“…Furthermore, the FO of Rucinolithus irregularis occurs be-fore Reversed-Polarity Chron MO, as was demonstrated for Pacific DSDP sites by Tarduno et al (1989). In contrast, Coccioni et al (1992) correlate the Hedbergella similis Zone with Chron M2, the Globigerinelloid.es duboisi Zone with Chron Ml, and place the FO of G. blowi in the late Barremian before the FO of Chiastozygus litterarius that continues to mark the Barremian/Aptian boundary based on a study of the Gorgo Cerbara section in Italy. Importantly, their study shows that a major part of the G. blowi Zone remains in the Aptian and continues to include Chron MO.…”

“…Little information is given as to the reasons for revising the microfossil biostratigraphy (see discussion in Tarduno et al, 1991). In fact, revision of the Barremian to early Aptian planktonic foraminiferal datums is required based on new data from Leckie and Bralower (1991) and Coccioni et al (1992). Leckie and Bralower (1991), in a study of Atlantic DSDP and ODP sites, indicate that the FO of Globigerinelloides is in the early Barremian, whereas the FO of Rucinolithus irregularis still marks the Barremian/Aptian boundary and the FO of Globigerinelloides blowi remains in the early Aptian.…”

Cretaceous planktonic foraminifers from Ocean Drilling Program (ODP) Leg 130 consist of two age groups: one dominantly Aptian in age and the other dominantly Maastrichtian. The oldest dated sediments from Ontong Java Plateau occur at ODP Site 807 and are assigned to the early Aptian Globigerinelloides blowi Zone. The assemblage correlates closely with Aptian foraminifers from Deep Sea Drilling Project (DSDP) Site 289 and a younger Aptian assemblage from DSDP Site 288 where drilling ended before reaching basement. Planktonic foraminifers from ODP Site 803 suggest a late Aptian to early Albian age and are overlain by radiolarians of late Albian age. These ages are in conflict with a radiometric age of about 90 Ma for basement at the site. The dominantly Maastrichtian group occurs at Site 807 and consists of poorly preserved, mostly small-sized specimens that range in age from perhaps the latest Campanian to the Cretaceous/Tertiary boundary. Age assignments are made difficult by pervasive dissolution and resedimentation that extends into the Paleogene.Deposition of the Aptian limestone at Site 807 took place at lower bathyal depths beneath the foraminiferal lysocline but above the calcite compensation depth (CCD). Deposition then continued beneath the CCD until the late Campanian or Maastrichtian when carbonate sedimentation resumed. Within the Maastrichtian, deposition again took place at lower bathyal depths at or above the rapidly dropping CCD until the Cretaceous/Tertiary boundary when the CCD apparently rose. Small planktonic foraminifers accumulated in winnowed and redeposited fine-grained sediments whereas larger planktonic foraminifers were deposited largely in mass-flow deposits that increase in number upsection through the Maastrichtian. The increased pulses of larger planktonic foraminifers followed by the abrupt occurrence of laminated sediments, an abundance of small, globular planktonic foraminifers, and an increase in radiolarians in the latest Maastrichtian likely were the result of northward plate motion into more productive waters and different current systems. At Site 803, deposition beneath the CCD continued from the earliest sediments above the basalt until the Eocene. Carbonate sedimentation during the late Albian to early Santonian, however, is recorded atop the plateau at Site 288.The extensive hiatuses in the Cretaceous sequence from the Ontong Java Plateau correlate in part with times of widespread hiatuses in the Pacific Basin. Evidence of pervasive mechanical erosion during the Cenomanian to Santonian and the Campanian to Maastrichtian on the top of the plateau perhaps were caused by the longitudinal position of the plateau relative to western boundary currents and eddy effects above the plateau.

