Ultrahigh‐Temperature Metamorphism and Near‐Isobaric Cooling of Garnet‐Orthopyroxene Granulite Xenoliths in the Sancheong Anorthosite, Yeongnam Massif, Korea

Journal of Metamorphic Geology, Volume 44, Issue 1, Page 20-46, January 2026.
ABSTRACT Elevated heat flow associated with mafic magmatism in accretionary orogens has often been proposed as a driving mechanism for (ultra)high‐temperature (UHT) metamorphism and anatexis. The Sancheong–Hadong complex, located in the southern Yeongnam Massif, Korea, consists of a ca.

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.

Characterization of ore-forming systems - advances and challenges [PDF]

, 2018
Economically viable concentrations of mineral resources are uncommon among the predominantly silicate-dominated rocks in Earth's crust. Most ore deposits that were mined in the past or are currently being extracted were found at or near Earth's surface ...

A Hybrid LightGBM–WOA Model for Accurate Prediction of Back‐Break in Mine Blasting Operations: A Case Study

Shock and Vibration, Volume 2026, Issue 1, 2026.
Back‐break (BB), a significant environmental concern in mining operations, arises from the improper execution of blasting techniques. The primary cause of BB is the inadequate design of blasting pattern parameters, which leads to structural issues such as fractures, overhangs, and underhangs on the construction face.

The tungsten-gold veins of Bonnac (French Massif central): new constraints for a Variscan granite-related genesis

BSGF - Earth Sciences Bulletin, 2021
In the Brioude-Massiac district (French Massif Central: FMC), a network of W-As-Bi-Au quartz veins constitutes the Bonnac deposit, where tungsten is the major economic element, together with high-grade gold (up to 15 g/t Au).

Microscale geochemical variations in metamorphic‐hydrothermal scheelite and insights into trace element sources (Otago Schist, New Zealand)

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 659-674, December 2025.
ABSTRACT Scheelite (CaWO4) trace elements are frequently used to fingerprint sources of mineralising fluids or styles of mineralisation. However, the chemistries of scheelite from hydrothermal‐metamorphic Otago Schist scheelite‐quartz veins have complicated parageneses.
