Abstract

Abstract

Two-dimensional geochemical data calculation method, as the traditional method in geochemical exploration anomaly delineation, has been used in the geochemical exploration industry for many years. However, this data processing method has some deficiencies in the prospecting and prospecting area in the premise of sampling and landscape differences. In order to compensate for these shortcomings, three-dimensional data processing and mapping method is proposed, which added elevation elements. It is proved by experiments that this method is better for comprehensive anomaly delineation and the abnormal material flows are clearer. The delineation range of the 3D data processing and mapping method is relatively small with obvious concentration center, which is conducive to the accurate arrangement of surface exploration engineering, saving prospecting cost and improving the accuracy of prospecting.
