Gold and silver deposits can be found in geologic settings such as volcanic regions, hydrothermal veins, and sedimentary rocks. These deposits are often associated with tectonic plate boundaries and areas of past volcanic activity.
Metallic deposits (gold) in the Philippines are typically found in igneous-related structures such as porphyry copper deposits, epithermal gold-silver deposits, and skarn deposits. These deposits are often associated with volcanic arcs and subduction zones due to the geologic processes that occur in these tectonic settings. The presence of faults, fractures, and magmatic intrusions in these areas can create pathways for mineral-rich fluids to concentrate and form metallic deposits like gold.
