Sileks – a secondary quartzite mine, located in the western part of the Kratovo-Zletovo Volcanic area, between the villages of Playsters and Borovic. It is essentially a Caldera in a volcanic-sediment complex, which includes various rock masses (Andesites, tuffs, etc.). From a genetic point of view, secondary quartzites are metashamous creations created during postgokal activities, on fumarolco-solpress phases in the time of myocal-plillene epochs. The quality of secondary quarzits varies, because the silkship bodies are not a homogeneous environment, but works with variable forces. The poorly strengthened spaces have 60% of Cibo, and intense silfe2 Cyrants more than 90%. Lit.: Milorad Stojanovic, deposits of non-metallic mineral resources in Macedonia, Skopje, 2005. T. Sir.
