Panvel Fm
Period:
Paleogene
Age Interval:
Late Oligocene
Province:
W.India Mumbai Offshore
Type Locality and Naming
Found on Bombay High DSC Block
Synonyms: The carbonate Panvel Fm of Zutshi et al. (1993) is considered as junior synonym of the more clayey Alibag Fm. But listed separately here to be consistent with NDRDGH.gov stratigraphic chart for Mumbai offshore.
Lithology and Thickness
NDRDGH.gov Mumbai stratigraphic chart indicates carbonate; but Raju's column had shown as clay-dominated.
Lithology Pattern:
Shallow-marine marl
Relationships and Distribution
Lower contact
Unconformably overlies the Mukta Fm
Upper contact
Unconformably overlain by the massive limestone of the Ratnagiri Fm. Over another part of the Bombay High DCS Block, the limestone of the Bombay Fm overlies the Panvel Fm
