... that movements along faults in this age range also generated strong earthquakes. Based on data of the location, composition, and age of travertines in the southeastern part of the Altai mountains, it is concluded ( Deev et al., 2017 ) that they are confined to active faults that limit the Chuya and Kurai...

Much of these thermobarometers was successfully tested by the authors earlier in the study of Kamchatka volcanism ( Dobretsov et al., 2016 , 2017 , 2019 ). The mineral crystallization depths in magma...
