Abstract

Modes of occurrences of metamorphic and granitic rocks of the Atokura Nappe are studied to elucidate the geological structure of the Atokura Nappe. The examined klippes are exposed in the Minano-machi and Yorii-Ogawa-machi areas of the north-eastern parts of the Kanto Mountains. Small geologic bodies of metamorphic and granitic rocks of less than 1 km in size are tectonic blocks in fault contact with sedimentary rocks and quartz diorite. Many tectonic blocks consist of smaller tectonic blocks which were sheared and weakly metamorphosed. Geologic bodies including many tectonic blocks are also bounded by faults. Hence, the Atokura Nappe consists of various types of tectonic blocks which were formed in a root zone by contraction tectonics before the Nappe formation.
