摘　　要：利用地球化学块体理论进行矿产资源评价的资源量预测工作中,大多是基于地球化学数据本身,虽考虑了除成矿物源之外的如地层、构造等地质背景因素的影响,但仅限于定性阶段,多用于地球化学块体含矿性的分析及远景区的分级.在充分研究地质背景因素的基础上,认为如地层、构造等富集因素与成矿物质基础是矿床形成的2个必要条件,因此,在资源量计算的工作中,还应考虑富集因素的影响,据此建立了找矿概率-地球化学块体法,并将其应用于辽东硼资源量的定量评价中.结果表明,辽东地区硼矿资源潜力较大并符合客观实际.At present, researchers use the geochemical block theory to predict amount of mineral resources based on the geochemical data. Although they take the influences of formation and structure besides the ore material source into account, the application remains in qualitative stage, such as the analysis of the ore potentiality of geochemical block and the classification to prospective area. On the foundation of geological background researches we come to the conclusion that the enrichment factors, namely formation and structure are two necessary conditions for the ore-forming material base. So in the course of calculation of resource extent, we should take their influences into consideration. Finally, we set up the ore prospecting probability-geochemical block ore prospecting method, and use it to quantitatively assess the amount of boron ore in eastern Liaoning. Results show that the eastern Liaoning is of great potential in boron ore, which accords with the facts.
