Three BPSC workshops will take place on Sunday 3rd December, 2017 at the Scottish Universities Environmental Research Centre (East Kilbride, minibus transport from Glasgow) and the University of Glasgow (5-minute walk from the conference venue). Once registration opens there will be an option to register for the workshops (see registration form) in addition to the conference. Note places for the workshops are limited.
Workshop 1A: Geochronology of extraterrestrial materials
Led by: Prof. Darren Mark, Dr Ryan Ickert, and Dr Derek Fabel. Support will be provided by Dr Ben Cohen and Annemarie Pickersgill.
Workshop capacity: 15
Summary: Meteorites are samples of other (than the Earth) planetary bodies in our solar system, and except for the collection of returned lunar materials they are the only such samples available for laboratory examination. Since nearly all absolute chronometric methodologies require laboratory observation, meteorites provide the major basis for planetary chronology outside the Earth-Moon system. The principal non-laboratory approach to planetary chronology is analysis of impact crater density on the surfaces of major bodies observed remotely; such ages are considered in the articles for these planetary bodies, while this entry concentrates on the information which can be gathered from meteorites. This workshop will look at how we use radioisotopic and cosmogenic isotope dating to constrain the evolution of Mars and other solar system bodies. We will cover a range of techniques and include a series of laboratory visits (noble gas mass spectrometers, thermal ionization mass spectrometers, accelerator mass spectrometers).
The workshop will run at SUERC from 12:00 to 16:00. A minibus will take participants from the University of Glasgow to East Kilbride and return them to Glasgow.
Workshop 1B: The study of organic matter in extraterrestrial materials
Led by: Dr Queenie Chan, Dr Lydia Hallis and Prof. Monica Grady.
Workshop capacity: 15
Summary: Organic molecules are common on Earth, but certainly not limited to this occurrence in our solar system. The detection of organics in various solar system materials in the past decades have equipped us with a better understanding of the extensive array of organic materials that are present in meteorites, Earth-collected cosmic dust, as well as samples returned, or observed in situ by various space missions. Ahead of us are more exciting space missions with a clear target of investigating the molecular precursors that could have led to the origin of life. This workshop is designed to give an overall review of our understanding of the distribution of organic matter in our solar system. We will give an overview on the instrumentation commonly used to study the organic material (soluble and insoluble) in the laboratory, including various spectroscopic techniques such as Nanoscale secondary ion mass spectrometry (NanoSIMS), Raman, Fourier transform infrared (FTIR), X-ray absorption near edge structure (XANES), and gas chromatography mass spectrometry (GCMS), and will set foot in our BECS GC clean lab and Raman lab where we will demonstrate proper sample handling and data acquisition techniques. The workshop will be concluded by participants sharing tips/thoughts about sample handling skills and announcing new techniques/instrumentation offered in their universities/laboratories.
**Upon completion of this workshop, participants can apply for free instrumental time (up to 4 hours) on the Renishaw InVia Raman Microscope of the School of Geographical & Earth Sciences, University of Glasgow.
^BECS: Biomarkers for Environmental and Climate Science
Workshop 1C: Characterisation of crystalline materials by EBSD, TKD and TEM
Led by: Dr Luke Daly and Prof. Martin Lee.
Workshop capacity: 15
Summary: Microstructural textures and defects in minerals from rocks including meteorites and terrestrial impactites are used to interpret their petrogenesis, i.e., shock and thermal histories. Electron backscatter diffraction (EBSD) and its high-resolution sister transmission Kikuchi diffraction (TKD) as well as transmission electron microscopy (TEM) are powerful tools for extracting such crystallographic information. The workshop is designed to give an overview of these techniques, the principles behind them and the information that can be obtained from them. This is followed by a live demonstration on the EBSD system at the University of Glasgow, School of Geographical and Earth Science and a crash course in data reduction and interpretation using Oxford Instruments Channel 5 software package. We will also have a session to discuss challenges for EBSD, TKD and TEM such as sample preparation, or temperamental phases where we can share our experience and devise solutions.
