The types of gold deposit in the Chinkuashih area can roughly be divided into three types: pure gold, gold mixed with copper, and surface gold. The causes of the vein formations, the gold content, and the distribution of veins are different in each type.
除了金礦的形成，金瓜石地區的礦體還可以大分成金礦礦脈、金銅礦礦筒、金包等三種，每一種的成因、黃金含量、礦脈分佈也都不同。
