   As mentioned, the transition of colloform to crystalline structures is achieved mainly by the reversibility of gel to sol and possibly from sol to a solution phase out of which crystallization can take place.

   The colloform ores, developed primarily in the open spaces of breccias and fractures, are inferred to be younger than disseminated ores on the basis of the following textural relationships […]
