Figure 4-2: Geology <strong>of</strong> <strong>the</strong> Project Area<br />
The geographical formation <strong>of</strong> Saurashtra region is <strong>of</strong> volcanic origin, hence <strong>the</strong> soils <strong>of</strong> Rajkot<br />
district are derived from trap rock. The land <strong>of</strong> <strong>the</strong> project region that falls in Rajkot district is<br />
mainly divided into two types:<br />
Salty land is mainly <strong>the</strong> type <strong>of</strong> land in Morbi and Maliya and black, loamy soil is mainly present<br />
in Jetpur and Dhoraji talukas. The soil <strong>of</strong> <strong>the</strong> project region that falls in Jetpur taluka is red soil. In<br />
Junagadh district, <strong>the</strong> soils are formed partly from sedimentary rocks and partly from igneous<br />
rocks. They are calcareous in nature, rich in potassium content but deficient in nitrogen and<br />
humus. The main types <strong>of</strong> soils in <strong>the</strong> district are black, medium black, alluvial soil in <strong>the</strong> lowlying<br />
area, calcareous and brackish. The black soil is found in parts <strong>of</strong> Vanthali, Manavdar and<br />
Keshod talukas excepting <strong>the</strong> Ghed area. Most <strong>of</strong> <strong>the</strong> villages in Junagadh, Malia talukas have<br />
medium black soil. The alluvial soil in <strong>the</strong> low-lying area, known as ‘Ghed’, comprises parts <strong>of</strong><br />
Keshod, Mangrol and remains inundated during monsoon. The brackish soils are mostly found<br />
near <strong>the</strong> coastal belt <strong>of</strong> Mangrol, Malia and Veraval talukas and represent <strong>the</strong> degeneration <strong>of</strong><br />
