湖北省1∶20万区域化探资料质量评估

Quality Assessment of 1∶200000 Regional Geochemical Exploration Data in Hubei Province

对湖北省已经完成的1∶20万区域化探资料按图幅进行质量评估,使区域化探资料更好地广泛应用于资源、环境评价和基础地质研究。评估的原则主要是工作方法技术正确性和分析数据精确性,元素空间分布规律与主要地质体吻合程度,元素异常分布与各类已知矿床吻合程度,提供新的找矿靶区并取得异常查证及找矿效果,提供的成矿规律成矿预测和基础地质研究地球化学信息等。以评估记分的方法对各图幅资料进行打分,按四个类别进行评价分类,最终提出了资料处理意见。

In order to make regional geochemical exploration data adaptable to the research of resource, environmental assessment and basic geology, the author assesses the quality of 1 ： 200000 regional geochemical exploration data by maps. The principles of assessment are listed as folows ： the accuracy of working methods and precision of analytical data, spatial distribution of element and the match condition of main geological bodies, abnormal distribution of element and the match condition of a variety of measured deposit, providing anomaly survey and prospecting results in pospecting targets as well as metallogenic regularity＆ prognosis and geochemical information of basic geological studies. According above-mentioned principles the author rates the classification of maps on scale of one to four.
