Sedimentary Geochemistry and Biogeochemistry: A Guide to Interpreting Ancient Organic-Rich Mudstones, Their Solid-Phase Components and Organic Carbon Preservation

12 November 2014
Houston, Texas, United States
Who Should Attend
Geologists, geophysicists, petrophysicists and/or petroleum engineers who work in unconventional shale resource plays and who use geochemical data to better understand their reservoirs. This course is also appropriate for industry professionals who are seeking an introduction to geochemistry and chemostratigraphy as it relates to organic rich source rocks. Elemental and mineralogical datasets are becoming routine with shale reservoir analysis, and this course provides the framework to interpret those data.

By the end of this course, participants should be able achieve the following:

  • Define solid-phase inputs of sediments, the origin and genesis of these inputs
  • Interpret major elements and bulk mineralogy to identify their origins
  • Describe the types of deep sea sediments and trends in geographic distribution
  • Define modes and delivery of sediment inputs to the margins and ocean basins
  • Describe carbonate equilibria in the oceans and its influence on carbonate deposition
  • Identify the differences between deep water and shallow carbonates
  • Classify the various biogeochemical zones in organic rich sediments
  • Describe reduction-oxidation reactions that drive biogeochemical zonation
  • Define and interpret authigenic minerals associated with early diagenesis
  • Interpret major and trace elements in the context of these redox conditions
Course Content

This course is designed to present the concepts of sedimentary geochemistry and biogeochemistry, along with the framework to interpret elemental and mineralogical records in such organic rich mudstone sequences. This course will focus on concepts as opposed to quantitative analysis, though some computations and chemical reactions will be discussed as they relate to biogeochemistry and carbonate equilibria. In addition, this course will also define the cascade of biogeochemical zones associated with early oxidation of organic matter. These biogeochemical zones occur in numerous environments from shallow estuaries to the deep ocean, and are also highly variable depending on the depositional settings. Typical pore water profiles, chemical reactants and products will be covered. Geochemical cycling in organic rich sediments also generates authigenic minerals, which can be diagnostic of oxic versus dysoxic, and/or sulfidic (euxinic) sedimentary conditions. The archetypal authigenic minerals and their associated elemental composition will also be discussed in the context of interpreting redox history within a sedimentary basin.

Course notes will be provided in digital format on USB flash drive only, so electronic devices with a USB port are required for all courses. If you do not have access to an electronic device with a USB port, please contact the AAPG Education Dept. for an alternate method to download the digital course notes.
