The objective of this research is to determine all processes in the magmatic evolution and related hydrothermal activities that created the volcanic rocks and associated ore-forming systems of the Bafq ‎mining district. Several iron oxide-apatite (IOA) deposits were investigated in this area with a focus on the Sechahun ore deposit. The Bafq ‎mining district is well known for hosting significan...

The Borujerd complex of western Iran is composed of intrusions and their surrounding contact aureole, with, pegmatites and quartz veins. Pegmatites differ in mineralogy, origin and age, and two groups can be distinguished. The Older Pegmatites (about 120 Ma age) intruded contact metamorphic rocks from the early magmatic stage, while the Younger pegmatites (52-70 Ma age) formed during the late m...

The Maliping large-scale Pb-Zn deposit is located in the Sichuan-Yunnan-Guizhou polymetallic metallogenic triangle area (SYGT), where ore body hosted interlayer fracture zone at interface between siliceous cataclastic dolomite and clastic rocks Lower Cambrian Yuhuchun Formation tectonically driven. Unlike other de-posits Sinian Carboniferous carbonate area, mechanism deep peripheral prospecting...

Abstract The role of deep hydrothermal fluid circulation through fractures and their impact on the sandstone host rock is studied in an extensional sedimentary basin (Cameros Basin, Spain) affected by a post-extensional metamorphism. quartzarenites Urbión Group constituted hydrocarbon carrier very low to low-grade metamorphism during Late Albian Coniacian. This process generated abundant quartz...

Fluid inclusion water isotope measurements in speleothems have great potential for paleoclimate studies as they enable the reconstruction of precipitation dynamics and land temperatures. Several previous observations, however, suggest that waters do not always reflect isotopic composition surface precipitation. In such cases, dripwaters are thought to be modified by evaporation cave environment...

Evidence of hydrothermal activity is reported for the Mesozoic pre- and syn-rift successions western Adriatic palaeomargin Alpine Tethys, preserved in Western Southalpine Domain (NW Italy). The products processes are represented by vein breccia cements, as well dolomitization silicification host rocks. In eastern part study area, interpreted necking zone continental margin, Middle Triassic dolo...

Abstract Post‐orogenic back‐arc magmatism is accompanied by hydrothermal ore deposits and mineralizations derived from mantle crustal sources. We investigate Zannone Island (ZI), Tyrrhenian basin, Italy, to define the source(s) of mineralizing fluids their relationships with regional petrological‐tectonic setting. On ZI, early Miocene thrusting was overprinted late post‐orogenic extension relat...
