Geology of Kent into northern France. The fold arises from the continuing Alpine orogeny and results in the general northward dip of the rock strata in most of Kent. There are extensive spreads of coastal and estuarine alluvium on the Thames Estuary coast, in the low ground surrounding the Isle of Thanet and across Romney Marsh. Alluvium also floors the valleys of the River Medway and Stour. 'Clay-with-flints' is a commonly occurring deposit across the North Downs which is a product of periglacial conditions during the last ice age. Loessic deposists, of aeolian origin i.e. windblown, are common in east Kent, especially on
History of the British salt tax in India years. The Rann of Kutch is an extensive marshland which is cut off from the rest of the Indian subcontinent during monsoons when the seas inundate the low-lying areas. However, when the sea water evaporates during summer, it leaves behind a crust of salt which accumulate as salt pans. This salt is collected by laborers called "malangis". On the east coast, salt could be obtained extensively along the coast of Orissa. The salt produced by the salt pans called "khalaris" in Oriya is of the finest quality in all India. There has always been a demand for Orissa salt in
