2008 FIELD TRIP, PARALIC SEQUENCES
Meeting point : BOCHUM ZENTRUM RUHR BERGBAU MUSEUM
Major uncomformity: angular Coal bearing sandstones form Westphalian A overlain by Cenomanian Green sands from Essen Fmt
Bochum center park
Basal conglomerates;Essen Green sands Cenom.
Zoom: conglomerates with reworked Westpalhien coal found. Bochum center
50 m AwaySAme angular unconformity but with coarse-medium Green Sands
Major angular uncomformity with scours filled with boulders Coal and Carboniferous material reworked during Transgression
again 50 m away fine sands
Simple actual model for Green SANDS: Cliff errosion provide nearshore boulder and 50 away medium sands
Our FIELD TRIP GUYS: JORG AND MARKUS in front of Emshen Marls
Prof Mutterlose
Right Where we go...
Emsha Marls 800M thick N of Munsterland bassin:DEPOCENTER Towards SE: Thickness reduced diachronusly to 80 m
Emsha marls: obesrve bediing rythm interpreted clay LST Caco3 beds MFS and above HST here nutrient input was high
Johan and aurélie from France
Ocres sands quarry
Quarry of "Ocres" Fine sands
munsterland bassins
Basic Model for this 300M thickness clean and uniform fine sand with bioturbation and sed.figures
ophiomropha ichnogenus part of High energy unconsolidated grouns from Skolithos Ichnofacies
Possible Thalassionodes of skolithos?
Look like Eolian:Closely it isn't Marine bioturbation marine fauna & sedimentary features relevant for marine deposition systems
Typical Ophiomorpha ichno genus: Obesrve the high enery plan lamination of probably foreshore high energy facies
Just above finger:skolithos concentric ichno genus
En route to BAUMBERGER FMT
Querry: Late campanian Bio-clsatic sands cemented by calcite {M} thick block for building uses
Johan Schnyder from PARIS-Clichy
Berrisian Coal bearing overlain by fine shale and massive sandstones
Inetrpreted as Mouth bar massive structurless Massive sands Followed by slightly errosional Through cross beds above
European-Tethysian realm major unconformity reported in Egypte-Tunisia-UK-Norway-France-Spain(?) comment appreciated!
Berriasian-Early Val: European & Thethysien major angular uncomformity reported from participants
Upper Valanginien massive sandstones : Above 20 M ; Bioturbation trace...
RHIZOCORRALIUM ICHNOGENUS part of CRUZIANA ichnofacies Mid-poor consolidated sand Spreite noticeable
From above:Thalassinoides like genus trace together with rhizocorralium Sahllow marine :Between FWB and SWB
NIGHT STOP 1 night 05-sept 2008
FROM R TO L: Nodular limestones-marlstones :PLENUS MARLS Level Fine silty deposited whethered Swell like Fine black shaly marls CENOMANIEN
Above B.Shale recovery macrofaunal INOCERAMIDS sp.well developped.
inoceramus sp post recovery fauna from black shale mfs event
Theory and source from FACOIDS block: VOIGT
facoid blocks
FACOIDS (VOIGT) Block in slide masses
MEGA-SLUMP Presumably form right to left:plastic deformation is needed for overturned beds & v.High energy current just above Turbidites calci-lutite , CAMPANIAN
Mega-Slump: conspicuous overturned BEDS plastic deformation of muddy limestones and ramp thrust observed.
Calci turbidites on outer-intra shelf or shelf edge: Campanian.
Look intraclast reworked:prsumably from outer-shelf slope?
Commonly found In turbidites & associated in with NEREITES-ZOOPHYCOS ICHNOFACIES CHONDRITES ICHNO GENUS
