Abstract
Natunal resources development starts from resources prospecting. Resources prospecting and engineering geological survey have so many common grounds as to their technique and object that the two fields should coopeate more closely. Among the techniques and knowledges employed in the engineering geological survey, the following may be of particular importance to resources prospecting, that is, seismic survey, numerical analysis of fault and fracture-systems based on rock mechanics, knowledge of rock mass classification and groundwater hydrology. On the contrary, application of the resources prospecting techniques to engineering geological survey may be most useful in surface and underground geological survey, geophysical and geochemical surveys, drilling, alteration survey etc. Because of the growing trend of larger scale civil engineering construction these days, undergroung geologic data such as those required in mining geology are becoming more and more important in engineering geological survey. In view of the close relationship between the above two fields of the applied geology, it is desirable for young geologists working in either field to have experience of the counter field as much as possible. In case of being employed in either of both fields surveying for the earth, the systematic action of environmental assessment including global emvironmental problem is important.
