Kandla Fm

Period: 
Neogene

Age Interval: 
Middle Miocene - Recent


Province: 
W.India Kutch Basin

Type Locality and Naming

SUBSURFACE. Interval 0-2110 m in well Kutch - A. [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

Claystone. Consists of streaky claystone with calcareous concretions and thin bends of poorly fissile silty shale. The formation has shell fragments and pyrite in well Kutch-A. 365 m thickness in well GK-29A-1 and more than 2000 m in Kutch-A and GKH-1 wells.


Lithology Pattern: 
Claystone


Relationships and Distribution

Lower contact

In the subsurface the lower boundary to Mitti Nadi Fm is marked by the log break and coincides with seismic marker S-7. Regionally, next older formation is either the Chassara Fm or the local Kankawathi Fm.

Upper contact

Marked by sea bottom in Kutch offshore. Diachronous; and most is not present nearshore.
