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.

Mineral Prospectivity Prediction in the Mayoumu Area, Tibet, Based on Multi-Source Exploration Information and Ensemble Learning Models

Remote Sensing
Plateau–orogenic belts host a substantial share of global gold resources, yet quantitative prospectivity mapping is challenged by complex mineralization and strongly heterogeneous, multi-scale datasets.

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.
