What geological processes enable gold particles to naturally cluster together like this? First of all, gold is mostly found in quartz veins in and around igneous intrusions. It happens with a very hot hydro-thermal fluid of silica, oxygen and concentrated gold that is created during incidences of compressional forces acting on the crust.
