Abstract:
The aim of this paper is to give a proper overview of scanning methodology, scanned drill core samples, demonstrate sedimentary rock samples as a perfect geological material for digital scanning methodology, which helps to archive important geological information, to select necessary texture and structure designs of rock materials, and to follow its peculiarities. The scanning method-ology is a perfect tool for observing and assessing all rock samples for new investigations or layer-to-layer mining planning and selecting the best mining-geological conditions and even pattern selection for decorations in architectural works. The described and used methodology is available and free for everyone: researchers, mining engineers or mining development companies as well as geologists and others. Carbonate rocks are mined worldwide but only in Estonia, one of them – limestone is a national stone, thus mainly scanned limestone samples were used in this research. As a result, all drill core rock layers are accurately identified and the most important of them are described in detailed laboratory study. The findings are highly relevant for local and regional stratigraphy and represent the Ordovician Period in Baltic States.
