| 摘 要： | 辽东硼镁石型硼矿床赋存于早元古宙富铁、硼火山沉积岩建造中，表现出明显的地层岩性控矿性。硼的成矿作用是多期的，沉积成矿作用是基础，变质成矿作用对原始沉积矿床起了改造和富集作用，构造变形作用使硼矿体发生了重就位。硼矿床的硼质来源以火山源为主，陆源为次，矿床成因属叠生层控变质火山沉积矿床。

| Abstract: | Szaibelyite-type boron deposits in East Liaoning occurred in Early Proterozoic iron-andboron-rich volcanic sedimentary formations, indicating an obvious ore-controlling characte-ristics of stratigraphic lithology. The mineralization of boron was multiphase: first, sedi-mentary mineralizition; second, metamorphic mineralization enriching and remaking theoriginal sedimentary deposits; at last, structural deformation reemplacing the boron ore bod-ies. Boron mainly stemes from volcanic source, land souce secondly. The boron depositswere of diplogenetic strata-bound metamorphic volcanic sedimentary deposits. |
