Baogutu: An example of reduced porphyry Cu deposit in western Junggar
Ore Geology Reviews, 2014 Abstract Classic oxidized porphyry copper deposits (OPCD) are characterized by high tonnage and elevated f O 2 and contain highly oxidized minerals including primary anhydrite and hematite. In contrast, the Baogutu deposit contains abundant hypogene pyrrhotite and methane-rich fluid inclusions, characteristic of lower tonnage, reduced porphyry ...

Motion Sensitivity Analysis and Terrain Correction for UAV‐Borne Gamma‐Ray Spectrometry
Geophysical Prospecting, Volume 74, Issue 7, September 2026.ABSTRACT Uncrewed aerial vehicles (UAVs) equipped with gamma‐ray spectrometry sensors enable high‐resolution surveys but face challenges in rugged terrain. Conventional airborne gamma‐ray processing commonly approximates the source–detector geometry using a single height‐above‐ground parameter.

Evaluating Fragmentation Detection in Block Caves Using Synthetic Muon Tomography
Geophysical Prospecting, Volume 74, Issue 7, September 2026.ABSTRACT Muon tomography is a geophysical imaging technique with growing application across a range of geological and industrial settings. By observing the arrival of naturally occurring muons, it is possible to reconstruct subsurface density distributions in three dimensions.

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2303-2335, September 2026.Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2269-2283, September 2026.Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.
