Band colour = period; texture = dominant rock type. Lines between bands mark the contact type; dotted = no contact recorded in the sources (not a claim of conformity). True scale makes height ∝ recorded thickness; hatched = thickness not recorded. Ages approximate, for ordering.

This unit (highlighted) within its province column; faded ends continue above and below. Line style marks the contact type.

Geological significance (1)

Malkani (2019) records the Early Paleocene Sangiali Formation as a bivalve-, nautiloid- and gastropod-bearing limestone and shale carrying Deccan volcanic dust, deposited during the earliest Paleocene marine transgression as the basal unit of his Sangiali Group (Sangiali-Rakhi Gaj-Dungan). The Deccan-dust association is a distinctive K/Pg-boundary marker in the western Sulaiman/Kirthar basins.

Reviewer confidence: medium

Every fact on this page is source-cited. This entry is part of the peer-archived Pakistan Stratigraphy Dataset (doi.org/10.5281/zenodo.21363991, CC‑BY‑4.0).

Lexicon status: Appears in a single-author Geological Survey of Pakistan memoir (Malkani & Mahmood 2017), not cross-confirmed against the Shah lexicon. The Stratigraphic Committee of Pakistan is largely inactive, so documented provenance — not formal ratification — is the available signal.
