Abstract:Abstract. The analysis of hydrothermal alteration in exploration
drill cores allows for fluid–rock interaction processes to be traced, for fluid
flow paths to be identified, and thus for vectors in mineral systems to be determined. Hyperspectral
imaging techniques are increasingly being employed to fill the scale gap
between lab-based petrographic or geochemical analyses and the typical size
of exploration targets. Hyperspectral imaging permits the rapid,
cost-efficient, and continuous characterisation of alte… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
