Abstract
Geochemical modelling is a constantly developing branch of Earth sciences, which facilitates solving of the wide spectrum of fundamental and application tasks. Its success depends on initial analytical data quality, which is controlled characterized factors. This paper aims to review use possibility of existing analytical databanks, composed of different sources and analytical methods derived data on geological objects. In terms of multi-laboratory experiment, research techniques consisted of quantitative chemical analysis results of reference samples set (RS) correlation to the data on single-laboratory measurements for the same RS using different methods. The research conducted revealed discrepancies between analytical data, which only depend on analytical techniques. This is particularly true for dissolution techniques, which predate ICP. Certain elements demonstrate unacceptable concentration deviations, which render analytical data inappropriate for geochemical modelling or other processing. The paper clarifies that geochemical modelling can utilize only specialized databanks, which meet following requirements: (1) strong geological background for the sampling locations and sample representability; (2) full spectrum major and trace elements chemical analysis conducted in a single laboratory using single method; (3) analytical survey conduction by means of modern, precision and most sensitive techniques; (4) supreme analysis validation, which grants reliability of initial geological information.
