New data was acquired for Korosten Pluton (Ukrainian Shield) in order to develop specialized databank, which would meet following requirements: (1) sufficient geological background of sampling points selection, their representativeness and high level of sampled rocks petrographic study; (2) wide range chemical analysis including major and a set of litho- and chalcophile trace elements with different values of effective ionic radius and mineral/melt distribution coefficient using single technique in a single laboratory, if possible – simultaneously; (3) analytical survey conduction by means of modern, precision and most sensitive techniques; (4) high level of analysis validation, which grants reliability of initial geological information. This publication presents results of analytical data quality control: (1) values of systematic errors are minimal and don’t exceed relative standard deviation; (2) values of relative standard deviation don’t exceed 10% at lev el of 5 LOD for most of the elements; (3) trace elements concentrations usually exceed LOD value by significant margin; (4) relative standard deviation values of all major elements in the vast majority of determinations don’t exceed 10% limit. As 2-4 requirements for special databanks are met, analytical data obtained on Korosten Pluton can be successfully utilized in development of databanks, which are targeted at geochemical modelling.
