“…Many of the attributes documented for modern and ancient tidal sand ridges, in both siliciclastic-dominated and carbonate-dominated case studies (Houbolt, 1968;Pryor et al, 1990;Davis & Balson, 1992;Keith & Zuppann, 1993;Hulscher, 1996;Saito et al, 1998;Reynaud et al, 1999;Bern e et al, 2002;Park et al, 2006;Reeder & Rankey, 2008;Chiarella et al, 2020) resemble the characteristics observed in the studied succession of the Siderno Basin. Particularly, superimposed dunes migrating obliquely with respect to the ridge axis and the tripartite facies association recording nucleation, accretion and abandonment of the ridge are common distinctive elements of these systems (Caston, 1972(Caston, , 1981McCave & Langhorne, 1982;Huthnance, 1982a;Huthnance, 1982b;Howarth & Huthnance, 1984;Gaynor & Swift, 1988).…”

Sand ridges, a common feature of modern open shelves, reflect persistent currents and sediment availability under recent transgressive conditions. They represent the largest bedforms in the oceans and, as such, can yield information on long-term oceanographic processes. However, there is a limited number of tidal sand ridges documented from the rock record, examples of regressive tidal sand ridges are scarce and studies describing ridges in straits are even more rare. This study analyses a Gelasian succession within a structurally controlled, tide-dominated strait in the Siderno Basin, southern Italy. The strait connected two wider basins, and accumulated sediments reworked by amplified tidal (bi-directional) currents. A series of tidal sand ridges with superimposed dunes developed close to the south-eastern end of the strait, where bathymetry was deeper and flow expansion occurred. One of the best-exposed tidal sand ridges, 65 m thick, crops out along a ca 2 km long cliff. Large-scale, ESE-prograding, seaward-offlapping shingles contain sets of bioclastic-siliciclastic, coarse-grained, cross-stratified sandstones, erosionally overlying upper Pliocene shelf marls and fine-grained sandstones. Cross-strata show angular, tangential and sigmoidal foresets with compound architectures and a SSE migration, i.e. oblique to the main growth direction.Fossil content indicates open-marine conditions. The succession changes abruptly across an erosion surface to non-tidal, highly burrowed mixed siliciclastic-bioclastic fine-grained sandstones, less than 15 m thick. Documented features reflect stages of nucleation, active accretion and abandonment of an individual sand ridge, during a complete cycle of relative sea-level change. The ridge formed during a phase of normal regression, with accretion occurring during an initial highstand and the ensuing falling stage.

“…Other significant occurrences of hydrocarbon-rich reservoirs characterized by prominent oomoldic porosity in the United States include the Mississippian units in the Anadarko Basin and Hugoton Embayment, the Greenbrier and Monteagle limestones of the Appalachian Basin, and the Madison Group of the Williston Basin (Keith & Zuppann, 1993). The Jurassic Arab-D reservoirs of Saudi Arabia, arguably the largest oil-bearing oolitic unit in the world, has bimodal porosity with oomoldic pores locally contributing to better reservoir zones (Lindsay et al, 2006).…”

Dissolution of ooids in seawater‐derived fluids – an example from Lower Permian re‐sedimented carbonates, West Texas, USA

Selective dissolution of metastable minerals and certain pore types, such as moldic and oomoldic pores, are widely accepted to indicate diagenesis by meteoric fluids in carbonate rocks. In this study, oomoldic-rich re-sedimented carbonates from the Happy Field in the Midland Basin, which contain no evidence of subaerial environments, indicate that such pores may form in other settings. Ooid dissolution in the reservoir was evaluated through petrography, scanning electron microscopy, stable isotopes (d 18 O and d 13 C), elemental geochemistry, and X-ray diffraction of bioclasts, ooids and associated cements. Cements are primarily dogtooth and equant low-magnesium calcite, poikilotopic celestine is present, and late-stage low-magnesium calcite occurs in lesser amounts. Equant low magnesium calcite cements are interpreted to reflect the initial stages of pore filling, synchronous with aragonitic ooid dissolution, thus implying that oomoldic pores and equant cements formed in similar fluids. Although the prominent equant low magnesium calcite cement textures mimic those often associated with meteoric fluids, geochemistry suggests a marine origin. The equant cements have d 18 O (Vienna Pee Dee Belemnite) ratios between À2.0& and À3.5&, and d 13 C (Vienna Pee Dee Belemnite) ratios between 4& and 5&. Magnesium/calcium ratios show values, ranging from 5 to 142 mmol/mol (n = 223, average 23.2 and SD = 20.1). Strontium/calcium ratios present values from 0.3 to 2.6 mmol/mol (n = 223, average 0.71 mmol/mol, SD = 0.35). Geochemical data coincide with typical lowlatitude Permian marine carbonate values and further signify diagenesis within the marine phreatic realm. To explain this process, the results indicate that the dissolution of aragonite ooids and precipitation of early cements occurred in environments ranging between the seafloor to shallow burial dominated by undersaturated marine fluids. Undersaturation was triggered by organic matter decomposition occurring at the seafloor and in the shallow subsurface immediately below. These findings have broader implications for marine and burial carbonate diagenesis as well as diagenesis of re-sedimented deposits.
