[HTML][HTML] Petrogenesis of granitic pegmatite veins: Perspectives from major element and B isotope in tourmalines, Chakabeishan, Northern Tibetan Plateau
The petrogenesis of regionally zoned granitic pegmatite veins remains debated. Because of
the economic significance, we carried out a study on the Chakabeishan (CKBS) pegmatite …

[HTML][HTML] Failed genesis of a Fe-skarn deposit caused by redox states of intrusion and wall rocks (Torre di Rio, Island of Elba, Italy)
Abstract The Torre di Rio skarn (Island of Elba, Italy) is a pyroxene-ilvaite-epidote skarn that
hosts a Fe-oxide mineralization and is the type locality of the mineral ilvaite. In contrast with …

Fractures, fluid flow and inherited structures in geothermal systems: inputs from the Fe-ore deposits of eastern Elba Island (Northern Apennines, Italy)
Geothermal systems in terrains affected by polyphase deformation have reservoirs with a 3D
geometry that is always difficult to predict. In this paper we describe a fossil exhumed …
