Benthic Diatoms in River Influenced By Urban Pollution, Bhavani Region, Cauvery River, South India
The present-day study assesses diatom communities in river with relation to environmental conditions. Diatoms are susceptible to environmental conditions in river and their distribution is mainly governed by the physicochemical composition of the water. Diatoms and water samples were collected in 5 locations during summer season (May 2012). Analysed data were interpreted and the results are rep...
متن کاملCoralline Algae From The Ninniyur Formation (Thanetian)Of The Cauvery Basin, South India
The Palaeocene sediment of the Tiruchirapalli area shows presence of some elements of geniculate and non-geniculate coralline Algae. Four coralline algal species are recorded from this Formation (Thanetian age). Two of the described species belong to Sporolithon. Of the remaining two, one is assigned to Coralline, while the other one is indeterminate, being referred to the subfamily Melobesioid...
متن کاملRadioactivity and radiation hazard assessment of Cauvery River, Tamilnadu, India
Background: Natural radiation is constantly present in the environment and is emitted from a variety of natural and artificial sources. It affects human body and environment. Materials and Methods: The activity concentrations of 238U, 232Th and 40K have been determined by Gamma ray spectrometer with an HPGe detector in sediments of Cauvery River, Tamilnadu, India. Results: The absorbe...
متن کاملGeochronologic constraints across the Main Central Thrust shear zone, Bhagirathi River (NW India): Implications for Himalayan tectonics
The Main Central Thrust shear zone is the dominant crustal thickening feature in the Himalayas, largely responsible for the extreme relief and mass wasting of the range. Along the Bhagirathi River in NW India, the Main Central Thrust is several kilometers thick and separates high-grade gneisses of the Greater Himalayan Crystallines from Lesser Himalayan metasedimentary rocks. Th-Pb ion micropro...
متن کاملEclogite-facies metamorphism preserved in tectonic blocks from a lower crustal shear zone, central Transantarctic Mountains, Antarctica
In the Geologists and Miller Ranges of the central Transantarctic Mountains, mafic and ultramalic tectonic blocks occur in an Early Cambrian amphiboliteto granulite-facies lower crustal transpressional shear zone. Mafic blocks consist of garnet + clinopyroxene symplectite + hornblende + plagioclase + quartz + ilmenite f orthopyroxene f biotite;mineral compositions in these blocks generally refl...
