The lower cretaceous paraflysch of the Vardar zone: Composition and fabric

Abstract

The Lower Cretaceous paraflysch forms an outstanding, 250 km-long belt in the Vardar Zone. It is composed of a basal unit, uncomformable over Jurassic limestones and older rocks, and of two megasequences with the a clastic lower and clastic-carbonate upper member. In this study, We analyzed the orientation of the sedimentary bedding, cleavage and schistosity, fold hinges and axial surfaces and cleavage - bedding intersection lineation, were analysed. The area experienced two phases of folding, first with fold hinges oriented NNW and the second with hinges oriented WSW. The regularities of these structures and their relationships are, as shown by these investigations, only statistically to be used in practical study of fabric.Donjokredni paraflis gradi u Vardarskoj zoni veoma izrazit pojas dug 250 km. Sastoji se od bazalne jedinice diskordantne preko gornjojurskih krecnjaka i melanza, kao i dve megasekvence sa donjim klasticnim i gornjim klasticno-karbonatnim clanom. Statisticki su analizirani padovi svih slojeva, prevrnutih slojeva, klivaza i skriljavosti, osa nabora, aksijalnih povrsi nabora i preseci klivaza i slojeva. Pravilnosti ovih struktura i njihovih odnosa su, kako je pokazalo ovo istrazivanje, samo statisticki upotrebljive pri prakticnim ispitivanjima sklopa.
