Regional geochemical and geophysical surveys in the Berwyn Dome and adjacent areas, north Wales [PDF]

, 1984
This report describes stream sediment and gravity surveys carried out across the Berwyn Dome and adjacent areas. The gravity survey confirmed the presence of a broad regional Bouguer anomaly low in the central part of the Dome, on which is ...

Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]

, 2019
The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...

Mineralization Characteristics of the Li‐rich Muscovite Granite in the Mufushan Batholith, Central China: Insights into the Rare Metal Mineralization Models of Batholithic Complex

Acta Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.
Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Chemical Discrimination of Rutile From Different Metamorphic Source Rocks: Dealing With Hierarchical Data Structures in Random Forest Classification

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 112-137, February 2026.
ABSTRACT Rutile provides a wealth of petrochronological information in metamorphic geology and due to its high stability during processes of the sedimentary cycle, rutile takes a special position in sedimentary provenance analysis. Besides being one of the classical minerals datable using the U–Pb system, rutile incorporates a broad range of trace ...

Plasma dissociation of monazite

IOP Conference Series: Materials Science and Engineering, 2019
Abstract Monazite is a phosphate mineral which contains a significant amount of rare earth elements (REE) with thorium (Th) and a low concentration of uranium (U). The radioactive components of monazite, Th and U, make it an unattractive source of REE due to the added cost associated with radioactive waste handling.
