REGULARITIES IN THE VOLATILE ELENENTS DISTRIBUTION IN THE SURFICIAL ENVELOPE OF EARTH: PROBABLE HISTORICAL-MINERAGENICAL INTERPRETATION. Paper 4. Arsenic
Elevated concentrations of the volatile Hg, Sb, As, Tl, Bi tend to be located within the structural forms have been determined the tectonic blocking of the Earth crust. Areal distribution of the ore occurrences of the discrepant scales and ages let corroborate (sometimes disclose) position of the planetary rank ore-controlling structures as well as decipher its forming chronological successiveness, and estimate deepness. The present description of the historical-nineragenical analysis results goes on the series of papers being undertaken for the arsenic-ferrous objects. In difference from the Hg Mesozoic -Cenozoic accumulation the As occurrences are heterochronous much more, from Late Archean through Qurternary. Newly compiled database for model As minerals (ar- senopyrite and native arsenic) let disclose anomalous unevenness in the occurrences distribution on the Earth's continents.
