b'ASEG newsBranch news(SMEDG). The presentation was entitled The seven deadly sins of scale: why petrophysics + structure + mineralogy can solve the scale paradox. Jim explored relationships between geology, petrophysics and geophysics. The first half was devoted to exploring some of the seven of the most common petrophysical pitfalls that lead to misinterpretation of magnetic data, including lightning induced and drilled induced magnetisation. He then outlined the integrated petrophysics approach and illustrated how to integrate and use petrophysical data to upscale mineral system knowledge from the sample scale to drilling scale and beyond, citing case histories on IOCG, magnetite and Barry Bourne addressing the WA audience at the beginning of his well-attended and inspiring talk. magmatic nickel deposits across Australia.are most commonly obtained at roomBig Data.
