Judging from lithofacies, biofacies and sandstone percentage of the Kazusa group, two types, that is, primary and secondary, are recognized in its mode of sedimentation of sand. The secondary transported sands stand in some relation to gas potentiality because of their equigranular texture.

抄録

According to Dr. Ishiwada and present writers (1962), the Uvigerina akitaensis assemblage zone which makes practically the top of the Umegase formation disappears in the west side area of Chiba City and is replaced by sediments characterized by the cold shallow-water fauna.
In the Funabashi FR-18, the top of Umegase formation lies at 665 m below the surface and the shallow-water fauna appears at the Otadai and upper formations. From these evidences, the Kazusa group changes lithofacies and biofacies from southeast to northwest.
Judging from lithofacies, biofacies and sandstone percentage of the Kazusa group, two types, that is, primary and secondary, are recognized in its mode of sedimentation of sand. The secondary transported sands stand in some relation to gas potentiality because of their equigranular texture.
