Mineral systems: Their advantages in terms of developing holistic genetic models and for target generation in global mineral exploration

Geosystems and Geoenvironment, 2022
Since the concept of mineral systems was first proposed, there have been growing calls for their use in deriving holistic genetic models and in assisting in exploration targeting in a world of diminishing mineral discoveries.

Antimony in rutile as a pathfinder for orogenic gold deposits

Ore Geology Reviews, 2019
Abstract In our study we explore the applicability of rutile as a pathfinder for orogenic gold deposits, which are an important source of this metal worldwide. We analysed rutile associated with orogenic Au deposits from three different Precambrian terranes, the Capricorn Orogen, the Barberton Greenstone Belt and the Ashanti Belt, all of which formed

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 ...
