analysis (1990–2024)

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of mining‐degraded riparian forests faces challenges due to structural, compositional, and functional impacts on these ecosystems. The demand for effective monitoring requires an understanding of how ecological indicators have been applied to assess post‐mining restoration success.

Tin‐Modified MXene Composite Electrodes as Lithiophilic Hosts for Stable Lithium Metal Anodes

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
A Sn‐modified Ti3C2Tx MXene host was developed to regulate lithium metal deposition by combining a lamellar porous architecture with Sn‐derived lithiophilic sites. Compared with bare Cu and pristine MXene, Sn@MX promotes more uniform and confined Li growth, suppresses dendritic deposition, and enables stable stripping/plating for over 120 cycles in ...

Accessory minerals and evolution of tin-bearing S-type granites in the western segment of the Gemeric Unit (Western Carpathians)

Geologica Carpathica, 2018
The S-type accessory mineral assemblage of zircon, monazite-(Ce), fluorapatite and tourmaline in the cupolas of Permian granites of the Gemeric Unit underwent compositional changes and increased variability and volume due to intensive volatile flux.

Cryptic Superfine Placer Gold Populations, Round Hill Mine, Southern New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Superfine (50–<1 µm) detrital gold and platinum group mineral (PGM) particles at the Round Hill mine near Foveaux Strait were locally derived (<20 km) from as‐yet undefined basement sources. This superfine component contrasts with the dominant coarser (typically >100 µm) gold and PGM particles at the mine that have been transported for >100 km in ...

Origin of colour zoning in cassiterites from tin deposits within the Bushveld Complex, South Africa [PDF]

Bulletin of the Geological Society of Finland, 1986
Cassiterites with striking colour zones from the syngenetic tin deposits at Zaaiplaats and from the epigenetic tin deposits at Rooiberg, Leeuwpoort and Union Mines, in the Central Transvaal, have been analysed by microprobe.

The Distinction Between Sn‐Mineralized and Sn‐Barren Granites in Sn Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Tin mineralization is commonly associated with highly evolved granites. However, not all highly evolved granitic rocks are mineralized with Sn. Comparative studies of Sn‐fertile and Sn‐barren granites can deepen our understanding of the key processes that lead to Sn enrichment in magmatic‐hydrothermal systems.
