Contrasting magmatic signatures in the Rairakhol and Koraput alkaline complexes, Eastern Ghats belt, India

Origin and magmatic evolution of the alkaline extrusive rocks of Neogene from Nehbandan-Assagie region, eastern Iran

The alkaline extrusive rocks of Neogene from Nehbandan-Assagie region, eastern Iran, include basanite, hawaiite, mugearite and benmoreite. Relatively low Ni and Cr contents and Mg-numbers of basanites are indicative of olivine and clinopyroxene fractionation from their relevant primary magma. Decreasing of CaO, TiO2, FeOt, HREEs and MREEs with increasing SiO2 indicate fractional crystallization...

Distribution of radionuclide in the forest soils (Western Ghats-India)

Background: The presence of radionuclides in the soil, measures need to be taken to minimize the radiation dose to humans. It is mostly gamma-emitting radionuclides that contribute to the radiation dose in long term behavior of these radionuclides in soil may determine the extent to which such countermeasures need to be applied. Materials and Methods: The activity concentration of these radionu...

Distribution pattern, zoogeographic similarities and affinities of montane herpetofauna of Southern Eastern Ghats, peninsular India

We examined the distribution pattern, across-site similarities and zoogeographic affinities of amphibians and reptiles in the montane zones (> 900 m a.s.l.) of the Southern Eastern Ghats mountains in peninsular India. We deployed long-term field surveys in four select massifs namely Jawadi, Shevaroys, Kolli and Sirumalai and generated herpetofaunal species lists. Based solely on our species occ...

Status Survey of Indian Golden Gecko, Calodactylodes Aureus (beddome, 1870) in Eastern Ghats, India

The Eastern Ghats are isolated hill ranges spreading across states of Andhra Pradesh, Odisha, Tamil Nadu and Karnataka in Peninsular India and covers an area of about 1750 km. It lies in 11 30 ́ to 21 0 N Latitudes and 77 22 ́ to 85 20 ́ E Longitudes. It is included under 6°C eastern highlands of the Deccan plateau and one of the biologically richest biogeographic zones of India (Rodgers et al., 2...
