Godhara Fm

Period: 
Neogene

Age Interval: 
Aquitania to Lower Burdigalian (Miocene)


Province: 
W.India Kutch Basin

Type Locality and Naming

SUBSURFACE. Interval 850-2049m in well SP-1-1. [Original Publication: Zutshi, P.L., Mittal, S.K and Shah, L. (1993) Lithostratigraphy of Indian Petroliferous Basins, Document IV, Kutch Saurashtra Basin, KDMIPE, ONGC Publication, pp 1-50.]

Lithology and Thickness

Shallow-marine marl. It consists of shale/claystone/limestone alternations and minor sandstones. 1200 m in well SP-1-1, thickness increases towards west.

Lithology Pattern: 
Shallow-marine marl


Relationships and Distribution

Lower contact

Unconformable with the Narayan Sarovar Fm (?; next older subsurface unit seems to be the Mit Nadi Fm). It is marked by sharp break in resistivity and gamma rays logs. It also coincides with the top of M. complanata.

Upper contact

Conformable with the overlying Chassara Fm. It is marked at the end of limestone/claystone alternations to dominantly final clastic of Chassara Fm.
