    Fluid-inclusion petrography in calcite stalagmites: Implications for entrapment processes
    (SEPM (Society for Sedimentary Geology), 2021) López Elorza, Maialen; Muñoz García, María Belén; González Acebrón, Laura; Martín Chivelet, Javier
    Fluids trapped in speleothems have an enormous potential in frontier fields of paleoclimate and paleohydrological research. This potential is, however, hampered by diverse scientific and technical limitations, among which the lack of a systematic methodology for genetically characterizing fluid inclusions is a major one, as these can have different origins, and thus, the trapped fluid (usually water), different meanings. In this work, we propose a systematic petrological classification of fluid inclusions, based on: 1) the temporal relation between fluid inclusions and the host calcite, 2) the spatial relation between fluid inclusions and the “crystallites” and crystals aggregates, and 3) the phases (water, air) trapped inside fluid inclusions. The first criterion allows dividing fluid inclusions in two main categories: primary and secondary, whose identification is critical in any research based on trapped fluids. The other two criteria allow the definition of eight types of primary and four types of secondary fluid inclusions. Primary fluid inclusions contain the drip water that fed stalagmites at the time of crystal growth, and can be intercrystalline, i.e., located between adjacent crystallites, or intracrystalline, i.e., with the fluid trapped within crystallites. We differentiate six main types among the intercrystalline fluid inclusions (elongate, thorn-shaped, down-arrow, interbranch, macro-elongate, and bucket) and other two among intracrystalline inclusions (pyriform and boudin). In primary inclusions, water is the main phase, while gas is much less abundant. The presence of gas could be related to slow drip rates or degassing in the cave, but also to later leakage due to changes in temperature and humidity often occurring during inadequate handling of speleothem samples. Secondary fluid inclusions were clearly related to younger water inlet through stratigraphic disruptions or unconformities. They are formed after water infiltration, but sealed before the renewed crystal growth. We differentiate four main types of secondary inclusions: interconnected, rounded, triangular, and vertical fluid inclusions. The identification of primary and secondary fluid inclusions in speleothems is a key for interpretation in paleoclimate studies. Integration of petrological results allow establishment of three different genetic scenarios for the formation of fluid inclusions, whose identification can be relevant because of their predictive character.

    Sedimentary evolution of tectonically-controlled Cenozoic shallow marine glaucony, fluviatile and lacustrine-palustrine deposits at Bahariya region, Egypt
    (Elsevier Science, 2022-06) Afify, A.M.; Sanz Montero, M. Esther; González Acebrón, Laura; Muñoz García, María Belén
    The Cenozoic basin of the tectonically-active Bahariya region (Western Desert, Egypt) contains a unique paleoenvironmental, paleotectonic and paleoclimatic record displaying a large variety of sedimentary facies, stratigraphic discontinuities, and geochemical changes. This study deals with the sedimentary evolution and tectono-stratigraphic modelling of shallow marine Upper Eocene glaucony facies (Upper Hamra Formation) that changes upward into a sequence of Oligocene continental fluviatile sandstone-calcrete (Radwan Formation) and then into Miocene lacustrine-palustrine deposits (Continental Carbonate Unit). The tectonic instability of the Bahariya basin can be deduced from occurrence of sedimentary discontinuities, development of pedogenic features, and unconformable relations among rock units. Both sedimentation pattern and facies distribution seem to have been controlled by fault activity through time. Two types of glaucony facies (pelloidal and massive smectitic glaucony) were deposited in a narrow sub-basin along main faults reaching the basin center. These faults also conditioned the deposition of the Oligocene fluviatile sandstone and Miocene lacustrine-palustrine carbonates. A transition from greenhouse (global warming event of the Middle Eocene Climatic Optimum) to icehouse climatic conditions (Eocene-Oligocene climatic cooling) is probably represented by the deposition of the shallow marine glaucony facies during the Priabonian. Semi-arid to sub-humid conditions were dominant during the formation of the Oligocene calcretes and the Miocene lacustrine-palustrine carbonates. The latter carbonate deposits consist of basal thin-bedded chert deposits displaying hydro-plastic sedimentary structures that are possibly coeval with the Miocene basaltic extrusions along faulted and low-lying areas. We conclude that both paleoclimate and intraplate tectonic activity related to the Red Sea rifting influenced the pattern of sea level, continental drainage, sedimentation rate and clastic supply since the Priabonian up to the middle Miocene in the Bahariya basin.
