Kratka vsebinaZaradi znatnih koncentracij uranove rude je Brebovniški člen najpomembnejši člen Grodenske formacije. Kamnine smo glede na zmatost, sedimentne teksture in sestavo ločili v konglomeratne, peščenjakove, muljevčeve in karbonatne faciese ter interpretirali pogoje njihovega nastanka. Iz podrobnih delnih profilov smo sestavili poenostavljeni profil celotnega Brebovniškega člena v skupni debelini skoraj 400 m. V njem smo ločili dva makrocikla. Prvi obsega spodnjo polovico Brebovniškega člena, drugi pa njegovo zgornjo polovico in približno spodnjo polovico Hobovškega člena. Makrocikla sta produkt rečnega sedimentacijskega okolja z vsemi svojimi podokolji in sta alocikličnega značaja. Alocikličnost so najverjetneje kontrolirala tektonska dogajanja v drenažnem zaledju in sedimentacijskem bazenu. Makrocikla predstavljata razvoj rečnega sistema od proksimalnih delov s prevladujočim talnim transportom prepletajočih rečnih korit in aluvialnih vršajev proti distalnejšim delom z mešanim talno-suspenzijskim transportom meandrirajočih rečnih korit.

“…Such analysis delivers important indications about the sediment origin, transportation mechanism, and depositional environments [5]. Many researchers, including [1,2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], proved that the grain-size parameters can reveal the sedimentary conditions since each environment has unique characteristics that can be distinguished from others.…”

Grain-size analysis is a significant descriptive method to determine and evaluate depositional environments and hydrodynamic conditions in addition to classifying sedimentary rocks. In this study, grain-size analysis was conducted using dry-sieving procedures on fourteen representative sandstone samples from the Wasia Formation, a thick water aquifer and a hydrocarbon reservoir. Hydrodynamic conditions and depositional environments were determined using bivariate plots, linear discriminate function (LDF), log probability, and Passega diagram. The results reveal that the lower outcrop section consists of coarse- to medium-grained sandstone with a majority being poorly sorted, while the upper section is made up of medium- to medium-well-sorted fine-grained sandstone units. The sediments have a unimodal distribution of 2∅ (all the lower section) and 3∅ (most of the upper section), while two beds have a bimodal of 2 and 3∅. The lower section has wide range skewness with mainly mesokurtic curves, while the upper section is near-symmetrical to coarse-skewed but mostly leptokurtic. Additionally, log probability plots and the Passega diagram show that the majority of the indicative sediments were transported via one to two saltation levels, while fine-grains were transported via suspension. The results of the LDF method are predominantly indicative of aeolian, marine, and fluvial environments.
