Neotectonic transverse structures of mobile belts: A study of an example of their deep tectonic relationships in the Koryak region, northwest Pacific margin
The type transverse structures that trend across mobile belts and into the platform of eastern Europe have in the past been investigated by traditional geological and geophysical methods. Now, however, these methods are becoming integrated with recently developed neotectonic studies that use aerial and Earth-satellite photographs and morphometrically and morphographically processed topographic maps. These integrated studies, both traditional and neotectonic, have revealed deep-seated transverse tectonic features that extend down to and include the basement. Thus, starting from geomorphic anomalies at the Earth9s surface, such methods have proved useful in deciphering the deep as well as shallow transverse structures of the Koryak region. This region includes not only transverse Paleozoic and early Mesozoic basement structures but also late Mesozoic and Cenozoic longitudinal structures in which relics of the older transverse structures survive. It also includes new transverse structures that have appeared since the longitudinal Koryak mobile belt evolved.
