摘要
During 1∶50 000 regional survey in Diaoluoshan area, Lingshui County, southeastern Hainan Province, the authors subdivided the regional stratigraphic system into five lithostratigraphic units through integrated study of stratigraphy. The petrological, deformation and kinematic features of deformable zone of newly discovered NE-trending Mangsan Reservior-Changfeng ductile shear zone are studied in detail. One rare earth deposit and ten ore occurrences are discovered in this geological survey, and four metallogenic prognosis areas are pointed out for further geologic prospecting. The types and distributing character of geological hazards are investigated, and the formation mechanism and inducement of which are also discussed.
