辽东—吉南地区下元古界含硼岩系的厘定

Definition of Boron-Bearing rock series of lower proterozoic erathem in eastern Liaoning and southern Jilin

辽东—吉南地区下元古界产有丰富的硼矿资源,半个多世纪以来几乎所有硼矿地质勘查报告、有关论文、专著等无不涉及含硼岩系。含硼岩系称谓比较混乱,有"下元古界含硼岩系"、"宽甸群含硼岩系"、"集安群含硼岩系"、"辽河群里尔峪组含硼岩系"、"辽东岩群含硼岩系"以及"含硼层含硼岩系"等多种称谓。通过编纂《中国矿产地质志·硼矿卷》,对辽吉硼矿进行了新一轮研究,摒弃了过去多种称谓的乱象,厘定集安群新开河组为含硼岩系。

There are lots of boron resources in Lower Proterozoic Erathem of eastern Liaoning and southern Jilin.For more than half a century,almost all of geological survey reports,papers and monographs on boron deposits are based on the boron-bearing rock series from there.Appellations of boron-bearing rock series are confused,such as“boron-bearing rock series of Lower Proterozoic Erathem”,“boron-bearing rock series of Kuandian Group”,“boron-bearing rock series of Ji’an Group”,“boron-bearing rock series of Lieryu Formation in Liaohe Group”,“boron-bearing rock series of Liaodong Rock-group”and“boron-bearing rock series of Boron-bearing Layer”.Through writing the book of“Volume for Boron of Mineral Geology of China”,we make a new-round study on boron deposits in Liaoning and Jilin province.At last we define the Xinkaihe Formation in Ji’an Group as the boron-bearing rock series.
