Combined analyses of cores, borehole geophysical logs, and cyclostratigraphy produced a new conceptual hydrogeologic framework for the triple-porosity (matrix, touching-vug, and conduit porosity) karst limestone of the Biscayne aquifer in a 0.65 km 2 study area, SE Florida. Vertical lithofacies successions, which have recurrent stacking patterns, fit within high-frequency cycles. We define three ideal high-frequency cycles as: (1) upward-shallowing subtidal cycles, (2) upward-shallowing paralic cycles, and (3) aggradational subtidal cycles. Digital optical borehole images, tracers, and flow meters indicate that there is a predictable vertical pattern of porosity and permeability within the three ideal cycles, because the distribution of porosity and permeability is related to lithofacies. Stratiform zones of high permeability commonly occur just above flooding surfaces in the lower part of upward-shallowing subtidal and paralic cycles, forming preferential groundwater flow zones. Aggradational subtidal cycles are either mostly high-permeability zones or leaky, low-permeability units. In the study area, groundwater flow within stratiform high-permeability zones is through a secondary pore system of touching-vug porosity principally related to molds of burrows and pelecypods and to interburrow vugs. Movement of a dye-tracer pulse observed using a borehole fluid-temperature tool during a conservative tracer test indicates heterogeneous permeability. Advective movement of the tracer appears to be most concentrated within a thin stratiform flow zone contained within the lower part of a high-frequency cycle, indicating a distinctly high relative permeability for this zone. Borehole flow-meter measurements corroborate the relatively high permeability of the flow zone. Identification and mapping of such high-permeability flow zones is crucial to conceptualization of karst groundwater flow within a cyclostratigraphic framework. Many karst aquifers are included in cyclic platform carbonates. Clearly, a cyclostratigraphic approach that translates carbonate aquifer heterogeneity into a consistent framework of correlative units will improve simulation of karst groundwater flow.

Late Cretaceous calcareous nannoplankton zonation of Jamaica
Six biozones can be recognized in the Turonian to the Lower Maastrichtian of Jamaica. In descending stratigraphic order, the boundaries separating these six zones are coincident with the last occurrence of Calculites obscurus, Quadrum trifidum, Eiffellithus eximius, Eiffellithus gorkae, Lithastrinus septenarius, and Lithastrinus moratus, respectively. This scheme provides a consistent zonation that has been recognized in three wells and one surface section. The ages of the last occurrences of the zonal markers, as well as of the last and first occurrences of other relevant taxa, have been derived from a comparison of several syntheses of Cretaceous nannofossil biostratigraphy. Additional Jamaican sections and spot samples bearing Late Cretaceous nannoplankton are correlated to this regional zonation. Changes in nannofossil abundance in the four major stratigraphic sections indicate environmental shifts and intervals of nondeposition on Jamaica during the Late Cretaceous. One Eiffellithus species that apparently has not been published previously is described in open nomenclature.
Campanian calcareous nannofossils in the Sunderland Inlier, western Jamaica
Calcareous nannofossil assemblages in Campanian rocks in the Sunderland Inlier, western Jamaica, are documented and assigned to Sissingh’s (1977, emended 1978) zones 19, 21, and 22, his zone 20 being missing due either to a local fault or to an unconformity. Of the 107 calcareous nannofossil species identified, five new combinations are proposed: Chiastozygus dennisonii, n. comb., Cretarhabdus sinuosus, n. comb., Tranolithus bitraversus, n. comb., Uniplanarius sissinghii, n. comb., and Zygodiscus pontilithus, n. comb.
Cretaceous orbitoid larger foraminifera of the families Pseudorbitoididae, Orbitoididae, and Orbitocyclinidae are known from the Green Island and Grange inliers (western Jamaica), from the Sunderland and Central inliers (west-central Jamaica), and from the Blue Mountain Inlier (eastern Jamaica). They occur in prominent limestone units that are regarded as ranging in age from Campanian to Early Maastrichtian on the basis of nannofossils and accompanying rudist assemblages. Cretaceous pseudorbitoid, orbitoid, and orbitocyclinid foraminifera are useful in interpreting fluctuations of the depositional environment and for time-stratigraphic correlation of Late Cretaceous limestones across Jamaica.
