Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Efficiency of singularity and PCA mapping of mineralization-related geochemical anomalies: a comparative study using BLEG and <180μm stream sediment geochemical data

Bulletin of the Mineral Research and Exploration, 2022
In gold (Au) exploration, the analysis of both bulk leach extractable gold (BLEG) and acid-extractable Au in the <180μm stream sediment fraction are the two most common approaches.

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 ...
