  • As the spirit of reconciliation between the two Koreas ripens, the integration of mineral names is required in preparing the reunification between the South and North Koreas. Currently, mineral names in Korean do not adopt the guideline for romanization of Korean that was proposed by the National Institute of the Korean Language (NIKL), and different names are often used for an identical mineral species. Here, for mineral names in Korean, we suggest using (1) the suffix, "$s{\breve{o}}k$", both for metallic and non-metallic minerals, (2) names in the NIKL example-list if available, (3) the suffix "$s{\breve{o}}k$" for minerals whose names are based on the names of persons or localities.

  • The purpose of this study was to investigate high school students' interest on minerals and rocks. Seven hundred and eighty three students from four different regions (i.e., Seoul, Kyunggi, Chungbuk and Jeju) participated in this study. The results can be summarized as follows: (1) The students have somewhat low interest about minerals and rocks. In addition, the students lose the interest because they have been forced to learn minerals and rocks theoretically. (2) Girls' interest on minerals and rocks was higher than that of boys.

Formation of Alunite and Schwertmannite under Oxidized Condition and Its Implication for Environmental Geochemistry at Dalseong mine (산화환경하에서 명반석, 슈베르트마나이트의 형성특징과 환경지구화학적 의미: 달성광산)

  • Sulfates such as alunite and schwertmannite formed under oxidation condition play a important role in geochemical processes taken place at waste dumps and a creek from Dalseong mine, Daegu. Water chemistry shows pH decreases from upstream toward downstream creek, mainly due to formation of schwertmannite that is the most abundant phase along the creek. The removal of Al from the creek is preferentially attributed to formation of Al-bearing minerals and Al-sulphates. Among them, alunite is the most important Al-sink phase that occurs at higher pH than $pK_1$, Al hydrolysis constant. With high saturation index, alunite formed at the creek has a spherical form, commonly associated with schwertmannite. Secondary minerals formed on the surface of altered or weathered surfaces of heavy metals from the wasted dump that underwent severe oxidation, where alunite has characteristic habits which are spheric, radiating, and botrytis-like aggregates. Natroalunite occurs in association with alunite, or as mixtures of both of them. Because the pH decreases with distance due to formation of schwertmannite, although total contents of dissolved ions slowly lessen at least in the AMD, it is expected that the minerals precipitated at the creek can be exposed to subsequent dissolution, which may induce possible environmental problems.
