THE PRINCIPLE OF GEOCHEMICAL ANOMALY DELINEATION BASED ON THREE DIMENSIONAL GEOCHEMICAL EXPLORATION DATA METHOD AND ITS SIGNIFICANCE
-
摘要: 以往传统的化探异常圈定，均采用二维化探数据计算方法，这种数据处理方法在勘查地球化学行业已应用多年，到目前为止也仍然是生产中勘查地球化学规范执行标准。但在采样和景观差异较大的前提下，这种数据处理方法在找矿方面尚有不足之处。为弥补这些不足，我们提出了一种新的化探数据处理方法，即增加高程要素的三维数据处理成图方法。通过试验证明该方法对综合异常的圈定效果较好，异常物质流向更为清楚。三维数据处理法圈定的范围小、浓集中心明显，有利于准确布置地表探矿工程，并可以节约勘查成本，提高找矿命中率。在地球化学环境分析和地球化学找矿评价方面具有重要的现实意义。

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. -
