Геоморфологія і сучасні екзогенні процеси Ясниського кар'єру

Abstract

On the base of field investigations the geomorphologic map of quarry in the scale of 1 : 2 000 has been created. Yasnys’kyi quarry contains following types of man-made relief: excavated, poured, inwashed (hydraulic-filled), and excavated-poured. Among excavated forms are quarry walls and bottoms. Limestones almost everywhere wire quarry walls. Maximal height is observed in the northern-western part of the quarry (25-29 m). The quarry bottoms form larger part of investigated territory. The majority of quarry bottoms are filled by water (two man-made lakes). To poured forms the old mining-falls outside the quarry belong. Within the quarry are also three inwashed falls: one of them is situated near the lake; another two are situated in the southern part of quarry. Excavated-poured relief is presented by fragments of quarry-walls which where cut, strewed up and transformed into earth-road on slopes and bottom of the quarry. There are two types of processes within the quarry: gravitational and water-erosion. Among gravitational landslides and crumbles are predominant. Landslides are observed on some quarry walls (for example on the highest wall and non-turfed walls). Crumbles are dominated in the northern and northern-eastern parts of quarry. The main water-erosion forms in the quarry are presented by erosion furrows and flushing grooves.
