SEDIMENT CHEMISTRY OF RIVER JHELUM IN KASHMIR VALLEY (INDIA): AN INDICATIVE OF WEATHERING

Javid A Sheikh

Abstract


Eleven sediment samples have been analyzed to monitor the sediment chemistry of River Jhelum, Kashmir valley, India. The parameters of river Jhelum showed remarkably wide ranges: SiO2 concentration ranged from (52.3%-78.7%), Al2O3 concentration ranged from (9.2%-14.45%), CaO concentration ranged from (1.68%-23.37%), Fe2O3 concentration ranged from (3.6%-8.46%), MgO concentration ranged from (0.6%-3.43%), Na2O concentration ranged from (0.7%-1.5%), K2O concentration ranged from (0.6%-1%), MnO concentration ranged from (0.3%-0.6%), TiO2 concentration ranged from (0.7%-1.7%), P2O5 concentration ranged from (0.36%-0.6%). River Jhelum is characterized by moderate chemical index of alteration (44-79), reflecting moderate weathering in the source area/catchment of the river. The K2OFe2O3Al2O3 triangular plot of the samples demonstrate residual clay formation and Al2O3(CaO+Na2O)K2O triangular plot demonstrate trend of plots towards the Al2O3 apex and are away from PAAS, thus booth triangular plots indicate moderate weathering at the source. Comparing River Jhelum sediment data to the pos
