Alkali Metasomatism and Th-REE Mineralization in the Choghart deposit, Bafq district, Central Iran
Geologia Croatica, 2017 The Choghart iron oxide-apatite (IOA) deposit is located 124 km southeast of Yazd, in the Bafq district within the Central Iranian microcontinent. The Choghart deposit is hosted by the rhyolitic rocks of the Early Cambrian volcano-sedimentary sequence ...

In situ study of the synthesis of thorite (ThSiO4) under environmental representative conditions
, 2020 Thorite, ThSiO4 with Zircon structure type, is one of the most abundant natural source of thorium on earth. While actinides are known to form nanoparticles in silicate medium, no direct link between those colloids and crystalline form of thorite was ...

A transient liquid-like phase in the displacement cascades of zircon, hafnon and thorite [PDF]
, 1998 The study of radiation effects in solids is important for the development of 'radiation-resistant' materials for fission-reactor applications'. The effects of heavy-ion irradiation in the isostructural orthosilicates zircon (ZrSiO4), hafnon (HfSiO4) and ...

Mineralogical Evidence for Highly Evolved Th‐Saturated Magma on Mars
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Thorium‐rich (Th‐rich) geological units have been detected by remote sensing in the Martian crust. However, there is still a lack of mineralogical evidence to constrain the magmatic processes responsible for these anomalies. In this study, we report the first discovery of thorite (ThSiO4) grains within a zircon fragment from Martian regolith ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Granitoid magmatism along the western Pacific margin records interactions between subduction dynamics and crust–mantle processes; however, the links between plate reorganization and magma‐source evolution remain debated. Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene ...
