Barite alongwith sulphide minerals occurs at several places in the southern part of axial fold belt of Pakistan. The deposits are confined within a lower-middle Jurassic rock sequence consisting of medium thick bedded limestones alternating with shales. In Lasbela area, allochthonous mineralized Jurassic blocks are embedded in a melange belt consisting of serpentinized ultramafics, doleritic sills and spilitic lava flows. Gacheri Dhoro deposit comprises of about 20 meters thick mineralized zone of interbedded limestone, shale and baritic rock. The precipitation of barite has taken place in the Jurassic sediments at structural highs by circulating connate brines or by mixing of meteoric water with ore fluids during late diagenetic-epigenetic stage of the host rock.
