Prospectivity analysis of orogenic gold deposits in Saqez-Sardasht Goldfield, Zagros Orogen, Iran [PDF]

Ore Geology Reviews, 2017
Abstract Diverse deposit-types or mineral systems form by diverse geological processes, so translation of knowledge about the controls of mineralization acquired from the 4D geological modeling into 2D spatial predictor maps is a major challenge for prospectivity analysis.

Laurasian Seaway History During the Early Jurassic From Quantitative Mineralogy and Detrital Zircon Dating

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Laurasian Seaway comprises a N‐S oriented trans‐Pangaean corridor linking Tethys to the Boreal Sea during the Jurassic, and direction of water flow has been the subject of considerable debate. The Llanbedr (Mochras Farm) borehole, Cardigan Bay Basin, Wales, is a uniquely informative record that comprises an expanded deep‐marine silty ...

Fluid Inclusion and H–O–S–Pb Isotope Geochemistry of the Yuka Orogenic Gold Deposit, Northern Qaidam, China

Geofluids, 2019
The Yuka gold deposit, located in the western part of northern Qaidam, contains Au orebodies hosted in early Paleozoic metamorphic basic volcaniclastic rocks. The Yuka mineralization can be divided into three stages: early quartz-pyrite (stage-I), middle

Long‐Term Deformation in the Alpine‐Provence Foreland Constrained by In Situ Calcite U‐Pb Dating

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The evolution of the Alpine‐Provence foreland is characterized by multiple deformation phases since the Mesozoic, representing successive compressional and extensional episodes. The precise timing and spatial evolution of these deformation phases remain poorly constrained due to the lack of absolute geochronological data. Here, we present U–Pb

Fluid inclusion and H–O–S isotope constraints on the genesis of the Ashawayi gold deposit, Southern Tianshan, Xinjiang, NW China

Frontiers in Earth Science
The Ashawayi gold deposit is situated in the eastern part of the Southern Tianshan Sb–Hg–Au metallogenic belt, a significant source of gold in China. This deposit exhibits typical disseminated mineralization controlled by faults or fractures.

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

Geophysical 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 ...
