Apatite Fission Track Thermochronology of Granite from Duobaoshan Porphyry Cu (Mo) Deposit, Northeast China: Implications for Cooling History and Ore Preservation

open access: yesGeofluids, 2022
The Duobaoshan Cu (Mo) deposit is one of the oldest super large porphyry deposits in the eastern part of the Central Asian orogenic belt. Although ore-forming processes have been extensively concerned, the post-mineralization ore preservation state was ...

The Occurrence and Morphology of Naturally Occurring Respirable Mordenite Mineral Fibres in New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Mordenite is a naturally occurring zeolite mineral that is the seventh most common zeolite mineral globally, forming at low temperatures (≥100°C) in hydrothermal systems. In New Zealand, extensive deposits of mordenite are commonly associated with areas of hydrothermal alteration, particularly in the Coromandel and Taupo Volcanic Zones.

Middle Cretaceous Andean‐Type Arc Evolution in the Sanandaj–Sirjan Zone (Shalair Valley), Iraq: New Geochronological and Geochemical Constraints

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±

Finite Element Modelling of Synthetic Normal Resistivity Logging Tool: Insights Into Vein Parameters, Borehole Fluids and Electrode Configuration

open access: yesGeophysical Prospecting, Volume 74, Issue 5, June 2026.
ABSTRACT Borehole resistivity logging can play an important role in subsurface exploration by enhancing the accuracy of surface data inversion models. However, its application in the mining industry remains limited due to challenges posed by complex geological formations, particularly in vein‐hosted deposits such as orogenic gold and porphyry copper ...

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

open access: yesActa Geologica Sinica - English Edition, Volume 100, Issue 3, Page 795-813, June 2026.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo
