Krzeszowice Graben
South Poland - Opis:
- The pa per aims at re con struct ing Pleis to cene slope pro cesses and trans for ma tion of tec tonic re lief in two sec tions across the north ern mar gin of the Krzeszowice Gra ben. The in ves ti ga tions are based on the analy sis of de pos its pres ent on the slopes of fault- line scarps. The li thol ogy and stra tigra phy of these de pos its was re con structed based on analy sis of out crops and bore holes. De tailed litho logi cal logs were pre pared, along with grain size analy ses, and de ter mi na tion of CaCO3, Fe2O3 and Corg con tents in fine- grained sedi ments. The stud ied fault- line scarps were trans formed by Pleis to cene de nu da tion. The type and in ten sity of these pro cesses were dif fer ent in the sec tions stud ied. In the Bêd kowice area, ac cu mu la tion pre vailed; the fault- line scarp be came cov - ered with sedi ments. In the Kar niowice area, in turn, peri gla cial pro cesses caused deg ra da tion of the fault- controlled slope. In the lower part of the fault- line scarp, the in ten sity of deg ra da tion pro cesses was lim ited by re peated pres ence of sedi ment cover which pre served the sub stra tum. Dif fer ences in the in ten sity and type of Pleis to cene de nu da tion can be ex plained by dif fer ent heights of fault- line scarps, con trolled by tec tonic struc ture and neo tec tonic move ments.
