The Shalang vein-type polymetallic ore deposit is located about 10 km southwest of Kerman and 70 km northeast of Sirjan, and lies in the central part of the Dehaj-Sarduieh metallogenic belt. This deposit is hosted by dacitic and andesitic vitric and crystal tuffs along with andesitic-dacitic lava flows of Eocene age. The alteration zones related to this deposit are propylitic, intermediate argi...
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 Zamin Hossein copper deposit, as a part of the Dehaj- Sarduiyeh metallogenic belt, is located about 170 km southeast of Kerman city. This deposit is accompanied by Eocene volcanic (andesite, andesi-basalt and pyroclastic) and Eocene intrusive body (granodiorite and granite). The propylitic, sericitic, argillic-sericitic and silicic alterations are associated with this deposit. Chalcopyrite ...
Qaleh-Zari specularite-rich Cu-Ag-Au deposit is located 180 Km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline of 40.5±2 Ma and Jurassic sandstones and shales. Three major sub-parallel steep quartz veins are identified in different rock types, in particular andesitic rocks. The Qaleh-Zari deposit is a specularite-rich hydrothermal, Cu-Ag-A...
Mineralogy and fluid inclusion investigations in the Zarshuran gold deposit, north of Takab, NW Iran
The Zarshuran Carlin-type gold deposit is located about 30 km north of Takab, West-Azarbaidjan Province, NW Iran. Interaction between the ore-forming fluids and the host carbonates and shales resulted in development of the decarbonatization, argillic, alunite, silicic, and sulfide alteration zones in the study area. Based on mesoscopic and microscopic studies on drill core samples, gold mineral...
Abstract Hydroformed parts are widely used in industrial automotive because of their higher stiffness and fatigue strength reduced weight relative to corresponding cast welded parts. This paper reports a hydraulic-forming experimental platform for rectangular tube fittings that was constructed conduct an experiment on the hydraulic forming fittings. A finite element model established basis flui...
We identify a dominant mechanism in the interaction between a slender flexible structure undergoing free vibrations in sheared cross-flow and the vortices forming in its wake: energy is transferred from the fluid to the body under a resonance condition, defined as wake-body frequency synchronization close to a natural frequency of the structure; this condition occurs within a well-defined regio...
