“…These flow regime transformations can be attributed to changes in the hydraulic conditions in relation to surface and/or fluidization transformations (cf. Fisher, 1983) due to the ingestion of water or upward movement of fluids within the flow (Fisher, 1983). Their massive nature is similar to described cohesive debris flows (Lowe, 1982), whereby such flows are capable of transporting large blocks in a matrix of lapilli-and ashsized fragments (Prothero and Schwab, 1996).…”

“…The con se quence is flow deconcentration caused by assim i la tion of am bi ent flu ids, aqua plan ing and inter gra nu lar flow up wards. In such cases, what may oc cur is not only the evolv ing of slides/slumps into de bris flows but also trans for ma tions directly into tur bid ity cur rents or of de bris flows into tur bid ity currents (see Unrug, 1963;Fisher, 1983;Shanmugam, 2006;Fe lix et al, 2009;Mulder, 2011). Pres er va tion of sub ma rine sandygrav elly slumps as synsedimentary folds, rup tured to dif fer ent de grees, among other non-de formed de pos its, is usu ally limited.…”

“…Typ i cally, slumps are not "frozen" but evolve into sandygrav elly de bris flows, in which al most com plete decoherence and ho mog e niz ing of the trans ported non-co he sive gran u lar mass is ob served. A low mud ma trix con tent in "clean" sandygrav elly de bris flows can be ex plained, e.g., by elutriation, i.e., the wash ing away of clay and silt-sized par ti cles dur ing flow trans for ma tion into a tur bid ity cur rent (see Fisher, 1983).…”

“…Clastic ma te rial may be quickly de pos ited by fric tional freez ing in the case of a non-cohe sive gran u lar mass. In the case of sed i ments rich in mud, their re de pos ited mass, par tic u larly in muddy flows or muddy de bris flows, may be hin dered by co he sive strength or, due to di lu tion, incrementally trans formed into tur bid ity cur rent to vary ing de grees dur ing fur ther move ment (see Unrug, 1963;Fisher, 1983;Shanmugam, 2006Shanmugam, , 2012Fe lix et al, 2009;Haughton et al, 2009;Mulder, 2011;Talling et al, 2012).

The study fo cuses on Up per Cre ta ceous-Paleocene de pos its from the Beskid Śląski moun tain range in south ern Po land con sti tut ing the Istebna Beds. The Istebna Beds, also re ferred to as the Istebna For ma tion, are part of the Silesian tec tonic unit, which forms the Outer Carpathian fold-and-thrust belt (part of the Al pine-Carpathian sys tem). The re sults of qual i ta tive and quan ti ta tive lithological-sedimentological stud ies were the ba sis for the in ter pre ta tion of lithofacies types, sed i men tary pro cesses and palaeoenvironment as well as for the re con struc tion of the ar chi tec ture of the depositional sys tem. The anal ysis con ducted on the ba sis of field de scrip tion of the de pos its shows the prev a lence (nearly 70%) of siliciclastic strata rep resent ing a sand stone-con glom er ate as so ci a tion (S-C), which is the main sub ject of this work. The S-C lithofacies: sand stones, grav elly sand stones, sandy con glom er ates and con glom er ates con sti tute the de pos its formed mostly by mass grav ity-flows such as sandy-to-grav elly de bris flows. The dis tri bu tion of the coarse-clastic ma te rial in di cates a sed i ment supply from south erly di rec tions and im plies the pres ence of an ac tive source area in the rear part of the Silesian Ba sin. A succes sion of the sand stone-to-con glom er ate de pos its with the sec ond ary par tic i pa tion of other lithofacies, with a thick ness of ap prox i mately two thou sand metres, in di cates tem po rary in creased di a strophic ac tiv ity in the Silesian Ridge (source area) and the in tense de nu da tion of this area. The up lift of the alimentation area and its de struc tion co in cid ing with en forced rel ative re gres sion and the un cov er ing of the prox i mal depositional zone of the ba sin led to resedimentation of the older intrabasinal ma te rial and re peated mass de po si tion to gether with de liv ery of extraclasts of pre-ex ist ing rocks and min er als. The lithofacies de vel op ment of the sand stone-to-con glom er ate debrites and the re lated sed i men tary palaeotransport di rections sug gest an ac cu mu la tion do main in the form of a lin ear apron depositional sys tem de vel oped in a deep-wa ter set ting. Ex per i men tal mod el ling of sub aque ous sandy flows has con trib uted to a better un der stand ing of the com plex gen e sis of deep-wa ter sed i ment grav ity flows de vel op ing in depositional sys tems rich in sand ma te rial.
