The evolutionary stages and petrology of the kekuknai volcanic massif reflecting the magmatism in the backarc zone of the kuril-kamchatka island arc system. Part II. petrologic and mineralogical features, petrogenesis model

The space-time relationships between volcanic associations of different alkalinities: The Belogolovskii massif in Kamchatka’s Sredinnyi Range. Part 1. The geology, mineralogy, and petrology of volcanic rocks

“…magmatic differentiation controlled by the potassic fluid, as envisaged for the Kekuknai massif [Koloskov et al, 2013].…”

“…At the same time, there are geo logical features where volcanic rock associations of differ ent petrogeochemical series occur together; the relation ships among these are of interest for magma petrogenesis. In particular, the Sredinnyi Range contains several fea tures of this kind, viz., the Uksichan caldera, and the Kekuknai and Belogolovskii volcanic massifs [Antipin et al, 1987;Flerov et al, 2009;Koloskov et al, 2011Koloskov et al, , 2013. The present paper reports on the results of petro logic surveys of the Belogolovskii massif that we con ducted in the network of the first Belogolovaya and Moroshka rivers in 2005 and 2007, as well as using data from [Volynets et al, 1990b] and materials from a geolog ical survey.…”
