Epithermal Ore Deposits Associated With Tertiary Volcanism—And the Feasibility of Metal Detecting for Them
December 2000
Epithermal ore deposits are common in regions of late volcanic activity, especially areas associated with Miocene and later Pliocene extrusive volcanics that have not been deeply eroded since the ore was deposited. Many are simple fissure veins, but stock-works and ore-pipes are also common.
