Chlorite geochemical vectoring of ore bodies: a natural kind clustering approach
Frontiers in Earth Science, 2023 Chlorite has long been considered a mineral group likely to have different trace element chemistry with proximity to mineralization, and therefore can be used to vector towards ore bodies.

How to make porphyry copper deposits
, 2020 Much of the world's economic copper resources are hosted in porphyry copper deposits (PCDs), shallow level magmatic intrusions associated mostly with thick ( > 45 km ) magmatic arcs, such as mature island arcs and continental arcs. However, a well-known,
