In this study two small, but genetically related iron carbonate deposits Mačje Jame and Vranjski Potok, south west of Busovača (MBSM), located in the pre-Devonian metamorphic complex were investigated in detail. Analyses of the main chemical components, trace elements, REE, isotope composition of C, O, S, 87Sr/86Sr ratio of rhyolite, plot of REE normalized to CI chondrites and a microscopic stu...

In this paper, the development of a fully implantable wireless sensor able to provide continuous real-time accurate pressure measurements is presented. Surface Acoustic Wave (SAW) technology was used to deposit resonators on crystalline quartz wafers; the wafers were then assembled to produce a pressure sensitive device. Excitation and reading via a miniature antenna attached to the pressure se...

introduction arefi quartz-bearing conglomerate (middle jurassic) is situated within binalud structural zone. the unit is trending nw-se located 25 km south of mashhad. more than 97% of the pebbles are quartz as mono-crystalline, poly-crystalline, and minor fragments of chert, quartzite, and mica schist. less that 3% of the remaining minerals are feldspar, mica, chlorite, hornblende, tourmaline,...

Quartz is one of the most abundant minerals. Used in a variety materials, it preserves geological history and reflects alteration conditions. Data were collected (>2400 data points) from more than 40 ore deposits to understand its internal texture geochemistry. Cathodoluminescence imaging technique for examining quartz that may reveal information about crystal’s origin evolution. The dominan...

Located on the west coast of Pacific Ocean, Jiaodong gold concentration area is one world's famous deposit areas. Its unique metallogenic environment and background are favored by geologists all countries, multi-level multi-disciplinary scientific research work has been carried out in this area, good results have achieved. Linglong deposit, located 20 km northeast Zhaoyuan, Shandong, a quartz v...

The Jiadi gold deposit, situated in the Southwestern region of Guizhou, is a large-scale, recently discovered, basalt-hosted, and fine-grained disseminated deposit. This study has unveiled that tectonic deformation deposit can be categorized into four stages: Late Paleozoic crustal uplift brittle (D1-deformation) stage; Early Yanshanian NW-trending compressive ductile (D2-deformation) NS-trendi...
