2.4 Case Study:
2.4.1 Timba, Gujarat:
220.127.116.11 Aim To Study:
• To understand the condition of basalt quarry
• To understand the ecological restoration process of basalt quarry
Timba is located about 110km, south east of Ahmedabad, Gujarat, India. This area is famous for the quarry. Currently quarry has been stoped there, but it disturbed the natural ecology environment, which was present there before quarry. Because of quarry barren land and degraded land is left, which has no meaning. The soil condition also degraded there, which effect the growth of trees. 41 hectares is the total area of exhausted quarry. The M/S Prabhakar P.Bhagwat associate, a landscape firm have been taken the responsibility to improve the…show more content… Other plants grasses and shrubs not originally planted made their appearance in third and fourth year, and at the eight year full process is complete. The land contours are also studied to divert the rainwater. The lake was formed there by rainwater with popular varieties of fishes. Now, the entire area has become a natural environment with several varieties of insects, fishes in lake and birds.
18.104.22.168 Conclusions of Timba study:
Timba basalt quarry restoration is a best example of ecological restoration. The circumstance in timba before restoration were quite challenging and it took eight years to get green , this evidence makes it clear that ecological restoration will be a key element not only of conservation but also for sustainable development.

3.1 Hydrogeology study of Vishrantwadi Lake:
The hydrogeology study confirms the presence of basalt rock at the bed of Vishrantwadi Lake. Basalt rock is aphanite (fine grained), igneous rock with generally 45% silica (SiO2). Basalt rock is rich in magnesium and calcium. And low in alkali oxides. If we compared with the other rock found on earth surface, basalt weathering is relatively high. Chemical weathering also releases readily water-soluble cations such as calcium, sodium and magnesium, which give basaltic areas a strong buffer capacity against acidification.in basalt rock, calcium released by
