AbstractA comprehensive study was conducted from a semi-arid part of Yavtmal District, Maharashtra, India through combination approaches of geochemical modeling and its health consequences. The groundwater quality assessment shows that 55% of groundwater samples have the concentration of fluoride above the desirable limit. The high Na+/Ca+ ratio (>1.0) suggest the occurrence of cation exchange, which is further supported by Scholler’ chloro-alkaline indices. The geochemical modeling reveals that...

We report mineral compositions and bulk rock geochemistry of mafic dykes intruded in the western part of Bastar craton, comprising of Archaean Amgaon Group and Proterozoic Dongargarh Supergroup of rocks. Field relations show two distinct trends of these dykes which are almost perpendicular to each other but having similar mineralogical and geochemical characteristics. Dykes are mostly composed of pyroxenes, plagioclase and subordinate amount of amphiboles and Fe-Ti oxides (magnetite and ilmenite...

A qualitative approach, including geochemical and multivariate statistical approaches, is applied to evaluate the groundwater quality and human health risk, based on analytical data of 72 samples collected from a semi-arid region of eastern Maharashtra, India. The shifting of hydrochemical type from Ca2+–Na+–\({\rm H}{\text{C}}{\rm O}_{3}^{ - }\) to Na+–Ca2+–Cl− type was observed along different flow paths. The main controlling processes observed from the chemical characterisation of the groundw...

The Dongargarh Supergroup along with the basal Amgaon Gneissic Complex constitutes the northwestern part of the central Indian Bastar craton. In the present study, we report a new finding of a boninite dyke intruded in the Amgaon gneisses of this area. The dyke composed of mainly pyroxenes, amphiboles and subordinate amount of plagioclase. The higher contents of \(\hbox {SiO}_{2}\) (51–54 wt.%), MgO (12–14 wt.%), Ni (375–473 ppm), Cr (1416–1580 ppm) and very low \(\hbox {TiO}_{2}\) (0.2–0.4 wt.%...

In this paper, we, for the first time, report geochemistry of sandstone from Somanpalli Group from Pomburna area in the Eastern Belt of Pranhita–Godavari (PG) Valley, central India and studied to infer their provenance, intensity of paleo-weathering and depositional tectonic setting. Petrographic study of sandstones show QFL modal composition of arenite. Chemical results show high \(\hbox {SiO}_{2}\) and CIA but lower \(\hbox {Al}_{2}\hbox {O}_{3}, \hbox {TiO}_{2}\), Rb, Sr, \(\hbox {K}_{2}\hbox...

Remote sensing (RS) and Geographic Information System (GIS) is a powerful tool for managing and planning the mining activities and has an advantage of synoptic view, temporal capability and can observe the inaccessible areas. Open cast mining activities has direct impact on earth surface which can be studied and quantified using remote sensing technology. In the present paper, we examined the areal expansion of the coal mines and their impact on the surrounding area of Wani using RS and GIS tech...

Seasonal variations in groundwater reveal lesser concentrations of major ions except NO3 − during post-monsoon seasons in shallow aquifers as compared to deeper aquifers. The F− concentration from deeper aquifers is high in both seasons and shows a moderate positive relationship with weathering depth and is >5 mg/L in compound lava flow. Groundwater is mainly a Ca-HCO3 type in shallow aquifers and mixed type in deeper aquifers. Fluoride shows a positive correlation with pH, Na+, HCO3 − in shallo...

Hydrogeochemistry is an important tool for the evaluation of the effect of human activities on aquifer system. Sixty eight groundwater samples were collected from bore wells during pre- and post-monsoon from Nagpur , a fast growing city in India, to assess the spatial controlling processes of groundwater contamination using principal component analysis (PCA). Groundwater has variable total dissolved solid (TDS) and total hardness (TH) values classifying them from fresh to saline and moderately h...

The Amgaon mafic rocks occur as restite blocks within Amgaon gneissic complex which are metamorphosed upto amphibolite facies. Low Na2O+K2O (<4%), moderate concentration of SiO2, low differentiation index (DI<30) and solidification index (SI; avg. 32.18) are the characteristics of basic nature of these rocks. Na2O, MgO and CaO/Al2O3 values are similar to MORB (2.68%, 7.6% and 0.74% respectively) values. They show low-K tholeiitic characteristics which have evolved under ocean related tectonic en...
