云南省大理马厂箐-宾川小龙潭整装勘查区化探数据处理方法研究

化探是地质找矿的重要方法，在一定程度上决定着地质找矿的成败。本文通过对云南大理马厂箐-宾川小龙潭整装勘查区1:5万水系沉积物测量数据采用不同处理方法进行对比研究，得出比用传统的数据处理方法确定背景与异常，用衬值方法成图既能够达到地球化学图信息足够丰富并且能够较好的反映研究区的低缓异常，也能使较大的异常被拆分成若干小异常，使这些异常与已知的矿床（段）对应更好，以达到缩小靶区的目的，同时弱缓异常得到很好的增强，局部圈出若干个新异常，对实现找矿突破有一定的意义。

Geochemical data processing methods for the integrated exploration area in Machangjing, Dali -Xiaolongtan, Binchuan, Yunnan Province

Geochemical exploration is an important method of geological prospecting. It determines the success or failure of geological prospecting to a certain extent. In this article, the authors use different methods to process the 1: 50,000 data of steam sediments in the integrated exploration area in Machangjing, Dali - Xiaolongtan, Binchuan, Yunnan Province. In comparison with the traditional methods that determine background and anomalies, the contrast map method can not only make the geochemical map show more information and reflect the low-gentle anomalies better, but also make the large anomalies be split into several small ones and correspond to the known deposits in order to achieve the goal of narrowing the target area and enhance the gentle anomalies. Meanwhile, it can delineate new local anomalies which are of some significance to the breakthrough of prospecting.
