Abstract
In the period 19691971, the hydrogeological studies were done in the area of the Kameoka basin, Kyoto prefecture. The conclusions are summarized as follows :
1) The geology of the Kameoka basin consists of Alluvial deposit, terrace deposit and Sino Formation that may correspond to the upper part of the Osaka Group.
2) The depth of the basement composed of the palaeozoic formation and of biotite granite was presumed from the result of gravity survey. The maximum value in depth situated near Kawarabayashi is approximately 280 meters under the ground.
3) The artesian wells in this basin are about 60 to 80 meters in depth and their discharge is about 2, 000 to 4, 000m3/day.
4) Though the quality of confined ground water derived from Sino Formation is bad, that from recharge flow of the Ooi river is excellent.
