| Abstract: | The Quaternary geology of the Cambay basin is studied with the help of aerial photographs and spot checking in the field. Sub-aerial denudational, fluviatile, aeolian and marine processes have produced the Recent deposits that cover the Cambay basin. Black cotton soils, lateritic soils and sandy loams, flood plain deposits, levees, swamps, salt waste, barrier spits, sand hills, undulating sands and flat sands have been identified. The trend of the fluviatile and aeolin deposits are in the NE-SW direction and the marine deposits trend NW-SE. The morphostructural distribution studied on the basis of tonal contrasts and drainage pattern indicates a general NE-SW pattern of structural trend in the Cambay basin and is in confirmation with the Aravalli and the Cutch structural trends. The Cambay basin area is a compound landscape wherein a mantle of youthful material fails to hide the dominant features of the underlying landforms. An attempt is made to relate the different geomorphic aspects to the underlying landforms. |
