Abstract

According to previous studies, the use of enrichment factors in environmental studies is inconsistent with its original concept and that such indiscriminate use of enrichment factors should be stopped. In this contribution, it is shown through spatial correlation analysis that using enrichment factors is no better than using log-ratios of geochemical data for mapping of deposit-related anomalies.
