Abstract: Abstract The source(s) of lode gold deposits formed in Precambrian cratons related to accretion/collision and cratonic reactivation, formerly attributed to either supercrustal volcano-sedimentary sequences or deep crustal/sub-crustal origin, remain controversial largely because gold deposits are… read more here.

DOI: 10.1073/pnas.2116380119
Abstract: Significance There is a common consensus that lode gold deposits mostly precipitated from metamorphic fluids via fluid boiling and/or fluid–rock interaction, but whether magmatic hydrothermal fluids and the mixing of such fluids with an external… read more here.

DOI: 10.15446/esrj.v24n3.80653
Abstract: The shear zone hosted lode gold type deposits are located at the northeast part of Antioquia department of Colombia. The characteristics of ore-forming fluids were discussed using fluid inclusion petrography and microthermometry analysis. Two stages,… read more here.
