Named by: Not recorded
Type locality: Bela ophiolite-and-thrust belt, Lasbela26.2268°N, 66.3113°E
Thickness: 3000+ m
Lithology: Ultrabasic, basic and intermediate rocks — altered pyroxenite and serpentinized peridotite — with rare granite (only as conglomerate pebbles).
Synonyms: Not recorded

The Bela ophiolite of Lasbela — a large obducted slice of ocean floor marking the India–Eurasia suture, and a chromite host.

Southern ophiolite belt marking Western Indus Suture. Less complete than Muslim Bagh but similar origin.

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

The serpentinized ultramafics host chromite (with associated manganese), in the Bela ophiolite belt.

Remarks

A major obducted Neotethyan ophiolite of the Bela–Zhob–Waziristan suture in Lasbela, marking the Cretaceous boundary between the Indian and Eurasian plates along the western Indus suture.
