GRES A VOLTZIA-UPPER BUNTSANDSTEIN
GRES A VOLTZIA (Coniferous);U-BUNT 40X (Arenitic K-feldpat-musco sand)
Grès A Voltzia,Lower series in the Quarry block_slighty micaceous (musco.) ; Would have been good reservoir but no closure!
GRES DE ANWEILER: Upper Permian but However do classified in Lower BUNTSANDSTEIN (Triasic.lithotypal) as paleocurrent observed twrds endoreic German Bassin
GRES RHETIEN:Very clean , moderatly rounded mm quartz: Source probable: Saxonian (by palynofacies)?!
GRES RHETIEN: mm quartz with slhight K Feld rare muscov.: interpretated with lat eq. as OFFSHORE TIDAL BARS
EOLIAN ATTRITION: A DREIKANTER PEEBLE
DREIKANTER PEEBLE (5 cm) trated by PHOTOSHOP CS filters Observe equant isocelous sides
Lower side from Dreikanter peeble: this side laid down on REG and were unable to creep.
Old remembering in Vosgien SKY
Antilope aux sabres isolée.
DAY 1 stop 1-1 HAUT BARR
TAULAR BEDSETS with PLANAR X STRATA;Lateral pinch but smooth ; Grès Vosgien BUNTSANDSTEIN
Major errosinal 2 order ; Tabular -BEDSETS with planr-tengential X strata FLUVIAL DEPOSITED MEGADUNES in coarses sand with peebles
Whole are reworked dissoluted tools or concretions (carbonates) BUNTSANDSTEIN
Errosional X cross bed sets (2nd order boundaries) underlain by planar x strata of FLUVIATILE DUNES
Sequence of overfilling braided deposits channels ; Observe different orientation from X strata; FLUVIAL HYDRAULIQUE DUNES
BUNT SANDTEIN: ARKOSIK_ARENACEOUS & LITHIC sands with peeble: Crude normal grading
Sequences of X beded FLUVIAL SAND : Observe fining upwards and plain bed patterns (form below to up)
Crude strata in peeblely braided strem and due to change in grain size upper flow regime plain bed (interbeded sheet of coarse / ripples) :BUNTSANSTEIN
Stop 1.1: BUNTSANDSTEIN transtion from Grès Vosgien (Fluvial planar-curvedwedge X strata) to incoming Conglomerat principal
Conformably -slight errosive :conglomerat Principal overlying Fluvial Hydraulique dunes
Tabular-Planar X strata:Observe a 60 degree shift in dunes still in FLUVIAL one way currentdirected to German Bassin
in Planar X Strata with tengential toe within a Bed obesrve normal grading from below to top; waning stage of Dune construction for a foreset!FLUVIAL BUNTSANDSTEIN
FIRST EVIDENCE OF SOIL DEVELOPMENT IN VOSGIEN TRIASSIC SERIE; interpreted as starve of coarse sediment input and time-lag (obesrve redox-boundaries)
Chateau du HAUT BARR constructed in GRES VOSGIEN AND CONGLOM PRINCIPAL
Platty shaly clast already indurated at time of winnowing (Top grès Vosgien, BUNTSANDSTEIN) stop 1.1
Tabular bed set with Planar to tengential X strata (2D to 3D view) of Fluviatil Megadunes - Grès Vosgiens
Errsional scour from incoming dunes : obesrve plain bed (planar) due to decrease in grain size (Froude Nr>1)
A side view outcrop: for Fluvial and plaeocurrent a 3 d reconstruction is mandatory
outcrop for a 3D view : the other side
The Others side: a lot more of 3D sedimentary figures ; However still 2 D dominated: BRAIDED FLUVIAL BUNDSANDSTEIN
Above plain-parralel lamination: Dissocluted and brecciated mud clasts layering: A major surface7events happened at that particular time
fin stop 1.1 /1jour: LOOK LIKE SIGMOIDAL IT ISN't It is a 3d view from FLUVIAL DEPOSITED beds and empiled dunes.
Stp 1.2: GRES A VOLTZIA (coniferous debris) Micaceous sandstones: Could have been an excellent reservoir but no closure
Lunates slightly greenich ripples (finer chloritirezed sands) near emersions
VOLTZIA: Coniferous trees debris: No meaning with cold wether as present model
In Whitish:Eolian Grainfall deposits-observe that grainfall lie conformably with constant thickness in // lamination
Eolian deposits: probably sandsheet Whithis laminae interpreted as grain fall
Redish layer:small ripples are seen: Change in color interpreted as different in grain size as reduced coating stay on finely laminae (grainfall)
