Geologic Interpretation of the Rumoi Oil Field

Abstract

Rumoi oil field is one of the complicated structure in Hokkaido. Many unsolved problems remain here, especially regarding to the structure and sedimentation.
In this paper one interpretation is proposed, namely
1) stratigraphically the each horizon discussed, and
2) "Yudoro Facies" newly proposed, and
3) the facies being decided as one of the delta type affected by turbidity currents, and
4) accumulated in the sinking trough. Occasionaly Air-Photo is applied.
