We have just completed our latest drillhole at Lubango. This is a drill into the Stimson sandstone, trying to characterise the silica-rich mineralogy: has it been derived from low temperature fluids after the rock has formed, or were high temperature silica grains brought in by winds as the sandstone was forming? CheMin XRD will help determine the answer as we can constrain the temperature from the identity of the minerals.
I will be Geo Science Theme lead for two sols this week and my colleague Dr Susanne Schwenzer will be joining me to get trained up for this operations role.
