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.

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.

Environmental evolution of cover deposits on chemically distinctive bare ground, New Zealand: review and temporal contexts

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1120-1152, December 2025.
ABSTRACT Chemically distinctive features such as high salinity, low nutrient contents, and extremes of pH can limit the development of a vegetation cover on soil‐free bare ground. This study synthesises our previous work on the geoecology of numerous chemically distinctive bare sites in the South Island and adds a temporal component within the last ...

Orogenic gold and geologic time: a global synthesis

Ore Geology Reviews, 2001
AbstractOrogenic gold deposits have formed over more than 3 billion years of Earth’s history, episodically during the MiddleArchean to younger Precambrian, and continuously throughout the Phanerozoic. This class of gold deposit is characteristi-cally associated with deformed and metamorphosed mid-crustal blocks, particularly in spatial association with
