Abstract
|
|
|
This study is to characterize the occurrence types and mineralogical characteristics of asbestos for the Kwangcheon areas, Chungnam. The mine areas had been exploited as asbestos mines for several decades since 1930. Host rocks of the asbestos are serpentinites and altered rocks of the ultramafic rocks. Representative samples of the host rocks and minerals were sampled and were examined with microscopes. To confirm for the existences and compositions of the asbestos, the rock samples were analysed with EPMA, XRD and EDS. Chrysotile, tremolite and actinolite were found as asbestos and non-asbestos forms in these areas. Chrysotiles, as nonasbestos forms, occur in the host rocks with mesh and hourglass textures. They, as asbestos forms, are mainly found as the veins. The tremolite and actinolite, as asbestos types, occur as alteration products of the olivine and pyroxene within the host rocks. They, as asbestos types, are also found following the cracks and fractures. Overall results suggest that three types of the asbestos are found in the Kwangcheon and Kaewol mine areas. Based on the occurrence types for the asbestos, additional studies are required
for the asbestos in the top soil and air.
