Aeolian deposition of Arabia and Somalia sediments on the southwestern continental margin of India
MetadataShow full item record
Kaolinite, smectite, illite and chlorite as major clay minerals and palygorskite and gibbsite in minor quantities have been recorded from the slope of southwestern continental margin of India. Contribution of kaolinite, smectite and gibbsite is from peninsular India through fluvial discharge. Since formation of palygorskite calls for an arid and hot climate and saline conditions, occurrence of this clay mineral in the sediments of the study area documents aeolian sediment contribution from Arabia and Somalia by the Arabian northwesterly winds.
