The spatial distribution of minerals in nature is closely related to their genesis. Mineralogenetic reconstruction, including the reproduction ontogenesis and conditions for its implementation, highest form genesis minerals. A general methodical scheme mineralogenetic research proposed. evolutionary views modern mineralogy developments scientists two directions — phylogenesis are analyzed. On s...

Local geochemical background (LGB) has great importance for environmental assessment and management. In this study, 53 core soil samples were collected in 3 different sites with minimal or no human intervention to determine H.M. (Cr, Cu, Zn, Cd, Pb, Ni, Mn, As Sn) concentration pH. This study is aimed define the Geochemical Background of feralitic Vina Cameroon. determined using ICP-ES, Excel w...

Abstract The study examines about the red sand dune deposit locally designated as teri deposits; it is an omnipresent geomorphologic feature present in coastal region of Thoothukudi and Ramanathapuram districts Tamil Nadu, India. One inland outcrops located around Kuthiraimozhi village district Textural, mineralogical geochemical studies were carried out sediments its compact sandstone outcrops...

The Earth formed through accretion of planetesimals in 1–100 million years. Planetesimal impacts induce degassing, melting, and vaporization during accretion. The impact degassing, as well as the gravitational capture of the surrounding solar nebula gas, formed the proto-atmosphere on a growing Earth. The impact of heating and the blanketing effect of the proto-atmosphere resulted in the meltin...

-Multivariate statistical analyses of geochemical, mineralogical, and cation-exchange capacity (CEC) data from a Venezuelan oil well were used to construct a model which relates elemental concentrations to mineral abundances. An r-mode factor analysis showed that most of the variance could be accounted for by four independent factors and that these factors were related to individual mineral com...

In this study two small, but genetically related iron carbonate deposits Mačje Jame and Vranjski Potok, south west of Busovača (MBSM), located in the pre-Devonian metamorphic complex were investigated in detail. Analyses of the main chemical components, trace elements, REE, isotope composition of C, O, S, 87Sr/86Sr ratio of rhyolite, plot of REE normalized to CI chondrites and a microscopic stu...

The geochemical characteristics of sediments deposited within a channel-type reservoir situated behind the weir of a water mill on the River Liswarta (southern Poland) were studied in relation to land use in the catchment. The catchment in question is an agricultural one with large forest areas. The contamination of sediments with trace elements was assessed using the geoaccumulation index. The...

A chronological sequence of urban soils 3-92 years old was studied to determine the effects of time on morphogenesis, artifact weathering, and the geochemical partitioning of Pb. Key chronofunctions determined are an increase in ˆA horizon Development Index (defined herein based on soil color) and water-soluble Pb, and a decrease in pH and C/N, with increasing soil age. Key artifact weathering ...
