Cement stratigraphy: image probes of cathodoluminescent facies [PDF]

open access: yes, 2018
Cement stratigraphy of carbonates aims to establish the chronology of processes involved in the rock diagenesis. Regional cement stratigraphy allows correlations and understanding of the petrological heterogeneities in reservoirs and aquifers, but is a ...

The Roses giant quartz vein (Cap de Creus, Eastern Pyrenees): Geology and fluid inclusion data.

open access: yes, 2016
The Pyrenean Axial Zone is characterized by thick series of metasedimentary and orthogneissic materials derived from pre-Variscan rocks. These sequences were intruded by large bodies of Variscan granitoids, some exposed after the Alpine orogeny.

Modification of fluid inclusions in quartz by deviatoric stress. II: experimentally induced changes in inclusion volume and composition [PDF]

open access: yes, 2018
Fluid inclusions in quartz are known to modify their densities during shear deformation. Modifications of chemical composition are also suspected. However, such changes have not been experimentally demonstrated, their mechanisms remain unexplained, and ...

Application of fractal geometry for recognizing the pattern of textural zoning in epithermal deposits (case study: Sheikh-Darabad Cu-Au indices, East-Azarbaijan province)

open access: yesJournal of Economic Geology, 2013
Isotopic and microthermometry results from Sheikh-Darabad Cu-Au indices in Mianeh region, East-Azarbaijan province, indicate Cenozoic post-magmatic activities with developed adularia facies through an extended and Neogene related alteration that is given

Late Cretaceous structural control and Alpine overprint of the high-sulfidation Cu-Au epithermal Chelopech deposit, Srednogorie belt, Bulgaria [PDF]

open access: yes, 2018
The Chelopech epithermal high-sulfidation deposit is located in the Panagyurishte ore district in Bulgaria, which is defined by a NNW alignment of Upper Cretaceous porphyry-Cu and Cu-Au epithermal deposits, and forms part of the Eastern European Banat ...
