SOME CHARACTERISTICS OF EOCENE FLYSCH GENESIS, COMPOSITION AND WEATHERING IN CROATIAN COAST BELT
TL;DRAbstract
The most common lithotypes of the Eocene flysch in the Croatian coast belt are breccias, conglomerates, (bio)calcirudites, (bio)calcarenites, sandstones, siltstones, shales and marls. Olistolithes also can be constitutive part of Eocene flysch. On the surface they can be mapped only in wider Split area. The mechanical weathering of the flysch rock mass is dominant in regard to the chemical weathering which is almost irrelevant for practical purposes. Mechanical weathering is caused by tectonic activities, and by repeated drying and wetting. It takes place in the engineering time, and not geological, which dictates the method of excavation, protection of slopes and construction pits in flysch rock masses. The quantity of the eroded material can extend 20000 m3/km2/yr. Most subject to erosion are lithotypes which are dominantly made of clast varying in size from silt to clay. The Slani Potok catchment in the Vinodol Valley mainly consists of Eocene flysch sediments. Its feature is that i
