【 摘 要 】

Thisstudy was carried out alongthewestern coastal parts of Balochistanfrom Gwadar east Bay to Jiwani.Thelocalanomalyofmajor,minorandtraceelementswerestudiedinthisarea.Zone-I(GwadareastandwestBay) indicates that calcium oxide, potassium oxide and titanium dioxide havehigher or average concentrations, while Zone-IIindicateshigheroraverageconcentrationsofcalciumoxide,titaniumdioxideandferricoxide.Traceelements zirconium, chromium, europium, strontium, and copper are in higher or average concentrations in both zones.Gwadar west Bay and Jiwani are intermediate in carbonate, which show a high degree of maturity, suggesting the high rate of weatheringinthesourcearea.Sedimentsamples fromGanz,Jiwani,andGwadareastBayrepresentthequartz-rich fieldsin this region. Gwadar east Bay has a positive correlation between aluminium oxideand potassium oxidewhich suggeststhatabundanceof potassiumoxideiscontrolledbyvariationinK-feldsparcontents.Apositivecorrelation between strontiumand calciumoxide suggeststhat strontiumisassociatedwith calciumoxideinbiogeniccarbonate materialinGwadarwestBay.Thepositivecorrelationbetween aluminiumoxide, copper,andzincinPishukan indicates that the abundance of these elements is due to limited silt and clay fractions present in sediments. Enrichment factor shows that chromiumandstrontiumare probably of anthropogenic origin in this region
