摘　　要：硼是典型的亲石元素，在地壳中富集。在岩浆活动中，它是挥发性成分，对矿物结晶及成矿元素的运移和富集有重要影响，测定岩矿中硼的含量不仅可作为划分岩石类型的重要依据，也是判断成矿可能性的依据之一。过去由于受硼测试方法的限制，硼的地球化学研究工作受到一定的影响。Described in this paper are the optimum condition for direct [BF4]-electrode pote-ntial determination of trace boron in rocks and the separation and elimination of inter-ferring elements. In addition, the determination of sample standards and experiments an the recovery of sample standard+boron standard have been conducted. On these bases the procedure of determining trace boron in rocks has been established, as is des-cribed in the present paper. Repeated tests have shown that this method is reliable with a detection range of 0.000 X-X%. This method has the advantages of simplicity, stability, high accuracy and low cost.
