Related to Geological fold: flexural slip, asymmetrical fold
formation of rock strata in which the strata are gently tilted in one direction. It is usually a limb of a broad and gentle uplift or of a depression of strata. Monoclines are especially typical of platforms, where they are confined to the limbs of anteclises and syneclises. An example of a monocline is the structure formed by Paleozoic beds from the southern slope of the Baltic crystalline shield toward the center of the Moscow syneclise; the inclination of the strata is calculated to be 2–2.5 m per kilometer of length.
