“…In analogy with the diagenetic evolution in Cenozoic shallow-water carbonates, one may suspect that these processes of aragonite solution/calcite precipitation took place under the influence of meteoric waters. In the total absence of features diagnostic for the vadose environment, such as meniscus (Dunham, 1971) or gravitational (Purser, 1969) cement, aragonite solution and calcite cementation would have taken place in a phreatic environment, and could be correlated with the early phase of seamount evolution when much of the volcanic edifice was still emergent and a fresh-water lens existed below the island. Such a situation is also suggested by reflection seismic data showing that the drilling site is situated along the margin of the seamount, in a younger tectonic depression (Greene et al, this volume).…”

Deep sea drilling on four seamounts in the Emperor Seamount chain revealed that Paleogene shallow-water carbonate sediments of the "bryozoan-algal" facies crown the basalt edifices. According to the biofacies model of Schlanger and Konishi (1966, 1975), this bryozoan-algal assemblage suggests that the seamounts formed in cooler, more northerly waters than those presently occupied by the island of Hawaii; i.e., the paleolatitudes of formation were greater than 20 °N. Moving southward toward the youngest member of the seamount chain, a facies gradient indicative of warmer waters was observed. This gradient is interpreted as a reflection of a northward shift in isotherms during the time span in which the seamounts were progressively formed (Savin et al., 1975). On all seamounts, sedimentation at the drilling sites occurred in a high-energy environment with water depths of approximately 20 meters. Early-stage carbonate diagenesis began in the phreatic zone in the presence of meteoric water, but proceeded after subsidence of the seamounts into intermediate sea waters, where the bulk, stable isotopic composition was determined. The subsidence into intermediate waters was rapid, and permitted establishment of an isotopic equilibrium which, like the facies gradient, reflects the northward shift in isotherms during the Paleogene. Calcite and zeolite cements comprise the later-stage diagenesis, and originated from solutions arising from the hydrolysis of the underlying basalt.In conclusion, the results of this study of the shallow-water carbonate sediments are not inconsistent with a paleolatitude of formation for Suiko Seamount (Site 433) of 26.9 ±3.5 °N, as determined by paleomagnetic measurements (Kono, this volume).

“…Isopachous cements are located in the whole grainstone layer, without any gradient of cementation (from the top to the base for example). Such early cements are common in shallow carbonate platforms and are interpreted as typical cement of a marine phreatic realm (Moore, 2001;Purser, 1969).…”

“…Oscillations between phreatic and vadose environments in early diagenesis can be explained by the coastal variations of the Tidalites de Vouglans associated with the regressive tendency of the Pürbeckian. Alternate wetting and drying of coarse sediments can be the cause of asymmetric cementation (Purser 1969;Fig. 5b).…”

Cement stratigraphy: image probes of cathodoluminescent facies

et al. 2011

Cement stratigraphy of carbonates aims to establish the chronology of processes involved in the rock diagenesis. Regional cement stratigraphy allows correlations and understanding of the petrological heterogeneities in reservoirs and aquifers, but is a long and rigorous approach. This article exposes a methodology of image analysis that facilitates the spatial correlation of diagenetic events in carbonate rocks. Based on the statistical comparison of signals extracted from the red spectrum emission of cathodoluminescence digital images, it gives via crosscorrelation a measure of similarity (values scaled from minimum -1 to maximum 1) between two cathodoluminescence facies. Cementation events and diagenetic chronologies can thus be quickly correlated without the support of a full chronology, the model normally established on cement morphologies, petrological analyses and cathodoluminescence zonation sequences. A case study from two Upper Kimmeridgian Mount Salève outcrops (France) illustrates this methodology. Their diagenetic sequences recorded in cathodoluminescent cements are presented and being compared. The final statistical similarity between the two outcrops reaches an index of R = 0.78. This result is sustained by petrological and geochemical analyses such as alizarine-ferricyanure stained thin sections, X microfluorescence mapping of elements, and microthermometry of fluid inclusions.
