Hood, SB and Cracknell, MJ, Fluid flow interpretation in fossilised hydrothermal systems using vein measurements from underground photography, SEG 2017 Ore Deposits of Asia: China and Beyond Programme, 17-20 September 2017, Beijing, China (2017) [Non Refereed Conference Paper]
This research demonstrates automated vision-oriented pattern recognition methods that provide geologists with information useful for interpreting ore bodies without the direct supervision of a domain expert. Here we show that underground mining face photos from development drives from an Archean shear-hosted gold deposit can be rapidly analysed to produce models representing high fluid flux during ore deposit formation. Our findings add to the existing knowledge of hydraulic connectivity in such shear zones.
The ability to derive structural information and interpretations from underground photographs provides an opportunity to add value from an underutilised mining dataset. We anticipate our methodology will assist mine geologists to model geological features representing possible ore shoots, such as dense stockwork or breccia. Structural interpretations of ore deposits are commonly built by scaling manually recorded geometrical relationships from outcrop-scale upwards. Our approach also generates information from outcrop, but with an aim towards speed and objectivity. The resulting deposit-scale interpretations are intended to create an independent model of permeability to assist resource modeling and geological controls on ore shoot geometry.
