“…Halite from reaction zones between intrusive magma and salt rocks is characterized by abundant solid chloride and brine inclusions, spatially associated with dense CO 2 inclusions (Fig.5). CO 2 -rich phase occurs as intergrowth with chlorides and in isolated monophase Kochumdek deposit contain rare samples preserved contact metamorphic halite while generally metamorphic halite was removed by dissolution during intensive late hydrothermal activity (Warren, 2016). Abundant CaCl 2 solid inclusions were found often in intergrowth with KCaCl 3 solids.…”

Anhydrous chlorides-CaCl 2 , and KCaCl 3 (chlorocalcite) were identified as mineral inclusions in halite from the Siberian Large Igneous Province at the contact of magmatic intrusions and evaporates. Chlorocalcite was also found as daughter mineral in polyphase hypersaline inclusions. While Raman spectra of KCaCl 3 (chlorocalcite) in natural inclusions are similar to spectra of synthetic analogue, the Raman spectra of natural CaCl 2 do not correspond to the published Raman spectra of synthetic CaCl 2. Simulations of Raman spectra using ab initio density-functional theory (DFT) allowed us to calculate the spectra of individual polymorphs of CaCl 2 and to discriminate anhydrous CaCl 2 phases in natural inclusions and synthetic CaCl 2. In the spectrum of the Pbcn polymorph of CaCl 2 twelve different peaks could be identified at 74,

“…Pargasite has not been previously reported at Ertsberg, but it has been reported as a prograde phase in metacarbonates (e.g. Proyer et al (2008); Satish-Kumar et al ( 2001); Thu and Enami ( 2018)) and it may form during metamorphism of sodic evaporite-bearing sequences (Pirajno, 2018;Warren, 2016;Zhu et al, 2015). All these observations point towards the formation of pargasite during prograde metamorphism (Stage 1).…”

—For a multirate approximation, we have determined the dynamics of rock heating by a magmatic-fluid flow in a flat permeable zone cutting the cratonic lithosphere of the Siberian Platform from a magma chamber at a depth of 50 km to the Earth’s surface. This dynamics is compared with the dynamics of infiltration metasomatism in a three-layer lithosphere section: (1) harzburgitic mantle (depth 50–40 km), (2) crystalline basement (39–7 km), whose composition was simulated by the section of rocks hosting the skarn deposits of the Aldan Shield, and (3) platform cover (6–0 km), with its simplified rock compositions specified on the basis of the rock compositions in the southern and northern parts of the trap area of the Siberian Platform. Numerical modeling of the metasomatic transformation of rocks was performed in a multireservoir flow reactor, using the Selektor software. The initial composition of fluids in a magmatic source varied from highly reduced (water–methane) to ordinary (water–acid) (lg pO2 from –13.0 to –12.0). The obtained balances of the interacting phases show no significant change in the mass of aluminosilicate rocks in the mantle and Earth’s crust sections and a significant loss of their mass under replacement of carbonate and sulfate deposits.
