Uttarlai Fm
Period:
Quaternary
Age Interval:
Plio-Pleistocene.
Province:
NW.India Rajastan-Barmer Basin
Type Locality and Naming
Lithology and Thickness
"Miocene to recent deposits of the Jagardia Fm and Uttarlai Fm comprise continental alluvial deposits. Recent alluvium and stabilized eolian dunes complete the basin fill." (Najman et al., 2018, Tectonics 37: 3970-3985). On Dr. Raju's chart, the Uttarlai Fm is shown with chalk incursions near top.
Lithology Pattern:
Sandstone
