Lithology and Thickness
Limestone build up in the form of muddy foraminiferal-algal banks. 43m on Raju's chart.
Lithology Pattern:
Reef limestone
Relationships and Distribution
Lower contact
Underlain by the sandstone of the Panna Fm.
Upper contact
Disconformity (late-Ypresian and earliest Lutetian missing), then overlain by the Bassein Fm carbonates.
Regional extent
