覆盖区成矿预测方法探讨——以蚌埠地区金矿预测为例

A PRELIMINARY STUDY ON METALLOGENIC PROGNOSIS IN COVERED REGIONS ——TAKING PROGNOSIS OF THE GOLD FIELDS IN BANGBU AREA AS EXAMPLE

本文以蚌埠地区金矿资源预测为例,探讨了覆盖区及半覆盖区矿产预测的途径和方法。指出,地球物理、地球化学、遥感地质等多种信息的综合解译和与矿产地质信息的有机关联,是揭示隐伏矿成矿规律的重要手段;采用“矿产二次预测方法”通过大区矿产预测模型向预测区逐步扩散,建立起本区统计预测模型,是在覆盖区开展模式类比预测的可行途径。文中讨论的成矿预测方法在安徽省蚌埠地区金矿预测中取得了较好效果,对我国中西部地矿产地质研究程度不高地区的成矿预测,具有普遍参考意义。

The autbors took the progrosis of gold resources in the Baagbu area as an example and made a preliminary study on the way of metallogenic prognosis in covered or half-covered regions. The authors hold that the comprehensive interpretation and correlation of geological, geophysical, geochemical and remote sensing information are major means to discover the minerogenic laws of blind deposits.It is efficient way for predicting mineral resources by contrasting with models in covered regions that through adoption of 'Two times prognostic deposits' method, local statistical prognostic model is set up by diffusing of prognostic model from region to the work area step by step.The method discussed in the paper has good effects in predicting gold fields in the Bangbu area, Anhui province and is also generally significance in predicting other ore deposits in the western central regions where no thorough investigation is carried out.
