Fluid inclusion study of the Boccassuolo VMS-related stockwork deposit (Northern-Apennine ophiolites, Italy) [PDF]

, 2015
Several Cyprus-type volcanogenic massive sulphide (VMS) deposits are found in the Jurassic ophiolitic series of the Northern Apennines. Stratabound, stratiform and stockwork deposits were formed in the western limb of the Neotethys (Ligurian Ocean) and ...

DiadFit: An open-source Python3 tool for peak fitting of Raman data from silicate melts and CO2 fluids

Volcanica
We present DiadFit—an open-source Python3 tool for efficient processing of Raman spectroscopy data collected from fluid inclusions, melt inclusions and silicate melts. DiadFit is optimized to fit the characteristic peaks from CO2 fluids (Fermi diads, hot

Fluid Inclusion and Oxygen Isotope Constraints on the Origin and Hydrothermal Evolution of the Haisugou Porphyry Mo Deposit in the Northern Xilamulun District, NE China

Geofluids, 2017
The Haisugou porphyry Mo deposit is located in the northern Xilamulun district, northeastern China. Based on alteration and mineralization styles and crosscutting relationships, the hydrothermal evolution in Haisugou can be divided into three stages: an ...

Hydrothermal Fluid evolution in the Dalli porphyry Cu-Au Deposit: Fluid Inclusion microthermometry studies

Journal of Economic Geology, 2015
Introduction A wide variety of world-class porphyry Cu deposits occur in the Urumieh-Dohktar magmatic arc (UDMA) of Iran.The arc is composed of calc-alkaline granitoid rocks, and the ore-hosting porphyry intrusions are dominantly granodiorite to quartz ...

The relation between Cu/Au ratio and formation depth of porphyry-style Cu-Au ± Mo deposits [PDF]

, 2018
Constraints on gold and copper ore grades in porphyry-style Cu-Au ± Mo deposits are re-examined, with particular emphasis on published fluid pressure and formation depth as indicated by fluid inclusion data and geological reconstruction.

Silicate-melt inclusions in recent Vesuvius lavas (A.D. 1631–1944): I. Petrography and microthermometry

European Journal of Mineralogy, 1992
Silicate-melt inclusions hosted by clinopyroxene, leucite, olivine, and plagioclase phenocrysts have been studied by petrography and microthermometry. Fourteen lavas erupted during the Mt. Vesuvius (southern Italy) recent activity (A.D. 1631-1944) have been examined.

Geology, alteration and mineralization style of the lithocaps in the north-northeastern Chah Musa deposit, part of the Toroud-Chah Shirin magmatic arc (south of Shahrood)

Journal of Economic Geology
The study area is situated in the northern part of the Central Iranian structural zone, northeast of the Toroud-Chah Shirin magmatic arc. In this area, late Eocene hypabyssal intrusions are emplaced within Eocene volcano-sedimentary sequences ...
