Book Description :

The early Cambrian evolutionary development of animals capable of significant bioturbation may have affected the burial efficiency of organic carbon in marine sediments. Late early Cambrian shelf sediments contain evidence of a significant increase in the intensity and depth of bioturbation. delta 13C values in similar aged sediments show decreases in the frequency and amplitude of variability, as well as a shift to lower average isotopic values, consistent with a reduction in the mass fraction of organic carbon (Xorg) preserved in marine sediments.

Book Description :

This study established the sequence stratigraphic framework of the Cyrenaican Miocene through the integration of the sedimentology, stratigraphy, gamma-ray logs, chemostratigraphy, and diagenesis. Carbon-isotope curves and gamma-ray logs with sedimentologically described measured stratigraphic rock sections of the Ar-Rajmah Group were implemented to define facies depositional models and their sequence stratigraphic patterns within a high resolution timeframe. The Ar-Rajmah Group of the Cyrenaican Miocene includes the Benghazi Formation and Wadi-al-Qattarah in the Al-Jabal al-Khdar north, and its equivalent Msus and Sceleidima formations in the Soluq Trough south. The Cyrenaican Miocene is made up of two 2nd-oreder sequences (SS1-SS2) that includes six 3rd-order sequences (S1-S6), and at least 20 parasequences. The 3rd-order sequences S1 and S2 represent the Early Miocene and are dominated by open marine bioclastic packstone and red algal packstone facies. The Early Miocene SS1 is separated from the Middle and Late Miocene SS2 by a major unconformity surface. The Middle Miocene is represented by the 3rd-order sequence S3 that dominated a mixture of oolitic grainstone, microbialites, and bioclastic packstone, red algal packstone, with evaPorites, sandstone and green shale. The 3rd-order sequences S4-S6 represent that Late Miocene sequences and dominated by oolitic grainstone, microbialites, with evaPorites and some bioclastic packstone and red algal packstone facies. The correlation between the Cyrenaican stratigraphic record and the regional Mediterranean and global Miocene isotope records, and global sea level curve indicates that the 3rd-order depositional sequences of the Cyrenaican platform were affected by a tectonic signature besides the eustatic sea level fluctuations. The Cyrenaican Miocene sea level curve does not show a great similarity with the global sea level curve due to the tectonic influence. Microscopic analysis, stable isotope data, and trace elements were implemented to define the diagenetic events. Cross-cutting relationships were applied to define the paragenetic sequence of the diagenetic events within the stratigraphic framework of the Cyrenaican Miocene succession. The Ar-Rajmah Group carbonate rocks were affected by 18 diagenetic events caused by six diagenetic processes including the meteoric water diagenesis.

Book Description :

Strata of the Eagle Ford Group of South Texas, deposited during the Cenomanian and Turonian of the Late Cretaceous, are largely characterized as mixed siliciclastic and carbonate mudrocks rich in organic carbon. The Eagle Ford Group records deposition within the Maverick Basin, along the Comanche Shelf, at the southern margin of the Western Interior Seaway in present-day South Texas. In recent years, the Eagle Ford has emerged as one of the premiere petroleum plays, as it has been proven to be capable of producing significant volumes of dry gas, wet gas/condensates, and oil. It is believed the Eagle Ford represents deposition during the globally correlative Ocean Anoxic Event #2, characterized by the accumulation and preservation of vast amounts of organic carbon due to the expansion of large deep-water oxygen minimum zones. This study integrates geochemical analyses of six drill cores from Gonzales, Guadalupe, La Salle and Wilson counties of South Texas. These cores were studied to determine bulk geochemistry, redox conditions, and degree of basin restriction and deepwater renewal times in order to provide a detailed assessment of the chemostratigraphy and paleoceanography of the Eagle Ford Group. Each core was scanned at one foot intervals with a handheld X-ray fluorescence (XRF) spectrometer to obtain quantitative measurements of major elements, such as Ca, Al and Si, as well as redox sensitive trace metals, such as V, Zn, Ni and Mo. In addition, some cores were analyzed for total organic carbon (TOC), total inorganic carbon (TIC), and stable isotope ([delta]13C and [delta]18O) signatures of the inorganic, carbonate component. The elevated levels of redox sensitive trace metals of the Lower Eagle Ford, represented here by the Lake Waco and Pepper Shale Formations, reveals deposition during a time of anoxic or euxinic conditions leading to the preservation of large amounts of organic carbon (~5% TOC). The South Bosque Formation, representing the Upper Eagle Ford, displays reduced levels of these trace metals, suggesting a return to a more oxygenated environment prior to the deposition of the overlying, fully oxygenated and heavily bioturbated Austin Chalk. The physical paleoceanography of the Eagle Ford is revealed to be restricted at times and more open at others with lower deep-water renewal times, yet remained mainly within an anoxic or euxinic state. In regard to the inorganic stable isotopic data, the [delta]13C carb values, which other studies have shown to display a positive excursion at the time of OAE2, suggest this event is not preserved within the cores analyzed.

Book Description :

Handheld energy dispersive x-ray fluorescence spectrometry (ED-XRF) is routinely used to observe elemental variability in fine-grained siliciclastics but has been applied rarely in fine-grained carbonates. Here, ED-XRF chemostratigraphy is utilized in the texturally homogenous, mudstones of the Silurian A-1 Carbonate (A-1C), Michigan Basin. Previous studies on the A-1C focused on the stratigraphic relationship with the underlying Niagaran reefs, so little is known about the geological variability in the basin center. In this study, high-resolution elemental data from nine cores were integrated with petrographic and mineralogical observations to evaluate two hypotheses: (1) Texturally homogeneous, basin-center mudstones in the A-1C have spatially correlative elemental signatures (i.e. chemofacies); (2) Elemental variations reflect temporal changes in relative sea-level, redox conditions, and sedimentation rate. Spatially correlative temporal variations in Si, Al, K, and S are observed between basin-center wells. High abundances of Si, Al, and K associated with siliciclastic minerals are interpreted to reflect intensification of clastic sedimentation during low sea-level. Associated S increases are interpreted as diagenetically altered gypsum that was deposited during periods of low sea-level. Chemofacies successions indicate 6 low-order transgressive-regressive cycles and up to 14 high-order cycles. These findings demonstrate the ability of ED-XRF to provide geologically relevant elemental data that can be used to refine sequence stratigraphic interpretations in fine-grained carbonates.
