Lithogeochemical prospecting through stream sediments in Bela Ophiolite of Lasbela Area

Abstract EN

-Lithogeochemical investigation of sediments of active streams draining through Bela Ophiolite, from Lasbela area are presented.

This area consists mainly of ophiolites associated with sedimentary rocks of Jurassic-Cretaceous age .

Quantitative examinations of important immobile ·e lements such as Fe, Mn, Ti & Cr, and semi-mobile to mobile like Zn, Cu, Ni and Co have been carried out , These elements have anomalous concern rations in fine stream sediments in certain regions .

An attempt is made to demarcate the areas of possible occurrences of ore mineralization associated with the Bela Ophiolite based on statistical analysis of the geochemical data.

.

Statistical analysis and plots of data were employed to evaluate the distribution and interrelationship of these clements and coefficient of variation and correlation coefficients were calculated.

The suitability of the methods is discussed in relation with the arid climatic conditions ofsouthern Balochistan and the local geology
