【摘要】 本文着重介绍了主要覆盖类型及覆盖区找矿当前所面临的各种挑战,提出通过定量预测评价来科学指导覆盖区找矿,从而降低不确定性及勘查风险。在此基础上,进一步讨论了覆盖区成矿-勘查系统研究、找矿-预测模型建立、弱矿化信息识别提取等关键问题,阐述了地质异常、非线性模型等方法技术应用于覆盖区矿产定量预测评价中的实际效果。更多还原

【Abstract】 In this paper,authors introduced the main types and the challenges of mineral exploration in covered areas,advocated mineral resources quantitative assessment of exploring for buried mineral deposits,and reducing grade uncertainty and risks in mineral exploration in covered areas.Then,some key problems,such as ore-forming and exploring systems,ore-finding and predicting models,and week anomalies caused by buried sources,have been discussed.It is shown that geological anomalies and nonlinear models can be applied to covered mineral deposits prediction.更多还原
