营口东部区是我国硼矿重要产区之一。硼矿体主要赋存于晚元古代辽河群里尔峪岩组的下部，受层位控制。含硼蚀变岩带长１４ｋｍ，宽８～６９ｍ，硼矿体产于蚀变岩带中下部的镁橄岩中。背形向斜、向形背斜核部是硼矿富矿体成矿最有利地段，古浅海含硼碳酸岩凹陷盆地中心是硼矿成矿的最佳古地理环境。背形向斜、向形背斜核部的含硼镁橄岩是硼矿体及隐伏硼矿体的主要找矿部位。
The eastern part of Yingkou is one of the important boron-producing areas in China. Boron ore bodies mainly occur in the lower part of the Liluyu Formation of the Liaohe Group in the Late Proterozoic and are controlled by horizon. The boron-bearing alteration rock zone is 14 km long and 8 ~ 69 m wide. Boron ore bodies are produced in the mafirite in the middle and lower part of the altered rock zone. Back-syncline, anticlinal core is the most favorable site for the ore-rich boron ore body, and the center of the paleo-shallow borax carbonate basin is the best paleogeographic environment for boron mineralization. Borax-druse in the back-syncline and anticlinal core is the main ore-prospecting site for boron ore bodies and buried boron ore bodies.