Ostracode biostratigraphy of the Titanosarcolites-bearing limestones and related sequences of Jamaica
The Cretaceous limestone and limestone rubble beds of Jamaica that contain the rudist Titanosarcolites with associated macroinvertebrates, and the shales between them, contain a diverse ostracode assemblage. The same is true of the shales associated with the so-called oyster limestones. Samples from the Central, Maldon, Marchmont, and Jerusalem Mountain inliers have yielded more than 123 species, only two of which can be confidently assigned to known species. Many of these taxa are rare or are still under study, but 38 common forms allow the division of the studied interval into three very distinct zones, the oldest of which can be divided into three subzones. The Titanosarcolites and associated shales of the Central, Maldon, and Marchmont inliers can all be placed in the oldest zone delineated. Using the subzones of this zone, lithic units can be correlated from inlier to inlier. The small Jerusalem Mountain Inlier has two different ostracode assemblages. The Titanosarcolites beds of this inlier are placed in one of these, and the younger oyster limestone beds and associated shales fall in the other. The presence of the genera Schizoptocythere, Buntonia, and Ovocytheridea indicates a tropical Tethyan affinity for the Jamaican ostracode fauna. It is distinctly unlike the richly fossiliferous deposits of the North American Coastal Plain. A review of the chronostratigraphic position of the Campanian-Maastrichtian boundary and an alternate interpretation of recently published calcareous nannofossil data for the Jamaica deposits support the conclusion of macrofossil workers that the Titanosarcolites beds are Maastrichtian and not partly Campanian in age.
Upper Cretaceous ammonites from Jamaica and their stratigraphic and paleogeographic implications
Nine ammonite species from the Upper Cretaceous of Jamaica are revised and described briefly, including one new species, Pachydiscus (P.) jamaicensis n., of Lower Campanian age. The Cretaceous ammonite fauna is classified into four different levels: Level 1 with Peroniceras cf. moureti Grossouvre, Lower Coniacian; Level 2 with Nowakites lemarchandi (Grossouvre), late Santonian; Level 3 with Pachydiscus (P.) koeneni Grossouvre and Glyptoxoceras retrorsum (Schlueter), early Campanian; and Level 4 with Pachydiscus (P.) oldhami (Sharpe), late Campanian. No older pelagic facies have been recognized. These ammonite levels correlate perfectly with inoceramid "zones" proposed by Kauffman (1966). The biostratigraphy established in this paper facilitates correlation between the different sedimentary facies of the scattered and isolated Upper Cretaceous outcrops in Jamaica. Paleobiogeographic relations can be established with Europe (Level 4), southern India (Level 3), Madagascar (Level 2), and Japan (Level 1).
Twelve species of fossil echinoid have been recognized from the Jamaican Cretaceous. Only two taxa, the cidaroid Phyllacanthus leoni (Lambert and Sánchez Roig) and the arbacioid Goniopygus supremus Hawkins, are known from the Cretaceous of both Jamaica and Cuba. They are also the two most common echinoids in the Jamaican Cretaceous. Two other cidaroid species, including Temnocidaris? (Stereocidaris) sp., have been identified from disarticulated radioles only. Two other species of regular echinoid, the acrosaleniid Heterosalenia occidentalis Hawkins and the temnopleuroid Scoliechinus axiologus Arnold and Clark, have been described. The late Cretaceous age of S. axiologus is uncertain. Irregular echinoids are less common. Only Hemiaster! sp. (or spp.) is abundant, although it is usually poorly preserved. Other irregular echinoid species include the unique holectypoid Metholectypus trechmanni Hawkins, the cassiduloid Pygopistes? rudistarum (Hawkins), and a cassiduloid sp. indet. Two taxa, Orthopsis sp. and a nucleolitid sp. nov., are awaiting description. Most of these taxa are of Campanian and/or Maastrichtian age. Jamaican Cretaceous echinoids are best known from the Marchmont and Central inliers.
