  • Chondrodite form the Wondong mine, Korea, which is the first occurrence from the southern Korea, has been studied for its mineralogical characterization. It occurs in close association with penninite, phlogopite, diopside and garnet within the magnetite ore bodies, which are debeloped along the contact of the Hwajeol Formation and rhyolite. Two kinds of chondrodites are recognized by their different optical properties; the high birefringent untwinned one and the low birefringent twinned one. The former has slightly higher Mn content than the latter. Twinning in chondrodite has been formed in close relation to substitution Mg (Fe, Mn) in the humite solid solution, as evidenced by the chemical variation across the twin lamallae.

  • The Commission on New Minerals and Mineral Names (hereafter abbreviated as CNMMN) of the International Mineralogical Association was established in 1959 for the purpose of controlling mineral nomenclature, All proposals for introducing new minerals, changing mineralogical nomenclature, and discrediting or redefining existing minerals and mineral names should be submitted to the CNMMN for approval before publication. If approval is withheld, the proposal should not be published. This report incorporates material from previous reports on mineral nomenclature and procedures of the CNMMN (Fleischer, 1970; Donnay and Fleischer, 1970; Embrey and Hey, 1970; Hey and Gottardi, 1980; and Mandarino et al., 1984), and represents an attempt to consolidate this information and to present a there are differences between this report and the earlier ones, this versionis to be regarded as the correct one.
