J. Hot Spring Sci.

This paper described on the hot and/or mineral springs in Kyoto Basin. Until some

dozen years ago, artesian flowing and shallow mineral springs are known around Kyoto

Basin. There are sulfuretted or sulfureous springs in the impregnated deposited and

radioactive water around Daimonji’ granitic body and along Hanaori active faults, re-

spectively.

A deep well until , m depth has been drilled at NE corner of Ohara sub-basin,

getting a hot spring. After then, some deep wells are drilled to get hotsprings, but higher

than hotsprings are known only along Katakibara active faults at Rakusai New

Town, of which area was su ered from Hyogoken-nanbu earthquake ( ).

subduction zone. The hydrated Peridotite is formed by addition of slab-derived H O (solid

arrows) beneath the forearc region and should be dragged on the slab by thesubduction of

oceanic lithosphere (Nishimura, ; modified from Tatsumi, ). AM-CHL : Amphibolite,
