The sowthwest of Sorkh kuh prospecting area is located in 120 km SW of Birjand city, western Lut Block. Geology of this area comprising andesitic and basaltic volcanic rocks, which have intruded by intrusive rocks such as hornblende diorite, hornblende tonalite, and biotite monzonite caused extensively alteration and mineralization. Based on remote sensing, field survey, petrography, and XRD, m...

introduction the study area is located in the central part of the khaf- kashmar- bardaskan volcano-plotunic belt (briefly kkbb). several iocg deposits such as tanourjeh au-bearing magnetite deposit and kuh-e-zar specularite-rich au deposit have been explored in kkbb. geology, alteration, mineralization, geochemistry and fluid inclusion results in kashmar suggest the iocg type au-bearing magneti...

Abstract Filo del Sol is a composite porphyry-epithermal deposit, straddling the frontier between Argentina and Chile at latitude 28°29′ S, that has attracted great deal of recent attention because several drill intersections in excess 1 km long with unusually high Cu, Au, Ag grades. The deposit part 8.5-km-long, N- to NE-trending alignment porphyry high-sulfidation epithermal centers, which, t...

The Tonggou deposit is a porphyry Cu and vein-type Cu-Zn mineralization system located in the Bogda Orogenic Belt, north of Eastern Tianshan. Systematic fluid inclusion analyses were performed on granular quartz from magnetite–quartz stage pyrite–chalcopyrite–quartz mineralization. During early mineralization, ore-forming fluids at high temperatures (450–501 °C) salinity (51.2–55.2 wt.% NaCl eq...

Gold bearing veining linked to transcrustal fault zones in the Transantarctic Mountains (northern Victoria Land, Antarctica)" (2007). Related Publications from ANDRILL Affiliates. Paper 20. Summary Gold mineralization is associated with the paleo-Pacific margin of Gondwana and is related to processes of subduction/accretion and magmatism. Northern Victoria Land (Antarctica) was part of this mar...

UNLABELLED The structure of vertically aligned carbon nanotubes (CNTs) severely depends on the properties of pre-prepared catalyst films. Aiming for the preparation of precisely controlled catalyst film, atomic layer deposition (ALD) was employed to deposit uniform Fe(2)O(3) film for the growth of CNT arrays on planar substrate surfaces as well as the curved ones. Iron acetylacetonate and ozone...

The Bodaibo gold-bearing district in the Lena gold province of Siberia is one largest and oldest placer provinces world. Approximately 1650 tons has been extracted from region. Precise studies on source these unique deposits are lacking still controversial. Native four different locations was gathered to investigate its morphology, chemical signatures, structure inclusions. Some data primary be...

We experimentally demonstrate the integration of silicon-vacancy centers in nanodiamonds (SiV-NDs) with an optical nanofiber (ONF). grow SiV-NDs on seed NDs dispersed a quartz substrate using microwave plasma-assisted chemical vapor deposition method. First, we search and characterize inverted confocal microscope atomic force (AFM). Subsequently, pick up from deposit them surface free-standing ...
