Magnetotelluric (MT) imaging results from mineral provinces in Australia and the United States show an apparent spatial relationship between crustal-scale electrical conductivity anomalies major magmatic-hydrothermal iron oxide-apatite/iron oxide-copper-gold (IOA-IOCG) deposits. Although these observations have driven substantial interest use of MT data to image ancient fluid pathways, exact ca...

Iron is the most important metal for modern industry and Sweden is by far the largest iron-producer in Europe, yet the genesis of Sweden's main iron-source, the 'Kiruna-type' apatite-iron-oxide ores, remains enigmatic. We show that magnetites from the largest central Swedish 'Kiruna-type' deposit at Grängesberg have δ(18)O values between -0.4 and +3.7‰, while the 1.90-1.88 Ga meta-volcanic host...

A thick succession of sedimentary rocks belonging to Tipam Group is well exposed all along the road cut sections near Buhchang village, Kolasib district, Mizoram. The heavy mineral suite of the Tipam sediments depicts a cosmopolitan nature. It comprises dominantly of non-opaque variety that includes zircon, tourmaline, rutile, staurolite, kyanite, sillimanite, apatite, epidote, garnet and hornb...

Microorganisms are ubiquitous in the shallow subsurface often attached to sediment surfaces where they alter the geochemical microenvironment and mediate weathering reactions. Microbial attachment on sediment grains, however, is heterogeneous and the variability of microbial occurrence cannot be easily explained. This study examined how phosphate mineral and iron oxide inclusions in feldspars i...

Understanding biomineralization processes provides a route to the formation of novel biomimetic materials with potential applications in fields from medicine to materials engineering. The teeth of chitons (marine molluscs) represent an excellent example of a composite biomineralized structure, comprising variable layers of iron oxide, iron oxyhydroxide and apatite. Previous studies of fully min...

Developing the innovative technology for efficient utilization of high-phosphate iron ore was inevitable choice resource strategy. In this paper, exploring a new method gasification removal phosphorus by sintering based on biomass. Combined with theoretical analysis and experimental research, effects different conditions (biochar type, addition proportion, basicity) reduction behavior were stud...

Mapping of carbonatites and related mineral deposits has occupied prominent place in resource exploration programs given their potential to host valuable concentrations critical metals such as rare earth elements niobium. Based on spectral characteristics most indicative minerals for these rocks, a mapping approach was developed using Advanced Spaceborne Thermal Emission Reflection Radiometer (...
