Evaluating a biogeochemical mechanism for soil anomaly formation using diffusive thin-film samplers in geochemical exploration

期望能为金及贱金属的化探工作提供新的、有效的技术手段。该技术将采取以下形式：（i）增加对迁移覆盖层中土壤地球化学异常的地球化学形成的理解和新的概念模型;（ii）矿化区土壤和地下水的新化学分析技术。改进的异常形成模型将为在运输覆盖下的地形中进行勘探提供更清晰的框架。新的方法有可能提高异常探测埋藏矿化，特别是如果异常已形成地球化学。

We expect to develop new and effective technology for geochemical exploration for gold and base metals. This technology will take the form of: (i) increased understanding of, and a new conceptual model for, biogeochemical formation of soil geochemical anomalies in transported overburden; (ii) new chemical analysis techniques for soils and groundwater in mineralised areas. Improved models for anomaly formation will provide a clearer frame work for exploration in terrain under transported cover. New methodology has the potential to enhance anomaly detection for buried mineralisation, especially if the anomaly has formed biogeochemically.
