Abstract

Revolution in the earth sciences mainly due to the formulation of plate tectonic or global tectonic hypothesis in early 70 's has provided better understanding of ore genesis and major tectonic settings. The hypothesis has given an impetus to the search of valuable economic minerals and rocks particularly in the Lasbela and Khuzdar districts of Baluchistan, Pakistan.

Igneous, sedimentary and metamorphic rocks of Mesozoic and Cenozoic ages dominate the lithostratigraphic exposures. Mineralizations are found in different tectonic settings; chromite, copper, manganese, magnesite in oceanic ophiolites and barite, lead, and zinc in the continental hot spots and rifts.

Beside minerals the area has significant potential for marble, granite, basalt, brecciated serpentinized rocks (known commercially as "Black Zebra "), quartzite, and variegated textured limestone suitable for use as building and decorative stones.

Zinc-lead deposits at Duddar, Lasbela district, are now in the proving stage. Australian company (PASMINCO). After further exploration these may turn out to be a world class ore body.
