  • In Korea, it is reported that the study about tourism geology, which is a new branch af applied geology that would support the growth of ecotourism world-wide, is significantly deficient. The objectives of this study include (1) the promotion in geodiversity of tourism geology using the data for type and distribution patterns of geological and geomorphological landscapes resources, and (2) the redoubling of diversity in environmental interpretation programs offerend by National Parks Authority (NPA). According to this research results, 62 geological and geomorphological landscape resources in Naejangsan national park were observed. Weathering topography is the most discovered type followed by river, mountain and tectonic topography in decreasing order. It is thought that the above-mentioned data can be utilized to sort and filter by the discussion through consortium organized by geologist and geomorphologist. Furthermore, in order to promote the activation of developing user-oriented geotourism sites, the monitoring on demographical characteristics of geotourists, behaviora characteristics of geotourists within geotourism site, and the analysis for developing geotourism program and events should be accompanied. And, the support of geological engineering dealing the estimation of weathering degree and development of conservation techniques for the object of geotourism will improve the activation of tourism geology.

  • Magnetic method is rapid, cheap and simple geophysical exploration technique, and has wide range of applications such as resources prospecting, geological structure investigation and even geotechnical and environmental problems. Especially, aeromagnetics gives fundamental and useful geoscientific data fnr not only assessment of potential resources, but also national land planning. Magnetic method, perhaps the oldest geophysical technique, was relatively early introduced into Korea. Documents during Japanese occupation says that magnetic method was used for exploring metallic ore deposits and hot spring, and that a geomagnetic observatory was operated. From mid 1950's, after Korean War, magnetic explorations for natural resources such as metallic ore, uranium, coal, and groundwater were intensively executed for industrialization. Apache aeromagnetic survey project during $1958{\sim}1959$ and its ground follow-up surveys are typical and important cases in those days. Magnetic survey techniques were rapidly advanced during 1970's and 1980's with improvements of instruments, growth of geophysical manpower, and availability of computers. The national aeromagnetic mapping project by KIGAM in 1981 showed the improved technical capability of those days. Decline of mining industry since mid 1980's moved the exploration objects from traditional resources to new ones such as groundwater and geothermal resources, and applications to investigation of geological structure were revived. Recently appeared applications such as natural hazard assessment, and engineering and environmental studies increased the magnetic method's utility in the realm of exploration.

  • Mineral wastes are generated by the minerals, mining, and metal industries. These are generally inorganic waste streams of mainly waste rock or residues from refining during extraction of metals or minerals from the ore. There are many plants where minerals are recovered in secondany circuits, treating tailings, where the feed grades are much lower than would be economic on a mined ore. The world is now becoming aware of the finite nature of its resources at a price, and of the ever-increasing development costs of large new mines. Reprocessing of old tailings on a large scale must be worth examining very seriously by those with access to sufficient material of this type. In the present paper, mineral separation techniques to recover valuable metals and resources from the old tailings are reviewed, and new trends for future developments are also discussed.
