Item Terrain analysis and hydrogeochemical environment of aquifers of the southern west coast of Karnataka, India(2012) Honnanagoudar, S.S.; Venkat Reddy, D.; Mahesha, A.Dakshina kannada district is situated in peninsular region. The peninsula is composed of geologically ancient rocks of diverse original and most of them have undergone metamorphism. The early Precambrian tonalitic gneisses invaded by granites, granulites and dolerite dykes. Granulites are mostly restricted to areas south of Mangalore. High grade alumina rich (corundum bearing) metamorphic schists have been encountered and younger alkaline intrusive rocks like Aegerine syenites have been reported. There are five rivers and estuaries. Number of lineaments cut across each other and some lineaments are parallel to each other. The Arabian sea class is the largest among other land cover features in the study area. The river/tidal creek land cover appear as long irregular and sinous in outline. Mulki river, Netravati river, Gurupur river at southern terrain. The qualities of groundwater at sandy aquifer are good, lateritic/weathered gneissic rocks it is sweet. © 2012 CAFET-INNOVA TECHNICAL SOCIETY.Item A geological and geotechnical investigation of some rocks in Trivandrum area, Kerala, India(CAFET INNOVA Technical Society 1-2-18/103, Mohini Mansion, Gagan Mahal Road, Domalguda, Hyderabad 500029, 2015) Anand, R.S.; Venkat Reddy, D.In the Indian stone industry, possessing huge reserves of about 1,690 million cum dimensional stone deposits, geological and geotechnical parameters of commercial rock deposit plays a significant role in the economic exploitation of quality commercial rock deposits. The success of the commercial stone industry solely depends upon the availability of large reserves of defect free raw materials. An attempt is made here to study the geological and geotechnical properties of different rocks from Trivandrum area, Kerala. A variety of rock samples from different parts of Trivandrum are subjected to study petrographic, physical and strength parameters. Geological studies reveals that inherent geological discontinuities in rock deposits like multiple joints, weathering, foliations and variations in color of the rocks etc. lead to huge wastage of resources, because such rocks are not suitable for any engineering purpose. The geotechnical studies conducted gives an idea about the physical and strength properties of the rocks. The result of the study gives the rock which has maximum favorable properties for use in construction engineering applications, out of the available ones in the study area. © 2015 CAFET-INNOVA TECHNICAL SOCIETY.
