| Abstract: | Some "egg-like isolated hills" had been seen at the topographical chart. Views on. their grenesis varied. Sub-marine topographical and geomorphological study of the offshore Che-ngmai cape show that these isolated hills consist of basalt with basalt plain and wavy geo-morphological units formed by sphere-weathering basalt being developed around them. These isolated hills are yolcanic cone formed, during middle or late Pleistocene.These volcanic cones are not the typical ones because dimension of them were smaller and they were eroded by strong tidal current for long long time. |