Thirteen species of fossil articulate brachiopod are documented from the Cretaceous and Cenozoic rocks of Jamaica. Dyscritothyris sp. cf. D. cubensis and Terebratulina? sp. are described from the upper Cretaceous; the Cenozoic fauna comprises the rhynchonellide Probolarina? sp., the thecideid Lacazella sp. cf. L. caribbeanensis and the terebratulides Gryphus ? sp., Tichosina sp., Argyrotheca sp. cf. A. barrettiana, A. sp. cf. A. magnicostata, A. sp. 1 and A. sp. 2, Terebratulina sp. cf. T. palmeri, Terebratulina sp., and Hercothyris sp. cf. H. semiradiata.
The Cretaceous of Jamaica has so far yielded only eleven specimens of decapods belonging to four genera; these are all recorded. One of them, Carcineretes woolacotti, is considered to be a back burrower and not a swimmer as previously thought. The flattened fifth leg of burrowers such as C. woolacotti is considered to be a preadaptation to swimming as seen in the more-advanced Portunoidea. All previously published Cenozoic decapods and cirripedes are recorded. The decapods belong in five genera, and there are three genera of cirripedes. Fourteen decapod taxa are recorded for the first time from the Pleistocene raised-reef terrace of Rio Bueno, mostly in open nomenclature.
Nonechinoid echinoderms are poorly known from the fossil record of Jamaica and only occur as disarticulated plates. Only crinoid columnals have hitherto been reported. However, asteroid marginal ossicles and ophiuroid vertebral ossicles are also locally common. Three species of isocrinid are recognized: cf. Cenocrinus asterius (Linné) from the Lower Pleistocene, Diplocrinus sp. from the Miocene, and an isocrinid sp. indet. from the Eocene. The microcrinoid Applinocrinus cretacea (Bather) and an indeterminate comatulid are both known from the Upper Cretaceous. Asteroid marginal plates (astropectinids and/or goniasterids) have been recovered from two Maastrichtian, three Eocene, and one Oligocene localities. Ophiuroid vertebral ossicles have been recovered from a patch reef in the back-reef lagoonal facies of the Upper Pleistocene (last interglacial) Falmouth Formation.
Calcareous nannofossil stratigraphy of the Neogene formations of eastern Jamaica
While numerous studies have been devoted to the planktonic and benthic forami-nifera in the Neogene of Jamaica, little attention has been paid to the calcareous nannofossils. This contribution is thus a documentation of the calcareous nannofossils in the lower Miocene to upper Pliocene deposits of Jamaica. The Buff Bay section, the most extensive Neogene section in eastern Jamaica, is studied in great detail, and eight other sections, including the San San Bay and the Bowden type sections, are discussed as well. Current correlations between the zonal schemes established from calcareous nannofossils and planktonic foraminifera are discussed, based upon direct correlation between calcareous nannofossil and planktonic foraminiferal zones in these sections. Integration between calcareous planktonic microfossil stratigraphies, and magnetostra-tigraphy when available, leads to the delineation of regional unconformities and to the interpretation of the Neogene stratigraphic record of eastern Jamaica in terms of sequence stratigraphy. It is shown that the Buff Bay Formation, the San San Clay, and the Bowden Formation correspond to separate unconformable stratigraphic sequences. As a result, it is suggested that the San San Clay be regarded as a distinct formation rather than part of the Buff Bay or the Bowden formations as currently accepted. Several of the “holotype” and “paratype” localities that Blow (1969) designated for his Neogene planktonic foraminiferal zones (N-Zones) are located in Jamaica. Direct correlation between these and the calcareous nannofossil schemes of Martini (1971) and Okada and Bukry (1980) are established and the implications are discussed.
