A geologic profile expresses the geological feature situation in its location clearly and makes the problem on the geological feature clear. It has to be made by considering the topography condition of the place that the stratum was accumulated, sedimentary environment and the sedimentary age. A study of an Alluvium deposit substantially develops from three sides: a decision in a sedimentary age, presumption of sedimentary environment and introduction of a sedimentary facies analysis in recent years. A geologic profile has to be made so that formative process of the ground may be indicated based on recent research achievements about an Alluvium deposit.