“…L. hauffii is a marker of meso-eutrophic conditions (Pittet and Mattioli, 2002) and can be abundant in proximal eutrophic environments (Mattioli, 2006). Small coccoliths such as Biscutum spp., Discorhabdus spp., D. lehmannii, Z. erectus are markers of high surfacewater fertility for the Jurassic and Cretaceous (Roth, 1981;Roth and Bowdler, 1981;Roth and Krumbach, 1986;Premoli Silva et al, 1989;Erba, 1992;Coccioni et al, 1992;Williams and Bralower, 1995;Mattioli and Pittet, 2004), but were probably not competitive with respect to the dominant smaller-sized W. britannica in unstable and eutrophic surface waters for the Middle and Late Jurassic (Giraud, 2009;Giraud et al, 2009). Amongst the large-sized Watznaueria, W. manivitiae is indicative of oligotrophic conditions (Pittet and Mattioli, 2002); W. manivitiae/britannica could have a preference for proximal environments and/or high productivity in surface waters .…”

The middle Oxfordian warming climate and sea-level rise initiated the development of vast carbonate platforms in some western European basins. At the same time, however, siliciclastics and siliceous sponges dominated certain marginal areas of the Iberian ramp. There, siliciclastic input was particularly prominent during the latest Oxfordian and may have been related to a global sea-level fall, synsedimentary tectonic activity, or humid climatic conditions in the hinterland. Field analyses and computer modeling have been previously used to determine the factors that controlled sedimentation. However, it is still unclear if the specific conditions that prevailed during the latest Oxfordian were due to eustasy, tectonics or climate, and when precisely they occurred. Here, we document major changes in sedimentological, micropalaeontological, and mineralogical records on the Iberian ramp during this interval. Detailed sedimentary facies and palynofacies analyses combined with sequence-stratigraphic and cyclostratigraphic analyses of the Ricla Barranco section enable the establishment of a high-resolution time frame. Based on the quartz and mica percentage fluctuations, one large-and seven small-scale sequences are defined. The large-scale sequence boundaries correlate with third-order sequence boundaries Ox8 and Kim1 defined by Hardenbol et al. (1998). The large-scale maximum-flooding surface corresponds to the base of the most calcareous interval and to the maximum abundance of marine phytoplankton and opaque, equidimensional phytoclasts. The small-scale sequences correspond to the 100-kyr orbital eccentricity cycle. Calcareous nannofossils and clay minerals were used as palaeoclimatic proxies. Nannofossil abundances and fluxes are lower in the upper part than in the lower part of the interval studied, suggesting a decrease in sea-surface trophic conditions, also shown by an increase in the relative abundance of oligotrophic taxa. This upper part is also characterised by an increase in smectite, which coincides with the base of the large-scale highstand deposit, and is interpreted as reflecting the establishment of dry conditions. A first increase in smectite occurs in the lower part of the succession, and coincides with high percentages of quartz and mica. This latter mineralogical assemblage is interpreted as recording the onset of the Late Jurassic to Early Cretaceous rifting stage, which occurred just before the Planula-Galar ammonite Subzone transition. The present study points out a return toward optimum conditions for carbonate sedimentation only 300 kyr after the prominent increase in siliciclastic input due to tectonic activity. The recovery of carbonate production was accompanied by a global sea-level rise and by decreasing rainfall on nearby land.

Age and correlation of the Calera Limestone in the Permanente terrane of northern California

Planktonic foraminifers indicate that outcrops of Calera Limestone from the Permanente terrane in the Franciscan Complex of northern California range in age from possibly as old as Barremian to late Turonian. Underlying black limestone, which is devoid of planktonic foraminifers, presumably is Barremian in age or older. The top of the sequence exposed in major quarries is always faulted. Improved biostratigraphic resolution shows two patterns of missing time intervals. The primary pattern, which is found at all localities and involves missing planktonic foraminiferal zones in the late Aptian to early Albian and the late Albian, is linked to paleoceanographic changes in the Cretaceous Pacific Ocean. The secondary pattern, which is found at the scattered outcrops outside the major quarries and involves missing zones in the Albian and Cenomanian, suggests the results of a common tectonic history related to the accretion of a large seamount.
