Texture and geochemistry of multi-stage hydrothermal scheelite in the Dongyuan porphyry-type W-Mo deposit, South China: Implications for the ore-forming process and fluid metasomatism

American Mineralogist
Scheelite in the Dongyuan porphyry-type W-Mo deposit, South China, occurs both in porphyritic biotite granite and lamprophyre. Three types of scheelite (SchA, SchB and SchC) were identified in the porphyritic biotite granite, whereas two types (Schaand

The geological relationship between Kanmantoo Cu-Au deposit mineralisation, hydrothermal metasomatism and igneous intrusives

, 2018
This item is only available electronically. ; The Kanmantoo Cu-Au deposit has been in episodic operation since 1846, one decade after the capital city of Adelaide was established some 40 kilometres to the NW. Regionally and within the host stratigraphy there exists archetypal evidence of the Cambrian Delamerian Orogeny through a complex structural ...

Texture and geochemistry of multi-stage hydrothermal scheelite in the Tongshankou porphyry-skarn Cu-Mo(-W) deposit, eastern China: Implications for ore-forming process and fluid metasomatism

American Mineralogist, 2020
Scheelite from the Tongshankou porphyry- skarn Cu-Mo(-W) deposit occurs mainly as disseminated grains in the altered granodiorite porphyries at depth (Sch A), in the skarn coeval with retrograde alteration (Sch B) and in distal quartz veins crosscutting ...

Ore-bearing hydrothermal metasomatic processes in the Elbrus volcanic center, the northern Caucasus, Russia [PDF]

Geology of Ore Deposits, 2008
Precaldera, caldera, and postcaldera cycles are recognized in the geological evolution of the Pleistocene-Holocene Elbrus volcanic center (EVC). During the caldera cycle, the magmatic activity was not intense, whereas hydrothermal metasomatic alteration of rocks was vigorous and extensive. The Kyukyurtli and Irik ore-magmatic systems have been revealed

The Hydrothermal and Hydrothermal-Metasomatic Formation of Kaolin and A Genetic Classification of Clay Rocks [PDF]

Clay Minerals, 1959
A genetic classification of clay rocks is given in which five main types are recognized. In this classification minerals of the kaolin group formed directly from hydrothermal solutions, along with sulphides, sulphates, and pneumatogenic minerals, are separated from the same minerals formed by the hydrothermal-metasomatic action of gases and vapours on ...

Fingerprinting REE mineralization and hydrothermal remobilization history of the carbonatite-alkaline complexes, Central China: Constraints from in situ elemental and isotopic analyses of phosphate minerals

American Mineralogist, 2021
Carbonatites and related alkaline rocks host most REE resources. Phosphate minerals, e.g., apatite and monazite, commonly occur as the main REE-host in carbonatites and have been used for tracing magmatic and mineralization processes.
