THEORETICAL MODEL OF SHORT RANGE TERRAIN CORRECTION OF GRAVITY EXPLORATION

Generally based on surveys of typical geological section,it can be determined that if the short range terrain correction of gravity exploration is necessary or not.And the numerical values of terrain correction can be obtained by simple terrain correction instrument.But the surveys of typical section are hard to be all right and the cost is high.After calculation of physical models and statisties of a quantity of determined numerical values,the author proposed a series of parameters as well as a simple and low costed method of short range terrain correction.
