“…By analysis of facies, architectural elements, and Paleocurrent, Batezelli et al (2007) concluded that the deposits of the Bauru Group were formed from unidirectional and gravitational flows of high energy, associated with proximal and intermediate portions of alluvial system dominated by braided rivers (Stanistreet and McCarthy, 1993) or distributive fluvial systems (Hartley et al, 2010) arising from the Alto Paranaíba Uplift and the Alkaline Province of Goiás (Figure 1). …”

“…De spite the pres ence of sim plis tic clas si fi ca tions of flu vial distributary sys tems (e.g., Stanistreet and Mc Car thy, 1993), it is widely ac cepted that depositional pro cesses may vary sig nif icantly across FDS (Nichols and Fisher, 2007).

M., Kováè, M., Hók, J., Šujan, M., Braucher, R., Rybár, S., de Leeuw, A., 2017. Late Mio cene flu vial distributary system in the north ern Dan ube Ba sin (Pannonian Ba sin Sys tem): depositional pro cesses, strati graphic ar chi tec ture and con trolling fac tors of the Piešïany Mem ber (Volkovce For ma tion). Geo log i cal Quar terly, 61 (3): 521-548, doi: 10.7306/gq.1360Aim of the study was to in ves ti gate the de tailed strati graphic ar chi tec ture of the al lu vial Volkovce For ma tion, which was de pos ited in the north ern Dan ube Ba sin dur ing the in ter val be tween 10 and 6 Ma. Two type lo cal ity ex po sures were sub ject to fa cies anal y sis and in ter pre ta tion of depositional pro cesses and >500 bore holes served for cor re la tion of spa tial vari abil ity in the char ac ter of the for ma tion. The study was fo cused on the north ern Blatné and west ern Rišòovce de pres sions, which are partly sep a rated by the Považský Inovec Moun tains horst. It was re vealed, that a mostly grav elly flu vial distributary system of the Piešïany Mem ber was de pos ited in the north ern Blatné de pres sion, partly con fined by the ex posed horst and by in cised palaeotopography. The se quence is com posed of amal gam ated braided river chan nel bod ies with no overbank strata, in re sponse to high sed i ment sup ply and low ac com mo da tion. The palaeo-stream then crossed the horst in its southern part to wards the Rišòovce de pres sion, where there was four times more ac com mo da tion. The sub merged horst acted as a bound ary, where the depositional pro cesses changed to a me an der ing river and sig nif i cant overbank de pos its started to be pre served. Only small streams were pres ent in the north ern Rišòovce de pres sion, which led to very low sed i ment sup ply com pared to the high ac com mo da tion there. The depositional sys tem was af fected mainly by the in cised palaeotopography, by the lo ca tion of sed i ment in put to gether with spa tial dif fer ences in ac com mo da tion rate caused by the ac tiv ity of the Ripòany Fault on the south east ern side of the Považský Inovec Mts.

“…There are significant differences in the definition of alluvial fan, especially concerning participation of water flow processes in this depositional environment (Stanistreet and McCarthy, 1993;Blair and McPherson, 1994;Miall, 1996).

The deposits of the Upper Carboniferous to Lower Permian Zöbing Formation in Lower Austria have been studied by a wide range of sedimentological methods in several limited outcrops. Four facies associations were identified: (a) non-channelized finegrained deposits; (b) channelized sandstones, (c) non-channelized conglomerates, and (d) channelized conglomerates. Non-channelized fine-grained sediments are interpreted as deposits in shallow, semi-permanent pools on floodplains. Channelized sandstones are associated with fluvial processes and mostly represent crevasse channels cut into the floodplains. Channelized conglomerates originated from coarse-grained confined and hyperconcentrated flows. Non-channelized conglomerates are interpreted as sediments of alluvial fan and alluvial plain systems. A terminal fluvial system developed under a semi-arid to arid climatic regime is supposed to be the depositional environment of the Zöbing Formation.The detritus was mostly derived from primary sources formed by crystalline rocks. The proportion of metamorphites (particularly metapelitic rocks, such as mica schists, paragneisses, felsitic granulites) was predominant along with acidic magmatic and volcanic rocks. The source area predominantly can be located in the Moldanubian unit. Rapid physical erosion, redeposition and subordinately also chemical weathering are all supposed in the source area. The general provenance evolution of the entire Zöbing Formation shows local/adjacent sources in the basal parts whereas a wider provenance and variations in the primary and recycled detritus are assumed for the younger parts of the succession.________________________________________________________
