摘要
本文以砖庙硼矿区为例，依据矿床地质特征，矿床地球化学，Ｏ、Ｃ、Ｂ同位素特征，运用数学地质方法对辽东─吉南早元古宙硼矿床的矿床成因等问题进行探讨。认为研究区硼矿床可分为两个主要成矿期。矿床成因类型为沉积变质再造型。
As an example of Zhuanmiao boron mine,on the bases of the characteristics of depositgeology,mathematical geology,and the data on geochemistry of O,C,B isotopes,the paperdiscussed the genesis of Early Proterozoic boron deposit from E. Liaoning to S.Jilin and con-sidered the boron deposit in the studied area can be divided into two major metallogenicstages and it belonged to sedimentary-metamorphic reconstruction-type boron deposit.
