Stephen Wegner BSC Hons MAIG
BACKGROUND
Stephen attained his Earth Science degree with Honours from James Cook University in 1992.
His Honours thesis entailed field mapping, petrographic and geochemical analysis of magma mixing across the Mt. Stuart Igneous complex, including detailed evaluation of various melt enclaves and xenoliths of pyroclastic country rocks.
He worked in the JCU Advanced Analytical Centre after his thesis, and gained experience in a range of analytical techniques (Wet Chemistry, XRD, XRF, Microprobe, ICPMS, Infrared Spectroscopy, Scanning Electron Microscopy). Client projects he was involved with were dominantly earth science, mining and exploration (mineral and coal) but he also assisted with a number of analyses involving forensic investigations for the Queensland Police.
Stephen undertook postgraduate studies for five years examining the metamorphic, structural and igneous history of the Barnard Metamorphics (Tully to Cairns) and its regional relationship to adjacent Hodgkinson Formation. This entailed extended field mapping (120x30km) across a deeply weathered rainforest coastal terrain; over 1000 large-format thin sections (many structurally oriented pairs); a large number of microprobe analyses; and numerous whole rock geochemical analyses on a range of lithologies from multiply deformed granites to ultramafics. During this time he was a senior tutor and curator for the JCU department of earth sciences. Stephen also taught hands on rock and mineral identification for 3rd year civil engineers including field trips to quarries and a civil structure of concern.
After JCU, Stephen worked at Phosphate Hill (central far west Qld) as a mine geologist where he assisted further with groundwater monitoring, and a beneficiation study into lithology variations, which included petrographic analyses that provided a significant change in understanding of ore characteristics.
With family commitments Stephen worked nine years in a Townsville-based environmental business. Over this period he conducted a range of scientific investigations into environmental problems across mining and industrial sites that entailed groundwater, soil and sediment contamination; failure of waste containment and civil structures (construction material quality); rock-sediment-soil mineralogical and geochemical characterisation; hydrogeology; mine rehabilitation; and some ore beneficiation investigations.
Experience in mineralogical characterisation of phosphorite, coking coal inorganics, coal seam gas skin damage, iron ore, magnetite, graphite, zeolite, hydrothermal gold, and rock suitability for the range of construction stone materials.
Pterosaur Petrology was established in 2015, and has been consulting across North Queensland for a number of quarry operations, mines, excavation, exploration and civil engineering companies with an emphasis on quality geology, mineralogy and geochemistry.
Member of the Australian Institute of Geoscientists (AIG # 3942), and Member of the Economic Geology Research Unit (EGRU) James Cook University.
