| Abstract: | The data acquisition techniques for CEMP in mountainous areas of western China have specific problems comparing with other regions. For instance, the routine methods are usually difficult to be used and/or the quality of acquired data can not be ensured. We make comparison analyses to some problems on the basis of experiments porformed in recent years. These are concerning with how to choose electrode spacing in a flexible manner, how to control record time, what is the effect of measarement sites on data quality, the density of megnetic stations and effect of remote and near references. We summarize the characteristics of implication for CEMP in mountain areas of western China and emphasize the importance of study on the data acquisition techniques for CEMP in these areas. |
