Alteration Alteration, Mineralization and Geochemistry of Metamorphic Rocks Hosted Hydrothermal Gold Deposit at Rumbia Mountains, Bombana Regency, Southeast Sulawesi, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019
In Indonesia, gold is commonly mined from porphyry, epithermal and skarn type deposits that are commonly found in volcanic/magmatic belts. However, were recently numerous gold prospects discovered in association with metamorphic rocks.

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

New orogenic type gold occurrences in the Uyanga ore knot (Central Mongolia) [PDF]

E3S Web of Conferences, 2019
The Khangay-Khentey belt is located in central Mongolia (Central Asian Orogenic Belt). The Uyanga ore knot district of the Khangay metallogenic zone are hosted by the lower-middle Devonian volcanogenic-sedimentary Erdenetsogt formation. The new Burgetei,

Attention and Geological Knowledge Guided Spectral‐Spatial Networks for Geochemical Anomalies Recognition

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Achieving both accuracy and interpretability in deep learning models for geochemical anomaly recognition constitutes a significant challenge. To overcome this challenge, this study developed a novel interpretable dual‐branch network combining a spectral attention bidirectional RNN (BiRNN) branch and a spatial attention CNN branch guided with ...

Geological characteristics of the Daduhe gold belt, western Sichuan, China: Implications for exploration

Open Geosciences
Geological characteristics, genetic model, and exploration implications in the Daduhe gold belt are studied. Three categories of gold deposits have been distinguished: “gold deposits in the basement (GDB),” “gold deposits in the cover layer (GDC),” and ...

Emplacement of Hybrid Continental‐Oceanic Arc Terranes Without Collision: The Devonian Calliope Arc (New England Orogen, Australia)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The accretion of allochthonous provinces, derived from oceanic plates, has traditionally been considered an important contributor to continental growth. However, increasing evidence shows that some oceanic terranes (e.g., island arcs) are not “exotic,” as suggested by the presence of continental‐derived sedimentary provenance.

Geology of the Yeşilyurt gold deposit: an example of low-angle normal fault related mineralization, Eastern Anatolia-Turkey

Bulletin of the Mineral Research and Exploration, 2021
Yeşilyurt gold mineralization is located within the provincial borders of Malatya and Adıyaman in the East Anatolian Region. This mineralization is one of the gold deposits which correlated with low-angle normal/detachment fault.

The Role of Mafic Intrusion in Seismotectonics: Insights From the 1668 M 8.5 Tancheng Earthquake Rupture Zone Along the Tan‐Lu Fault Zone, Eastern China

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tan‐Lu Fault Zone (TLFZ), the largest lithosphere‐scale strike‐slip fault in eastern China, has experienced multiple tectonic stages and remains high seismic activity, including the 1668 Tancheng earthquake (M 8.5). Here we employ dense‐array receiver functions to resolve crustal thickness, Vp/Vs ratio, and seismic discontinuities in the ...
