The detailed mineralogical and microgeochemical characteristics of polymetallic nodules collected from the Interoceanmetal Joint Organization (IOM, Szczecin, Poland) claim area, Eastern Clarion-Clipperton Fracture Zone (CCFZ, Pacific) were described in this study. obtained data applied for delimitation nodule growth generations estimation ratios (back-stripping using Co-chronometer method). met...
The goal of this paper is to improve our understanding of the costs and benefits of explicit deposit insurance. To this end, we compare the opportunity-cost value of deposit insurance services for a large sample of banks drawn from countries with or without explicit deposit insurance. After correcting for certain bankand country-specific factors, we find that the existence of explicit deposit i...
kajal kaolin deposit is located ~20 km northwest of hashtjin, ardebil province. field evidence and laboratory investigations show that the deposit is an alteration product of ignimbrites, tuffs, and trachy-andesites of eocene age. according to mineralogical data, the major rock-forming minerals include kaolinite, montmorillonite, polygorskite, orthoclase, zeolite (stilbite), quartz, and chalced...
This paper characterizes the optimal level of deposit insurance (DI) when bank runs are possible. In a wide variety of environments, the optimal level of DI only depends on three sufficient statistics: the sensitivity of the likelihood of bank failure with respect to the level of DI, the utility loss caused by bank failure (which is a function of the drop in depositors’ consumption) and the exp...
Abstract: the reduction agent. Pellets of barite ore containing about 95% BaSOtemperature, time, ore grain size and the type and grain size of the carbon materials. Graphite, coke and charcoal havebeen used as the reducing agent and the reduction experiments have been performed in the temperature range of 925-1150 °C. Apart from conducting the experiments using pellets made of ore powder, kinet...
