GEOELECTRICAL CHARACTERISTICS OF GOLD ORE DEPOSITS OF THE UPPER PRIAMURYE REGION

Tikhookeanskaya Geologiya, 2019
The results of measurements of the electrical properties of rocks and induced polarization surveying are analyzed for three gold-ore deposits including the Bamskoe, Berezitovoe, and Pokrovka in the Upper Priamurye region. The spatial correlation is shown between mineralization zones and contrasting resistivity boundaries mapped within the gold-ore ...

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

Impacts of reclamation approaches on plant establishment in an arid environment during copper mine revegetation

Restoration Ecology, EarlyView.
Abstract Introduction Revegetation using native vegetation is a commonly used technique to reclaim landscapes degraded by mining activities. Revegetation efforts in the arid Southwestern United States face physical, geochemical, hydrological, and biological challenges unique to drylands.

EXPECTED OCCURRENCE OF THE BLIND ORE BODIES AT THE LOWER LEVELS OF THE BALEI DEPOSIT AND A MECHANISM OF THE RICH ORES FORMATION AT THE NEAR-SURFACE GOLD-SILVER ORE DEPOSITS

Известия высших учебных заведений: Геология и разведка, 2017
The gold ore chimneys of 2 types have been shown to be developed at the near-surface deposits of gold and silver ores. These types are: 1 - bulk ones, of the vein-nested-veinlet ore bodies of stockwork shapes and 2 - small pay streaks of the ore bodies ...

VEGF inhibitor‐induced vascular dysfunction involves redox‐sensitive PARP activation and SIRT1 disruption

Experimental Physiology, EarlyView.
Abstract Vascular endothelial growth factor receptor (VEGFR) inhibitors are effective antiangiogenic agents used in cancer therapy. However, they are associated with cardiovascular disease, including hypertension and vascular dysfunction. The molecular mechanisms underlying these cardiovascular toxicities are unclear, but oxidative stress might be ...

Phased combined development of gold ore deposits

Sustainable Development of Mountain Territories
Introduction. It is noted that in the Russian gold mining industry, the profitability of gold production is associated with the development of technologies for leaching it from substandard ores and enrichment waste. It is shown that the priority aspect of the development of substandard raw materials is to increase the yield of more gold with acceptable
