Abstract

Most of the clinopyroxene in the clinopyroxene skarn that contains the 4D copper orebody of the Shinyama ore deposit (Japan) was altered to amphibole owing to late-stage decrease of temperature. Two amphibole species are found: Ca-amphibole and cummingtonite-grunerite; the latter is rarely found in skarn-type ore deposits. In exoskarns derived from limestone, the following zonal arrangement is observed from the limestone to the igneous rock: cummingtonite-grunerite skarn, Ca-amphibole skarn, (clinopyroxene skarn), and garnet skarn. This arrangement is attributable to the increase in the chemical potential of CO//2 toward the limestone.
