Regional cementation from unconformity-recharged aquifer and burial fluids, Mississippian Newman Limestone, Kentucky

Developing concepts of high-resolution diagenetic stratigraphy for Pliocene cool-water limestones in New Zealand, and their sequence stratigraphy

“…CL zonations in clear spar cements are assumed to be due to changes in porefluid chemistry, so that each zone may represent a timecorrelative discrete period of cementation. It appears that it is mainly variations in the contents (or ratio) of Fe and Mn that control calcite luminescence (Dorobek 1987;Niemann and Read 1988;Horbury and Adams 1989;Meyers 1989).…”

“…Other studies have shown that the lateral distribution of cement zones may be continuous over several kilometres (Dorobek 1987;Kaufinan et al 1988;Niemann and Read 1988) or discontinuous even over short distances (Machel and Burton 1991). Also individual cement zones may not be isochronous throughout a particular area due to the 67 progressive displacement of ground waters through strata (Frank et al 1995), or the repetition of the same diagenetic motif at different stratigraphic levels due to the occurrence within the succession of subaerial exposure surfaces and/or to the fluctuation of water tables (Walkden 1987;Goldstein 1988).…”

Hydrothermal Dolomites in the Early Albian (Cretaceous) Platform Carbonates (NW Spain): Nature and Origin of Dolomites and Dolomitising Fluids

“…Calcitised, non-luminescent part of CCD-I represent less depleted δ 18 O and depleted δ 13 C values (Fig. 11a, b), likely formed near meteoric recharge (Choquette and James, 1988;Niemann and Read, 1988;Meyers, 1991;Reeder, 1991).…”

The effect of meteoric phreatic diagenesis and spring sapping on the formation of submarine collapse structures in the Biak Basin, Eastern Indonesia

“…Fresh water has been reported in a well 100 km off shore Florida in the Gulf of Mexico, 10 km offshore of Saudi Arabia and offshore Bahrain in the Persian Gulf, and beneath the continental shelves of the North Atlantic (Kohout, 1966;Fetter, 1980;Chafetz et al, 1988;Chafetz and Rush, 1995;Edmonds, 2001;Wu and Chafetz, 2002;Person et al, 2003;Fleury et al, 2007). Meteoric diagenesis of ancient carbonates through lateral flow of fresh water in palaeoaquifers is also well-documented (Grover and Read, 1983;Dorobek, 1987;Niemann and Read, 1987;Wu and Chafetz, 2002;Moore and Wade, 2013).…”
