经前期试验结果表明，在干旱荒漠景观区斑岩型铜矿勘查中，磁性组分测量具有较常规土壤测量更有效发现异常的能力，其实用性优势初现端倪。为进一步扩大磁性组分测量这一新技术的适用范围，同时也为了更进一步明确我国干旱荒漠景观区有色金属矿地球化学勘查方法，以新疆东天山铜镍硫化物矿为例，对磁性组分测量技术有效性进行试验研究。试验选择 EDA数据处理技术对两种测量数据进行处理分析，结果发现，与常规土壤相比，磁性组分测量技术除具有异常下限较高、异常点数更多等特点外，还突显出强化弱小异常、发现新异常等优势，充分体现了该技术在干旱荒漠景观区勘查中独特的优越性。

The preliminary test results show that in the dry desert landscape area,magnetic material survey is capable of discovering abnormal more effectively than soil,and its practical advantage has just shown.In order to expand the use range of this new technology,as well as to clear the geochemical exploration method of nonferrous metals prospect in the dry desert landscape area,this paper takes Cu-Ni sulfide deposit in east Tianshan for example and discusses the availability of magnetic material survey.Compared with the conventional soil survey,magnetic material survey has higher anomaly threshold and more outliers by EDA technology processing.This survey technology could strengthen the small and weak anomalies and find some new anomalies so that it has unique superiority in arid desert landscape area.
