780 recognition of all the features described above. Tne Sandy beaches show up as white strips, the tidal mudflats appear mixed areas of pink and blue and the lakes have recorded a deep blackksh blue shade. The marshes and the swamps are seen as blue are as. The basaltic cuestas show a paler shade of blue on the escarpments and a darker sha de of blue on the dipslopes. The ridge Cre stline of the Vikhroli-Ghatkopar range shows up as a fine line whereas the Kanheri range is seen as a very wide dark pink patch. The urban and suburban areea appear as very li ght areas with patches of pink representing vegetated hills. Open green turfs like the race course are seen as deep pink areas. The rocky beaches in the Juhu-Bandra stret ch show up as wavy blue lines along the sho reline. The salt fields are recognised by their white tone and the sandy spit at Ver- sova is clearly picked up as a fine, white projection into the sea. 3 MAP DATA The topographical maps or. the scale of 1: 63360 and the Town Guide Map on the scale of 1:25,000 wexe studied and these have added more local details while generally confirming the interpretation of the image ry. Rocky beaches can be clearly distingui shed from sandy beaches. The topographical contours not only give an idea about the relief dnd slopes but also indicate the attitude of the volcanic rocks through the landforms which are all structural landfor- ms. The tidal range is very clearly under stood from the maps and the drainage details over the mudflats are exceedingly clear. 4 FIELD DATA Field traverses for the collection of grou nd truth have provided data on the rock ty pes and their attitudes. Three low ranges of volcanic rocks trending NNE-SSW traverse the island producing promontories bordered by cliffs. The volcanics, dominantly basalts, strike NNE-SSW and have westerly dips rang ing from 11° to 23°. Trachytes and rhyolites are exposed in the Madh island and north ward. Tuffs are found in the Kanheri range along with agglomerate. Intertrappean sedi mentarles are exposed at a number of loca lities like Jogeshwari. Dykes of dolerites are met with in Trombay and in the Powai hills o Geomorphological field investigations alo- ^ the coast over the past ten years have revealed the recurrence of accentuated ma rine erosion in the area south of Versova. No other stretch along the coast has been or is undergoing erosion. Shetti and Subra- manyan (1985) have studied the spit which is trending southwestward from the mouth of the Malad creek and have attempted to simu late its growth through a computer progra mme. Field studies also indicate that the mul tistorey buildings have given rise to the densest concrete jungle in the Back Bay area in the southernmost part of the island and that urbanization is proceeding at a fast pace all along the coast in particular.
