- Inactive for Year: 2018/19

|Semester 1 Credit Value:||10|
To provide the science basis of organic matter in sedimentary rocks and to understand the combination of factors that result in the formation of hydrocarbon source rocks and anoxia/euxinia in lacustine and marine environments. Geochemical techniques are introduced that allow reconstructing the origin, fate during transport and after burial, and hydrocarbon source rock potential of sedimentary organic matter.
Organic matter controls in modern and past marine settings; Productivity, carbon flux, and organic carbon burial; Early diagenetic processes; Ocean dysoxia-anoxia; Oxygen Minimum Zones and upwelling; relationship to sea level change and widespread volcanic activity; ancient sapropel and black shale; Oceanic Anoxic Events; Analytical toolbox including; geochemical bulk proxies (C/H/N, Rock Eval Pyrolyses), molecular tracers (photic zone euxinia), inorganic redox tracers (redox-sensitive trace elements, C-S-Fe relationships; novel isotopic approaches).
Outline Of Syllabus
Geological and sedimentary context;
Petroleum source rocks: characteristics observed in outcrops and drill cores;
Production and distribution of organic matter in the modern ocean;
Sedimentation rate, accumulation rate, oxygen exposure time;
Near-surface diagenesis of organic matter;
Anoxic settings: modern and past;
The ‘Productivity’ versus ‘Preservation’ debate.
Bulk geochemical characterization of sedimentary organic matter (bulk C isotopes, Rock Eval, C/N);
Sedimentary tracers for ocean anoxia (I): Inorganic geochemistry (redox sensitive trace elements, Fe-C-S relationships);
Sedimentary tracers for ocean anoxia (II): organic geochemistry (bottom water and photic zone anoxia markers).
Petroleum source rocks and climate:
Oceanic Anoxic Events: general concept and stratigraphic occurrence;
Oceanic Anoxic Events: high resolution records from past greenhouse oceans.
Introductory field trip to the Jurassic N Yorkshire Coast (one day).

Teaching Rationale And Relationship
Knowledge and advanced understanding are delivered via lectures, independent literature review and writing of a scientific essay, and a one day field course. Observations and discussions during the field course will further aid the development of integrated (geological) understanding.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The general and specialist knowledge and understanding are assessed by means of unseen written examination and a single scientific essay (coursework). The examination paper covers a broad range of subjects and approaches to accurately and balanced assess the student's abilities. These may include essay, data interpretation and multi-part questions.
