化探趋势面分析中的若干问题——以云南澜沧铅锌矿区为例

Some Problems of Trend Surface Analysis Should be Considered in Geochemical Exploration-as Exempllfied by the Lancang Pb-Zn Ore Area, Yunnan

本文以云南澜沧矿区为例,就化探趋势面分析中原始数据的组合、不同分析方法所获数据的同时利用、异常下限值公式的选择及原始数据是否取对数等4个问题进行了探讨.

Taking the Lancang Pb-Zn Ore area as an example, in this paper following problems on trend surfase analysis in gecchemical exploration are discussed: 1. the combination of primary data, 2. How to make use the data collected simultanecusly by different analytical methcds?, 3. the selection of threshold of an anomaly, and 4. whether or not the primary data should be ploted on a logarithmic coordinate system?.
