Abstract
Around the quartz-diorite mass of the Tanzawa Mountainland, Central Japan, there are developed various contact metamorphic rocks., Of these metamorphic rocks, those distributed in the southern vicinity of the quartz-diorite include various schistose rocks which range from chlorite-green schists to amphibolites., The problem of heat-trandition in the formation of these contact metamorphic rocks is discussed from a view point of heat-conduction and the results are compared with the actual metamorphic facies in these rocks., Lastly the relations between the model cases and the geological condition are discussed.,
