Quantitative petrography: approaches and applications

Quantitative petrography is a scientific and industrial direction of geology, which made huge progress due to developments and inventions in information technology and optics in the last decade. This article is introducing the modern and scientific directions of quantitative petrography and describes their current state of art as well as methodical approaches and their application. The research objects of quantitative macropetrography are hand specimens, borehole cores and polished tiles, and of micropetrography are thin and polished sections of rocks samples, splitted rock surfaces and immersion preparations. The goal of the research is to develop and present new methodological approaches of digital microscopy for the analysis of ores, rocks and minerals, as well as to investigate the morphological image analysis capabilities for the transforming from the classical description methods to quantitative petrography.
