Comments
Transform-margin-related intrusion of mafic-ultramafic plutons along major
continental-margin transform faults that formed after accretion of Samarka
subduction zone terrane.
Belt may have extended into Early Cretaceous.

Subduction-related granitic plutonism that formed the Umlekan continental-
margin arc.
Subduction-related volcanism associated with Uyandina island arc.
Belt extended into Middle Jurassic.
