保加利亚科学家提出一种可定量评价地球化学找矿方法效益的公式系统。要求使用以下9个指数:1.样品数量;2.确定出的和检验过的异常数量;3.已查明的矿化现象,包括有工业价值的矿化现象;4.进行过地球化学测量的面积,包括含矿面积(查明异常的面积数);5.包括以下要素的修正系统:a.经济效益,b.每吨储量价格,c.用于地球化学找矿的开支;6.综合修正系数;7.查明的含矿区和矿种数;8.储量和远景资源量;9.包含储量和远景资源
Bulgarian scientists propose a formula system that can quantitatively evaluate the benefits of geochemical prospecting methods. The following nine indices are required: 1. Number of samples; 2. Number of identified and tested anomalies; 3. Mineralization identified, including mineralization of industrial value; 4. Geochemical measurements (Including the area of anomaly detected); 5. A correction system that includes the following elements: a. Economic benefits, b. Price per ton of reserves, c. Expenditures for geochemical prospecting; Comprehensive correction coefficient; 7. identified ore-bearing areas and mineral resources; 8. reserve and long-term resources; 9. contain reserves and long-term resources
