Unit summary

Rank: formation
Status: Published
Age: Paleozoic · Silurian–DevonianSilurian to Devonian (correlation)
Named by: Badshah et al. (2000)
Type locality: Spinghar (Safed Koh) Range, NW Pakistan–SE Afghanistan border region.
Thickness: Not recorded
Lithology: Siliceous, white to greyish-white, hard dolomite (up to ~19 wt% MgO) with dolerite intrusions; talc/soapstone along fractures and intrusive contacts.
Synonyms: Not recorded

A Siluro-Devonian siliceous dolomite of the Spinghar (Safed Koh) Range on the NW Indian-plate margin, introduced by Badshah et al. (2000). White to greyish-white and hard, it overlies the Spinghar Crystalline unit, is cut by dolerite intrusions, and carries talc (soapstone) and silver-rich lead-copper mineralisation along fracture zones. It is correlated with Silurian-Devonian rocks of the Khyber Agency.

Band colour = period; texture = dominant rock type. Lines between bands mark the contact type. 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.

Economic significance

Metals & minerals

Hosts talc (soapstone) along fracture zones and mafic-intrusion contacts, and silver-rich lead-copper mineralisation in the western Spinghar (Neemtota).

Remarks

Overlies the Spinghar Crystalline basement and is disconformably(?) overlain by the Spinghar Quartzite; forms south-facing cliffs in the Spinghar nappe (Badshah et al. 2000).
