Abstract

Summary

As a result of radiometric-material data factorization, a basis was obtained for using alpha and beta radiometry data for detailed facial and genetic subdivision of sedimentary deposits of Runovschyna Area (Poltava region, Ukraine). It is most appropriate to use the results of SAA for lithologic subdivision of geological profile. Here, the SAA and SBA together show a high positive correlation with the Al2O3, K2O content, which are the major components of the clay components, whereas with SiO2 (typical of sandy sediments), this factor has a low but negative correlation. It is also possible to use factorized radiometric parameters, with their contrasting behavior (increasing of SAA and decreasing in SBA) to evaluate: dolomitization – with help of high factor loadings of “diagnostic” components −SiO2, +MgO, +CaO; facial (−TiO2, −Na2O, −K2O, −S) and physic-chemical weathering conditions (−Mn, −P).
