Ep 145: Convolution is not what happens to your cables in the field truck! Part 2
Episode 145
Wednesday, 28 January, 2026
Gregory Zhang (Senior Geology Consultant) to talk about what convolution actually means in a geostatistical and geological context, and how it shows up in tools ranging from moving averages to convolutional neural networks (CNNs). Building on part one of the conversation, they focus on practical use, common pitfalls, and how to combine modern machine learning approaches with classic geostatistics without losing geological control. Key moments 00:02 – What convolution means in day-to-day geology and resource work 00:51 – Moving averages, detrending and kriging in practice 01:30 – Using external data like magnetics and structure with kriging 02:09 – Common pitfalls: edge effects, over-smoothing and stationarity 05:14 – Letting geological structure guide smoothing 05:17 – A worked example using folded geology and copper grades 06:11 – Where CNNs fit, and how they compare to traditional geostatistics 07:28 – Tools and software for convolution, kriging and CNN workflows 09:05 – When not to use moving averages or CNNs 10:39 – Practical sanity checks after detrending 11:05 – A clear framework for combining geostatistics and machine learning If you work in resource estimation, geostatistics, or applied geology, this episode is packed with practical insights you can take straight back to your own workflows. 👍 If you enjoyed this episode, please Subscribe for more mining-focused technical discussions across the mine value chain, from out global consulting team.
