( 英 文 ). Harzhauser M; PillerW E. Stratigraphy, 2004, 1(1): 65-86The Vienna Basin and the Styrian Basin havebeen cornerstones for the definition and descriptionof the Central EuropeanSarmatian Stage.New inter- and intrabasin correlations of welllogsand surface outcrops reveal a rather uniformdevelopment of depositional systems in all consideredbasins, which excludes local autocyclicprocesses as the sole trigger. The lithostratigraphyofthese basins is critically summarized andthe Wolfsthal Member is introduced as a newlithostratigraphic unit.The more than 1000-mthickSarmatian basin-fill is recorded in geophysicallogs by a characteristic succession ofserrated funneltobell-shaped curves separated byshale-line intervals. The correlative floodings arewell preserved in marginal settings and accessiblein surface outcrops. Slight falls of the relativesea-level are also reflected in the littoralzone by erosive surfaces, caliche formation andprogradation of fluvial facies. The stratigraphicposition and duration of the Sarmatian suggests arelation to the 3rd order cycle TB. 2.6.Internally,two 4th order cycles are depicted. An exact correlationwith Mediterranean standard stages andthe “Haq-cycles” is difficult due to the endemicmarine fauna thatflourished in the nearly landlockedParatethys Sea during the Sarmatian. Thisobstacle may be overcome by a first cautiouscalibrationof the sedimentary sequence with astronomicaltarget curves. Hence, the 400-Ka eccentricitycomponent might have triggered the4th ordercycles, with the maximum floodingsurfaces coinciding with the maxima of thatband. An overall trend from a pelitic-siliciclasticLower Sarmatian 4th order cycle towards anoolitic Upper Sarmatian 4th order cycle could beforced by the inflection of the 2.35-Macomponent. The tentative calibration requiresa new positioning of the Badenian/Sarmatianboundary close to 12.7 Ma, which would fitexcellentlyto the glacio-eustatic isotope eventMSI-3.The coincidence of the final retreat of thesea from the Molasse Basin with a major phaseof progradation of alluvial fans into theStyrianand the Vienna Basins suggests a pulse of upliftin the eastern Alpine region at 12.1-12.3 Ma.2008040592修 订 的 Massignano 始 新 世 - 渐 新 世 金 钉 子 剖面 = The Massignano Eocene-Oligocene goldenspike section revisited. ( 英 文 ). Van Mourik C A;Brinkhuis H. Stratigraphy, 2005, 2(1): 13-30In common practice, the Eocene/Oligocene(E/O) boundary is linked to the Oi-1 18O benthicisotope event, reflecting the oldest phase ofmajor Antarctic glaciation, calibrated againstmagnetosubchron C13n. Yet, the IUGS-ratified,current E/O GlobalStratigraphic Section andPoint (GSSP) at the pelagic Massignano quarrysection, central Italy, occurs within the oldermagnetosubchronC13r. To extend the Massignanorecord further into the early Oligocene, toinclude the critical C13n episode missing in thesurfacesection, a core was drilled in the directvicinity of the quarry section. First correlationsbetween the core and the quarry sectionhaverecently been proposed. In this paper, we usehigh-resolution organic-walled dinoflagellatecyst (dinocyst) analysis to significantlyimprovecorrelation between the two sections. In addition,we build on earlier studies, and demonstrate thatthe current E/O GSSP criterion, which is basedon the local extinctionof the tropical planktonicforaminifera genus Hantkenina represents anisolated event that is not suitable for global correlation.Instead,we argue that selection of theOi-1 event be the main criterion for the determinatingthe E/O boundary, and that this providesamuch better basis for global correlation, Moreover,the Oi-1 is also related to the TA4.3/4.4third order sequence boundary andthe last occurrenceof the dinocyst Areosphaeridium diktyoplokum.Selection of this slightly youngercriterion would place the upperboundary of theclassic Priabonian Stage back in the latest Eocene,and the base of the Rupelian Stage in theearliest Oligocene. Since the proposed correlativeOi-1 event level is not represented in thesurface (quarry) section, but only resides in thecored section atMassignano, a new GSSP siteshould be selected, for example in one of theother central Italian sections that does span C13n.2008040593Massignano 始 新 世 - 渐 新 世 金 钉 子 剖 面 的 修订 = The Massignano Eocene-Oligocene goldenspike section revisited.
