Geography
Country:Japan State/province:Gokase
Coordinates: 32.6° North, 131.2° East (view map)
Paleocoordinates:
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period: Silurian Epoch: Llandovery - Ludlow
Stage: Telychian - Gorstian 10 m.y. bin: Silurian 1 - Silurian 2
Key time interval: Telychian - Gorstian
Age range of interval: 438.6 - 425 m.y. ago
Stratigraphy
Formation:Gionyama Member:Middle
Stratigraphic resolution:group of beds
Lithology and environment
Primary lithology:massive lithified conglomeratic "limestone"
Secondary lithology: lithified "shale"
Lithology description: limestone conglomerate beds
Environment:slope/ramp reef
Geology comments: Limestone conglomerate intercalated with thin lenticular beds of tuffaceous shale and sandstone. The limestone conglomerate yields abundant corals with various other fossils, such as stromatoporoids, crinoids, bryozoans, and gastropods. Kido and Sugiyama (2007a) suggested that the limestone conglomerate of the Middle Member might have derived from shallow-water reehrl limestone, and was transported and deposited as the result of a debris flow or storm
action on a reef slope or along a reef front.
