In this work, antiwear nanoimprint templates were made by depositing and patterning diamondlike carbon DLC films on Si and quartz. A capacitively coupled plasma enhanced chemical vapor deposition PECVD system was configured to deposit 100 nm–1 m thick DLC films on Si and quartz substrates. These films were characterized with Raman spectroscopy, electron energy loss spectroscopy, atomic force mi...

kajal kaolin deposit is located ~20 km northwest of hashtjin, ardebil province. field evidence and laboratory investigations show that the deposit is an alteration product of ignimbrites, tuffs, and trachy-andesites of eocene age. according to mineralogical data, the major rock-forming minerals include kaolinite, montmorillonite, polygorskite, orthoclase, zeolite (stilbite), quartz, and chalced...

the zonouz kaolin deposit is located ~15 km northeast of marand, east-azarbaidjan province. based on physical features in field investigations, such as color, five distinct kaolin types including (1) white, (2) lemon, (3) gray, (4) brown, and (5) yellow are distinguished in the deposit. field evidence and petrographic studies indicate that the deposit is genetically close to trachy-andesite roc...

The Gandy gold-base metal deposit is located in Tertiary Torud-Chahshirin volcano-plutonic range, north of Central Iran. Various styles of gold mineralization occur throughout the range. Mineralization at Gandy occurs in close spatial relation with rhyolitic domes in a caldera setting in a series of narrow brecciated veins. Two mineralogically and spatially different argillic alterations have a...

A novel design for a rotating electrochemical quartz-crystal microbalance (rEQCM) which includes easily and reproducibly exchangeable quartz-crystal holders is described. The rEQCM allows for well-controlled mass-transport conditions at the working electrode on a 10 MHz quartz crystal. Together with the flexibility of the proposed design, this makes it useful for a wide range of applications in...

The Xinjiazui gold deposit, a newly discovered is situated in the northwestern margin of Yangtze Block, China. source and genesis mineralization are poorly understood. It urgent to use H–O isotopic composition quartz geochemistry pyrite evaluate origins Au ore-forming fluids this deposit. Three types were identified, including synsedimentary framboidal pyrites (Py0), directional arrangement pre...

Introduction: The Saibagou gold deposit, located in the eastern part of tectonic belt northern Qaidam Basin western China, has its ore bodies strictly controlled by regional fault system. Despite this understanding, there remain controversies surrounding deposit’s metallogenic epochs, sources ore-forming materials, and properties fluids. To address these controversy, process deposit can be furt...
