“…The occurrence of different amphibole types from supra-and subsolidus reactions in an alteration parageneses in gabbros is also documented in other studies of oceanic (e.g. Vanko, 1986;Silantyev et al, 2008;Coogan et al, 2001) and continental rocks (Liu et al, 2009;Enami et al, 1999;McCormick & McDonald, 1999), and from experimental investigations (e.g., Currin et al, this issue; suprasolidus experiments: Khodorevskaya & Aranovich, 2016;Koepke et al, 2004;Chan et al, 2016). The passage of hydrothermal fluids through the crust in episodes of different temperatures and salinities is recorded by the formation of different amphibole types, equilibrating at progressively lower temperatures.…”

“…Amphiboles are volatile-bearing minerals, and an important phase in the inventory of the partial hydration of the oceanic crust. They have been proven to be an important Cl reservoir in altered oceanic crust (e.g., Ito et al, 1983;Straub et al 2003;Zhang et al, 2017a), since the same structural site that can host (OH)groups can accommodate Clanions (Vanko et al, 1986;Chan et al, 2016;Oberti et al, 1993). Amphiboles are stable over a wide range of temperatures, and their compositional changes provide useful information on the temperature of fluid-rock interactions that resulted in their formation (e.g., Ernst and Liu, 1998).…”

“…Однако критерий снижения глиноземистости Mg-Fe минералов как индикатора воздействия щелочносолевой составляющей флюида (реакция 6) не всегда применим в отношение роговых обманок. Дело в том, (Chan et al, 2016;Campanaro, Jenkins, 2017;Mueller et al, 2017), а роговые обманки с концентрациями Cl более 0.4 мас.% образуются в равновесии с рассолами (Chan et al, 2016). Реакция (8) сопровождается реакциями (1) и (3), ведущими к образованию калиевого полевого шпата.…”

“…Соотношения fH 2 O/fHCl = 0.37-0.71, оцененные на основе составов амфибола и апатита (Valley et al, 1990), соответствуют высококонцентрированным рассолам. Этот вывод подтверждается экспериментальными данными (Chan et al, 2016;Campanaro, Jenkins, 2017;Mueller et al, 2017), которые указывают, что амфиболы с содержаниями Cl более 0.4 мас.% образуются в равновесии с истинными рассолами. Отношение K/(K + Na) в амфиболе более 0.6 (рис.…”
