内生硼镁石矿床大部分分布在辽东一带,其中砖庙硼镁石矿床是较大的一个。该矿床经过六年地质勘探工作,获得了许多宝贵资料;一九七七年始,进行了近三年时间的补充勘探工作,又取得了一些新成果。关于内生硼矿床的一些基本问题,如硼矿地质、矿床形成条件、矿床成因问题,一直存在三种不同观点: Most of the endogenous boehmite deposits are located in the Liaodong area, among which the brick magnesia deposit is the larger one. After six years of geological prospecting work, the deposit has gained a lot of valuable information. Since the beginning of 1977, the exploration has been completed for nearly three years and some new achievements have been made. There are three different points of view regarding some basic issues of endogenous boron deposits, such as boron geology, deposit formation conditions, and genesis of the deposit.
