Unit description
This unit provides the foundations for analysing the chemical composition of sedimentary rocks and fluids such as oils and gases, and especially the organic constituents. This unit will showcase organic geochemical techniques and will be strongly practically based. It will cover the following topics: (i) Samples and preparation, (ii) Microscopy and microprobe, (iii) Bulk/solids analysis, including elemental analysis, total organic carbon and pyrolysis techniques such as Rock-Eval, MSSV and laser micropyrolysis, (iv) Spectroscopic methods such as NMR, Raman and FTIR, (v) Solvent extraction of rocks and fractionation of totals extracts and oils, (vi) Gas chromatography-mass spectrometry, including MS-MS and GCxGC Time-of-Flight Secondary Ion Mass spectrometry, and (vii) Stable C, H, N, O and S isotopes of sedimentary rocks and fluids such as oils and gases. Experience will also be gained in the manipulation and interpretation of data generated by these techniques. Lastly, these techniques will be applied to understanding petroleum systems and to deconvoluting the Precambrian biosphere.

Delivery and Resources
GEOS710 Records of palaeoenvironments: life and geochemistry (session 2, 2016)
This unit will provide masters students with the foundations of palaeoenvironmental analysis as applied to some key geoscience problems. The unit will have a problem-based approach and will focus on understanding important processes, especially with examples from the Neoproterozoic, Cretaceous and the modern day. Fundamentals of ocean circulation, nutrient supply and the carbon cycle will be introduced. The veracity of biogeochemical oceanographic signals will be assessed, especially with respect to diagenetic overprinting. Box models will be introduced as a means for understanding geochemical and isotopic signals. The unit will cover co-evolution of life and its environment, the effect of bioturbation on sediments, especially across the Precambrian-Cambrian boundary, and the geochemical record of life as expressed through biomarkers. The pros and cons of various proxies used for the reconstruction of palaeotemperatures will be assessed. The unit will build knowledge about important techniques and methods such as stable and radiogenic isotopes, organic geochemistry and microscopic techniques for assessing sediments and sedimentary rocks. Assignments will be designed to build high level research skills in this area.
This unit is co-taught with GEOS920 Palaeoenvironments and biogeochemistry (Master of Geoscience). The lectures are the same, but the assignments differ slightly due to different learning outcomes. There is only one iLearn site for both units.
Web pages and electronic resources
The main unit web page will be on iLearn: https://ilearn.mq.edu.au/login/MQ/
iLearn is Macquarie's learning management system. Assignments, hand-outs, and reading material will be available here.
Classes: There will be 13 compulsory lectures/tutorials to introduce the unit and give you a grounding in the theory behind some of the techniques. It is important that you attend these sessions every week, as they include discussion sections, and also problem solving on hard copy handouts. The sessions will be audio recorded, and will be available direct from the iLearn site for your later review and revision. These classes- will be in W5C 302, Tuesday 3-5 pm.

Changes from Previous Offering
The unit has been completely restructured since 2015. The practical component has been completely removed (can now be done as part of GEOS791). The breadth of the unit has been much widened from the original organic geochemistry, and involves 3 new teaching staff (April, Martin, Stefan). There are new assessments, and lectures and tutorials are mostly new in 2016. The class test has been removed.
