“…The Preservation Inlet incursion coincides with records of MWP1b in Canada (Dallimore et al, 2008;Fig. 8), (Hearty et al, 2010), Japan (Tanabe et al, 2009) and Australia (Andres et al, 2003) (see also Table 1). Antarctic evidence of MWP1b dated around 11.3 ka (Weber et al, 2014) correlates closely to the Preservation Inlet record.…”

a b s t r a c tThe modern fjords of southwest New Zealand were previously stranded lakes isolated from the Tasman Sea by bedrock and moraine sills following the retreat of glaciers at the Last Glacial Maximum. The isolated lake basins were subsequently inundated with sea water when sea-level rise overtopped the sills. A record of the lacustrineto-marine environmental transition is preserved in the fjord basin sediments and is identified in two New Zealand fjords with high-resolution seismic data and paleoenvironmental analysis of sediment cores. Seismic data are used to constrain the maximum sill depth and microfossil assemblages are used to track the lacustrine-to-marine transition. Chronology is based on fourteen radiocarbon ages. A relative sea-level curve for Fiordland, New Zealand is constructed based on sill depths and age constraints on the marine incursion. The sea-level curve allows insights into estimated uplift rates for Fiordland during the Holocene. From a lowstand of at least 107 mbsl 14,750 yr ago, these data reveal a stepwise transgression. Meltwater Pulse 1b is identified between 12,400 and 11,400 yr ago, with a second acceleration in sea-level rise observed 9700 yr ago. This record contributes a new sea-level curve for a mid-latitude (45°S) Southern Hemisphere location as well as new evidence for Meltwater Pulse 1b.

“…Coated‐grain grainstone, along with lithoclasts of ooid grainstone, is interpreted to form in shallow‐water and agitated‐water environments, probably above the fair‐weather wave base (Harris, ; Halley et al ., ; Gawthorpe & Gutteridge, ; Hearty et al ., ). Colonies of in situ Chaetetes are also indicative of shallow‐water environments (Connolly et al ., ; West & Kershaw, ; Merino‐Tomé et al ., ).…”

Facies, geometry and growth phases of the Valdorria carbonate platform (Pennsylvanian, northern Spain)

The 14 km wide Valdorria outcrop (Pennsylvanian, Northern Spain) is one of the few examples of entirely exposed flat-topped and high relief carbonate platforms reported in the fossil rock record. Laterally and vertically traceable stratal patterns expose three phases of growth. Phase I is a 430 m thick platform to slope succession that prograded over 6 km, and is dated as Early Bashkirian (Akavasian–Askynbashian). Phase II aggraded and prograded, exhibiting 180 m thickness of cyclical platform top deposits, dated as Late Bashkirian (Asatauian). Phase III is a mound-shape structure that developed over the platform top of Phase II as a new phase of platform nucleation. It is 535 m thick and 2 km wide, and dated as Late Bashkirian (Asatauian–Transition interval). The observed changes of growth styles during platform evolution, from a prograding to an aggrading–prograding system, and a rapid aggradational phase, are inferred to be controlled by flexural subsidence in the active Cantabrian foreland basin, at the Variscan orogenic front. The metre-scale shallowing-upward cycles of the platform top are most probably due to glacioeustasy, as evidenced by well-recorded subaerial exposure surfaces superimposed on subtidal deposits, and by a stratal pattern recurrent in a short interval of about 160 Kyr. Observations of outcropping Bashkirian cyclothems in an isolated carbonate system, devoid of siliciclastic input, are relevant for a better understanding of the impact of high-frequency sea-level fluctuations on the carbonate factory. Moreover, progradation of the platform margin during Phase I reaches a rate of 2500 m/Myr, and 1810 m/Myr during Phase II; rates that are high when compared to other Pennsylvanian examples. The aggradation rate of 447 m/Myr calculated for Late Bashkirian–Transition interval (Phases I and II; uncorrected for compaction, missing beats and erosion) is uncommonly high in comparison to coeval Pennsylvanian examples. The platform exhibits a self-nourishing prograding microbial boundstone-dominated slope. Thus, the slope shedding model applies well to Valdorria. However, Phase II recorded eustatic variations able to inhibit the slope microbial boundstone factory during low sea-level stands; this is marked by common slope red-stained breccias synchronous to platform top subaerial exposure phases. Contrarily, periods of relative high sea-level and rapid subsidence in Phase III registered a greater development of cemented microbial boundstone. These observed, partly opposing relationships of sea-level stands, shedding modes and slope architecture provide an improvement of the currently used slope shedding model. The overall architecture of the Valdorria outcrop compares well with that of other contemporaneous platforms, such as Sierra del Cuera and Bolshoi Karatau. Valdorria shares the high-relief and flat-topped, steep slopes, cyclothemic patterns and occurrence of karst features with the Pricaspian Basin platforms (Tengiz, Karachaganak and Kashagan), with minor variations in facies distribution of the...
