Abstract Petrography, fluid-inclusion microthermometry, stable isotope analyses, and radiometric (206Pb/238U) dating of Upper Triassic dolostones, saddle dolomite, quartz calcite cements were used to constrain the timing conditions dolomitization cementation in context tectonic evolution a basin northern United Arab Emirates. Dolomitization (ca. 152.4 Ma) precipitation dolomite 146.8 Ma), 144.6 are attributed focused synrifting flow hot basinal brines into grain-supported limestones which...
Field observations, together with the results of gas chromatography–mass spectrometry (GC-MS) and stable carbon isotope analysis bitumen, coupled fluid inclusion microthermometry analyses closely associated vug- fracture-filling columnar calcite in Upper Cretaceous Bekhme Formation, Kurdistan Region Iraq, suggest that degradation crude oil was caused by regional incursion meteoric waters. This incursion, which is interpreted to have occurred during tectonic uplift Zagros Orogeny, evidenced...
While the characteristics and origin of drusy calcite cement in carbonate deposits is well constrained literature, little attention paid to dolomite cement. Petrographic observations, stable isotopes, fluid-inclusion microthermometry suggest that Permo-Triassic conglomerate/breccia dolostone beds northern United Arab Emirates has precipitated as not by dolomitization The low δ18OVPDB (−9.4‰ −6.2‰) high homogenization temperatures fluid inclusions (Th = 73–233 °C) was caused hot basinal...
ABSTRACT Continental red beds are coloured by secondary Fe(III)‐oxy‐hydroxides (mainly hematite) which makes them excellent archives of ancient near‐surface redox conditions. However, colour is often treated as a subjective physical property, and opinions differ widely to the environment timing colouration beds. This study utilizes diffuse spectral reflectance address degree reddening (hematitization) Siluro‐Devonian Old Red Sandstone representing dryland fluvial system with abundant...
The texture and chemical compositions of secondary Ca–Al silicates (prehnite, pumpellyite, epidote, titanite) related minerals (chlorite, sericite, K‐feldspar, albite, Fe‐oxides, fluorite, calcite) are used to discuss their formation conditions during interaction Proterozoic granitic rocks from SE Sweden with hydrothermal fluids. paragenetic sequence the is suggested have been accomplished at ca. 200–350°C was controlled by small‐scale variations in chemistry fluids, such as a Ca 2+ /a H +...
