Abstract

The polymetallic -1590 Ma Abra deposit is hosted within 1680-1450 Ma sediments and is concealed under thick weathered regolith. The deposit was investigated as a natural laboratory to define the size and geometry of multi-scale footprints associated with mineral systems. Deep crustal-scale basement structures beneath the deposit form a triple-junction that is overlain by a vertically zoned mineral footprint containing white mica, chlorite and carbonate. Hydrothermally altered overlying sediments indicate that deposit formed through sub-seafloor replacement. The mineral footprint of the deposit has been preserved through weathering and was mapped at the surface from ground-truthed remote sensing data.
