Abstract
The aim of this work is to show commonly used procedures and methods for limestone analysis. The samples were measured with Inductively Coupled Plasma with Optical Emission Spectrometry (ICP-OES) for chemical compositions determination. For these measurements, the samples were decomposed by dissolving in acid, melting into solution and decomposed by microwave. Due to the time and financial demands of these analyses, there were an effort how to find a satisfactory method providing sufficient results with less time and financial demands. The X-ray diffraction (XRD) method was first tested, followed by X-ray fluorescence (XRF). Samples were measured in powder and melted into pearls. The evaluation was carried out by using of the Fundamental parameters method and by means of instrument calibration. The method of combustion elemental analysis was selected to determine of the sulfur content.

Summary
The limestone has been used by humans for several thousand years, and there still grow the possibilities of processing and using of this raw material. Most limestones originated in the seas and their genesis was associated with rockforming organisms. The main conditions for the formation of limestone were the climate and the absence of clay or sandy material. In nature, it is predominantly as minerals of calcite and aragonite. Calcite is usually sediment from organic origin. Aragonite secreted from solutions at higher temperatures or in the presence of sulfates. It may have a biogenic origin from the shells of some molluscs [1]
