“…These are exposed in a north‐south‐oriented 200‐km‐long and 30‐ to 40km‐wide zone in the southern part of the Sredinny Range (Figure ). The Sredinny Complex is either part of the Okhotsk block (e.g., Bindeman et al, ; Konstantinovskaya, ; Parfenov & Natal'in, ), or a separate West Kamchatka microcontinental block (Bogdanov & Chekhovich, ; Chekhovich et al, ; Filatova, ; Zonenshain, ), or represents the metamorphosed equivalent of the terrigenous sediments of the Asian continental margin (e.g., Hourigan et al, ; Kirmasov et al, ; Shapiro & Solov’ev, ). The structurally lowest and highest‐grade unit, the Kolpakova Group, consists of Lower to Upper Cretaceous granulite‐ and amphibolite‐facies gneisses and migmatites (Hourigan et al, ; Tararin, ; Vinogradov et al, ; Figure ).…”
