At the next stage, in the interval of 285–278 Ma the shoshonitic Low Selenga suite made up of monzonite, syenite and alkali rich microgabbro was formed; this suite was followed...

...-eclogitic conditions. Due to the abundance of serpentinites and to their contrasted relationships with the metamorphic rocks, the Escambray massif and the Zaza Zone are well-suited areas for the study of serpentinites in a convergent settings. In the Zaza Zone, Cu51, Cu54, Cu55, and Cu56 samples...
