·Veins of gold such as this one trapped in quartz and granite may deposit when the high pressure water in which they were dissolved suddenly vaporises during an earthquake Credit Shutterstock
We present petrographic and microthermometric evidence for precipitation of Au Ag Te rich melt directly from hydrothermal fluids and subsequent entrapment as primary melt inclusions within pyrite from quartz veins of the Xiaoqinling lode gold district southern margin of
·Quartz veins are common geological features found in a variety of rock types and play an important role in understanding the processes that shape the Earth s Gold bearing quartz veins for example are frequently found in areas associated with hydrothermal activity and can be important targets for gold exploration and mining Recent

·Large quantities of iron oxides such as magnetite ironstone or hematite in an area can also indicate the presence of gold Rock 1 Quartz Veins Quartz veins are closely associated with the presence of gold and are visible in rock faces and cliffs in the surrounding area Weathered chunks of quartz lying on the ground and smaller quartz
· a Gold Quartz sulfide vein showing grain of pyrite enclosing chalcopyrite and gold in association with quartz; b Inset photomicrograph showing primary carbonic CO 2 ± CH 4 aqueous carbonic H 2 O CO 2 NaCl ± CH 4 and aqueous biphase H 2 O NaCl inclusions hosted within quartz; c Inset photomicrograph showing presence
Quartz vein type gold deposits of Southeastern Guizhou Province in the southwestern margin of Jiangnan Orogen which are typical orogenic gold deposits are hosted in Neoproterozoic Banxi Group sub greenschist facies metamorphic rocks However similar to other gold deposits in Jiangnan Orogen mineralization ages of these deposits is a controversial issue and its
Adagio Gold quartz from Viatera features subtle gold veins articulating their bright notes without missing a beat The white base color soft and brilliant at the same time has more in its repertoire than meets the eye Like a tender melody this design whispers promises of
·A simplified scheme to categorise quartz vein morphology from gold deposits is based on the growth direction of quartz or pseudomorphed chalcedony in the veins The categories are scale independent and are 1 face control 2 displacement control 3 parallel control 4 radiating 5 non directional control 6 replacement and 7
·Figure 1 Examples of Giant Quartz Veins cropping out in different tectonic settings A the Esquerdes de Rojà vein in the Canigó Massif pre Variscan basement of the Pyrenees SW Europe; B the Poolamacca veins in the Broken Hill Inlier western New South Wales Australia from Citation Bons 2001 ; C the China Wall vein in the Halls Creek Belt
·Fluid inclusions were trapped during all stages of the development of the quartz vein system The pre gold veins exhibit evidence in the form of pervasive development and alignment of quartz and calcite sub grains and fracturing of epidote for intense brittle ductile deformation related to the progressive D 2 deformation event Hence
·Complex internal textures are recorded in quartz veins in the Muping Rushan gold belt as the deposition of quartz veins is clearly controlled by fault movements Such movements cause ore fluid migration and enhancement of permeability along the fault as a consequence of fluid pressure and shear stress fluctuation Sibson et al
·The genesis of late metamorphic gold lodes in the northwestern Alps has remained enigmatic In order to trace the source of the ore bearing fluid at the Brusson locality and to test current genetic models 130 Rb Sr isotope measurements have been performed on hydrothermal vein minerals their fluid inclusions and their unaltered country rocks
·Based on these datasets we present a new model for the genesis of gold bearing quartz veins in the Nazca Ocoña metallogenic belt The study suggests that most of the vein related gold formed in association with a shallower hydrothermal event potentially in association with the emplacement of batholiths and shallower intrusions in the Late
·Gold sulfide quartz veins exhibit textural features indicative of repeated mylonitization recrystallization and muscovite crystallization New 40Ar/39Ar ages of muscovite flakes from the auriferous quartz veins and from the altered wallrock overlap within analytical uncertainty at 583 Ma which corresponds to the climax of extension related
·The gold bearing quartz veins contain as much as 3% sulfide minerals Pyrite is the main sulfide mineral and is associated with minor chalcopyrite Sulfides are commonly altered to hematite
·Based on these datasets we present a new model for the genesis of gold bearing quartz veins in the Nazca Ocoña metallogenic belt The study suggests that most of the vein related gold formed in association with a shallower hydrothermal event potentially in association with the emplacement of batholiths and shallower intrusions in the Late
