“…These sediments underwent cementation from percolating fluids and localized recrystallization as a result of heating from the overlying impactites (Lueders and Rickers 2004). Post-impact sediments were mostly consolidated due to dolomitization and carbonate precipitation (Lefticariu et al 2006 Formation resistivity factor Figure 11 shows a negative correlation between formation resistivity factor F and porosity F in accordance with literature (''Archie's first law''):…”

Internal surface, formation factor, Nuclear Magnetic Resonance (NMR)-T2 relaxation times and pore radius distributions were measured on representative core samples for the estimation of hydraulic permeability. Permeability is estimated using various versions of the classic Kozeny-Carman-equation (K-C) and a further development of K-C, the fractal PaRiS-model, taking into account the internal surface. In addition to grain and pore size distribution, directly connected to permeability, internal surface reflects the internal structure (''micro morphology''). Lithologies could be grouped with respect to differences in internal surface. Most melt rich impact breccia lithologies exhibit large internal surfaces, while Tertiary post-impact sediments and Cretaceous lithologies in displaced megablocks display smaller internal surfaces. Investigations with scanning electron microscopy confirm the correlation between internal surface and micro morphology. In addition to different versions of K-C, estimations by means of NMR, pore radius distributions and some gas permeability measurements serve for cross-checking and calibration. In general, the different estimations from the independent methods and the measurements are in satisfactory accordance.For Tertiary limestones and Suevites bulk with very high porosities (up to 35%) permeabilites between 10 -14 and 10 -16 m 2 are found, whereas in lower Suevite, Cretaceous anhydrites and dolomites, bulk permeabilites are between 10 -15 and 10 -23 m 2 .

“…The suevitic breccias that are impact melt-rich, polymict debris were likely deposited from the ejecta plume and collapsed central peak (Kring 2005;Wittmann et al 2007). The overlying carbonate sediments were deposited from a shallow Tertiary ocean after infilling of the crater (Stinnesbeck et al 2004;Lefticariu et al 2006).…”

“…With a presumed total extension of 7000 km, the Yucat an subterraneous karst cave system is among the most extensive active cave systems worldwide, with an explored length of >1000 km (Bauer-Gottwein et al, 2011;Kambesis and Coke, 2013;Quintana Roo Speleological Society, 2014). The system perforates almost horizontally layered, thick-bedded, shallow-water carbonate bedrock that developed during the Mio-, Plio-and Pleistocene (Weidie, 1985;Lefticariu et al, 2006). Karstification maxima existed during Pleistocene glacial stages (Ward, 1985) when sea level was more than 100 m below present-day sea level (bpsl; Blanchon and Shaw, 1995;Moseley et al, 2013).…”

Numerous charcoal accumulations discovered in the submerged Chan Hol cave near Tulum, Quintana Roo, Mexico, have been 14C‐dated revealing ages between 8110 ± 28 14C a BP (9122–8999 cal a BP) and 7177 ± 27 14C a BP (8027–7951 cal a BP). These charcoal concentrations, interpreted here as ancient illumination sites, provide strong evidence that the Chan Hol cave was dry and accessible during that time interval. Humans used the cave for at least 1200 years during the early and middle Holocene, before access was successively interrupted by global sea level rise and flooding of the cave system. Our data thus narrow the gap between an early settlement in the Tulum area reaching from the late Pleistocene (∼13 000 a) to middle Holocene (e.g. 7177 14C a BP), and the Maya Formative period at approximately 3000 a bp. Yet, no evidence has been presented to date for human settlement during the ∼4000‐year interval between 7000 and 3000 a. This is remarkable as settlement in other areas of south‐eastern Mexico (e.g. Chiapas, Tabasco) and in Guatemala was apparently continuous.

“…Cenote 13 had a higher K + concentration (0.3 meq L 21 ) in all seasons probably due to the use of fertilizers in the concentrations were highest in cenotes 1 through 7 in the west. This ion originates from seawater and dissolution of dolomite and evaporites (Custodio andLlamas, 1983, p. 1012), suggesting that the high concentrations could be due to seawater encroachment or the presence of dolomite and low-Mg calcite (Lefticariu et al, 2006). SO 4 22 behavior was similar to that of Mg 2+ .…”

Assessing water quality in aquifers has become increasingly important as water demand and pollution concerns rise. In the Yucatan Peninsula, sinkholes, locally known as cenotes, are karst formations that intercept the water table. Cenotes are distributed across the peninsula, but are particularly dense and aligned along a semicircular formation called the Ring of Cenotes. This area exhibits particular hydrogeological properties because it concentrates, channels, and discharges fresh water toward the coasts. In this study, we identify spatial and temporal variations in chemical and physical variables at twenty-two cenotes to identify groups that share similar characteristics. Water samples from each cenotes were taken at three depths (0.5, 5.5, and 10.5 m) and during three seasons (dry, rainy, and cold-fronts season). Field measurements of pH, temperature, electrical conductivity, and dissolved oxygen were taken, and the concentrations of major ions (K + , Na + , Mg 2+ , Ca 2+ , HCO 3 ) were quantified. Identifying regions of the cenotes were done by applying multivariate statistical techniques (PCA, PERMANOVA, CAP). The chemical variables revealed spatial trends among the cenotes. We identified three main regions. Region 1 is associated with sea-water encroachment and high levels of sulfate that travel through preferential groundwater flowpaths from evaporites in the southern Yucatan Peninsula; Region 2 is a recharge zone, and Region 3 is characterized by sea water encroachment and by the high chemical and physical variability associated with groundwater flow from the east.
