This study provides an overview on the development of the guidelines and legislation related to soil contamination in Finland, with the main focus on geochemical baselines. The use of geochemical baseline surveys in the assessment soil contamination in Finland and in some other countries is briefly discussed and the current practices in Finland are presented. Finally, the geochemical baselines ...

Geochemical gene is a new promising concept proposed recently in the discrimination and traceability of geological materials also useful tool to recognize geochemical anomalies mineral exploration. Based on lithogenes LG01 LG03, can be classified into nine types LG_CR compositionally. With respect with 11 LG_CR, order eliminate lithological influence further narrow prospecting target area, tung...

Geochemical characteristics of greywacke and intercalated phyllites from Haveri and Dharwad block (long N 75° 10' to 75° 25' E and lat 15° 30' to 45° 00'S and (long 75° 05'E and lat S 15° 15' to 15° 35') of Shimoga basin have been studied to unravel the provenance and the tectonic setting of the greywackes. The greywackes are medium grained feldspatholithic and show presence of perthitic feldsp...

The Ingur alkaline granite massif and the associated Zr-Nb occurrence make up part of largest Mongolian-Trans-Baikal granitoid provinces. is composed arfvedsonite, biotite, alaskite granites. High content HREE determines low La/Yb n (2–7) value a negative europium anomaly (Eu/Eu*≈0.17). They are depleted in Ba, Sr enriched Nb, Ta, Zr, Hf Y. According to their geochemical properties rocks belong...

dens invaginatus is a rare developmental anomaly of teeth with complex root canal system morphology. the present case describes a peg shape maxillary lateral incisor with dens invaginatus (oehlers type ii), necrotic pulp, and an associated large periradicular lesion. nonsurgical endodontic treatment was performed with the aim of removing the blind sac with diamond bur under the use of operating...

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past environmental conditions as new tools continue to be discovered and developed. To date, organic geochemical proxies have been developed mainly for use in marine systems and are widely used in paleoceanography. In contrast, organic proxies have been less commonly used on lacustrine sedimentary records. One ...

Geochemical background is the basis of anomaly evaluation in mineral exploration and environmental investigation. However, value obtained from secondary media inevitably affected by weathering, transportation, sorting, which leads to depletion or enrichment chemical elements. This problem can be avoided geochemical mapping exposed crust. In this paper, more than 38,000 samples rocks data were c...

A two-dimensional model for colloid transport in geochemically and physically heterogeneous porous media is presented. The model considers patchwise geochemical heterogeneity, which is suitable to describe the chemical variability of many surficial aquifers with ferric oxyhydroxide-coated porous matrix, as well as spatial variability of hydraulic conductivity, which results in heterogeneous flo...
