In this paper we study in detail the post-growth annealing of a copper-containing material deposited with focused electron beam induced deposition (FEBID). The organometallic precursor Cu(II)(hfac)2 was used for deposition and the results were compared to that of compared to earlier experiments with (hfac)Cu(I)(VTMS) and (hfac)Cu(I)(DMB). Transmission electron microscopy revealed the deposition...
Sputtering was utilized to deposit polycrystalline Cu and CrN films sequentially onto Si(100) substrates, forming specimen assemblies in which predominantly ⟨111⟩ oriented Cu thin films of varying thicknesses were confined between Si and CrN. Cylindrical micro-pillars of CrN/Cu/Si(100)were fabricated through focused ion beammilling,with the interfaces either normal to the axial direction or at ...
In this paper are presented general geological data for the polymetallic Hajvalia deposit. particular, we have scientific results regarding chemical and mineralogical composition of sulfur mineralizations from The distribution main metals used during mining activity in deposit has been studied with special emphasis. From microscopic description mineral samples deposit, following compositions re...
در این پایان نامه، به بررسی خواص بلندرهای دوگانه و هم بافته می پردازیم. یک $cu$-بلندر، به طور خلاصه یک مجموعه ی هذلولوی ناوردا با تجزیه ای به شکل $e^{ss} oplus e^u oplus e^{uu}$ به طوری که در آن $dim e^u = 1$ و تصویر مناسبی از یک مجموعه ی پایدار آن دارای بعد توپولوژیکی بزرگتر از بعد خود مجموعه ی پایدارش می باشد. می توان یک $cs$-بلندر را به طور مشابه تعریف نمود. %اساسا ساختارشان از ...
The Tullacondra Cu-Ag deposit is located on the southern margin of Lower Carboniferous Irish Midlands orefield and contains historical reserves approximately 4.2 Mt at 0.7% Cu 27.5 ppm Ag. hosted within hanging wall a feeder fault, EW-trending Fault, where sulfides sulfosalts containing elevated Cu, Ag, As, Sb deposited, whereas Zn Pb are nearly absent. deposition in took place along bedding be...
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...
supergene oxidation-leaching and secondary sulfide enrichment in the sarcheshmeh porphyry cu-mo deposit generated a supergene profile to depths of 20 to 80 meters with oxide ore reserve about 22 mt. @1.08% cu and sulfides ore [email protected]% cu. geochemical distribution and behavior of trace metals associated with cu namely mo, au, and ag in the supergene profile of the sarcheshmeh were po...
Modeling based on equilibrium thermodynamic and physicochemical condition suggests that Bi-rich melts can efficiently scavenge Au from hydrothermal fluids, even if these fluids are highly undersaturated with respect to Au minerals. At this study the Kuh-e Dom prospecting area in northeastern of Ardestan city (northern part of Anarak metallogenic province) as the prominent sample of Iron Oxide C...
The massive sulphide deposit at Kantienpan Cu-Zn mine is hosted by volcano sedimentary succession known as the Areachap Group, in the eastern part of Namaqua Metamorphic Province, South Africa. The deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted m...
