Volborth; suff. -ite ( Min. ).] Min.: A mineral occurring in small tabular crystals on a sandstone of the Permian formation in the Urals. Crystallization, hexagonal; hardne , 3-3-5; specific gravity, 3.55; luster, pearly; color, olive-green, citron-yellow; streak, yellowish green. Analyses made by Genth gave results which justified the following formula: (Cu,Ba,Ca)3V2O8+ 3CuH2O2+12aq., which requires, vanadic acid, 1963; protoxide of copper, 38.41; baryta, 6-17; lime, 6.77; water, 29·02=100. "Its situation is romantic, at the foot of a volcanic mountain."- Field , Feb. 4, 1888. volcanic-action, s. Geol.: The influence exerted by the heated interior of the earth on its external covering. ( Lyell .) [VULCANISM.] volcanic-ash, s. Petrol.: An ash-like substance derived from the attrition of volcanic scoria by the explosion of steam and gases in volcanic craters. The indurated volcanic ashes of early geological periods have had a similar origin. volcanic-bomb, s. Petrology : A name given to semi-fused, rounded ma es of rocks, of various mineral composition, sometimes ejected from volcanic craters during eruptions. [Вомв, ІІ. 2.] volcanic-breccia, s. Petrol.: A breccia formed by the consolidation of angular fragments of volcanic rocks. ( Lyell .) volcanic-dike, s . [DIKE, 8., II. 1.] volcanic-foci, s. pl. Geol.: The subterranean centers of action in volcanoes, where the heat is supposed to be in the highest degree of energy. ( Lyell .) volcanic-gla , s. Petrol.: The same as OBSIDIAN (q. v.). volcanic-mud, s. [MOYA.] volcanic-regions, s. pl. Geology & Geog.: Certain regions of the world throughout which volcanic and earthquake action specially prevails. They run in lines. The region of the Andes extends from lat. 43° South to 2° North; that of Mexico follows, then that of the West Indies. Another extends from the Aleutian Islands to the Moluccas and the Isles of Sunda, another from Central Asia to the Canary Islands and the Azores. There is one in the Grocian Archipelago, having its chief focus at Sant or in, known to have been active at intervals for two you sand years; then that of Italy and Sicily, having vents in Etna, Vesuvius, and Ischia. One region is in Iceland, with Hecla as its chief vent. Volcanoes are generally near the sea. Jorullo, in Mexico, is, however, an exception, being 120 miles from the nearest ocean.
