In the paper are shown results of the mineralogical-petrographical examinations of the trepel as a peculiar sedimentary rock of biogenetic origin from the Suvodol village near Bitola city, Republic of Macedonia. According to the microscopic (in polarizing translucent light), SEM, chemical, X-ray powder data was determined that examined trepel is composed mainly of opal (of biogenetic origin) as well as quartz, feldspars (plagioclases, K-feldspars), illite-hydromicas, chlorites of minor importance. Further examinations are in progress because the aforementioned results are based on one randomly selected trepel sample.
