Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Studies of liver phosphorylase in hepatic injuries. I. Alteration in enzyme activity [PDF]

, 1978
Phosphorylase activities (total and a form) were determined in the livers of experimental hepatic injuries with carbon tetrachloride or galactosamine and the livers of patients with liver diseases.

Quantifying element mass transfer in the Jiling Na-metasomatic hydrothermal uranium deposit, Northwest China

The Na-metasomatic hydrothermal uranium deposits are relatively widespread, low in grade (less than 1 % U3O8) but high in tonnage. Although it has been considered that this type of deposit was formed due to hydrothermal alteration unrelated to magmatic ...

Petrologic and geochemic features of the ore-containing substratum in hydrothermal gold deposits. P. 1. Petrologic and geochemical concept of near-ore metasomatism

Известия Томского политехнического университета: Инжиниринг георесурсов, 2017
The relevance of the research is caused by the necessity to correct and elaborate on geological (metallogenical) component of the hydrothermal gold deposits formation theory within the framework of which the conflicting ideas about ore-formation ...

Age and Origin of the Mesoproterozoic Iron Oxide-Apatite Mineralization, Cheever Mine, Eastern Adirondacks, NY

Geosciences, 2018
At the Cheever Mine, located in the eastern Adirondack Mountains of the Mesoproterozoic Grenville Province, iron oxide-apatite ore forms a narrow (<3 m) sheet cross-cutting metasomatically altered, magnetite-bearing, albite-rich leucogranitic host ...

Monazite-(Ce) formation as a product of hydrothermal chevkinite-(Ce) alteration: Experimental constraints

Mineralogia
Chevkinite-group minerals are rare earth element (REE) carriers in alkaline magmatic and metasomatic systems, yet their hydrothermal stability and alteration pathways remain poorly constrained.

Magmatic significance and hydrothermal alteration of layered chromitites from the Bracco Gabbro Complex, Ligurian Ophiolites, Italy

Bulletin of the Mineral Research and Exploration
The Bracco chromitites are hosted in the Mesozoic Ligurian Ophiolites (Italy) and provide key insights into the magmatic and post-magmatic (i.e. metamorphic and hydrothermal) evolution ofgabbro-hosted chromitites in an oceanic mantle.

8. METASOMATIC AND METAMORPHIC PECULIARITIES OF THE DIABASE DIKE ALTERATION IN HOLE 504B, LEG 140

, 1996
The diabase dikes recovered during Leg 140 display four types of mineralogical alteration: (1) chlorite + amphibole + titanite; (2) chlorite + amphibole + ilmenite; (3) epidote + prehnite + anhydrite; (4) zeolites + smectite.

Metasomatic oxidation of subduction zone mantle: Implication for arc metallogeny

, 2018
This thesis investigates redox processes taking place during metasomatic alteration of the Earth’s mantle by slab fluids, and the subsequent partial melting of metasomatised mantle, by applying different geochemical and petrological techniques to ...

Crystallisation and breakdown of metasomatic phases in graphite-bearing peridotite xenoliths from Marsabit (Kenya) [PDF]

, 2007
Mantle-derived xenoliths from the Marsabit shield volcano (eastern flank of the Kenya rift) include porphyroclastic spinel peridotites characterized by variable styles of metasomatism.
