抄録

The Suzuka Granite pulton occupies the backborn area of the Suzuka Mountains, southwest Japan. It has an extent of 3〜9km (E-W)×13km (E-S), convex by arched southeastward, being intruded into the late-Paleozoic to Mesozoic formations of the Mino belt. The northern half of the pulton consists of biotite granites of following three major rock-types, the Yunoyama-type, Happudani-type and Kanzaki-type, and subordinate Hatomine-type. Two intrusive stages are recognized for them. The Suzuka Granite is associated with the porphyries, which are related to the late-Cretaceous felsic volcanism (Koto Rhyolites) forming a cauldron. The Suzuka Granite is considered to an outer most part of the ring complex in the south of Lake Biwa.
