| 摘 要： | 鞍山-本溪地区是我国条带状铁矿重要成矿区,现已发现了众多大型、超大型铁矿床.在区域地质、地球物理资料的基础上,采用欧拉反褶积等重磁场处理解释技术,通过综合研究和三维地质建模,提出了3种深部铁矿发育模式,并对研究区进行了铁矿远景预测.预测在火连寨、思山岭、卧龙镇、南芬东、北台等6个地区可能存在逆冲推覆型及向斜覆盖型深部铁矿,在灯塔县西南张台子镇及鞍山西北部存在新生界覆盖型深部铁矿.进一步指出本溪火连寨逆冲断层下盘3km左右、本溪思山岭逆冲断层下盘2km左右、灯塔县张台子镇覆盖区下2km以浅存在含铁建造,铁矿找矿远景广阔.

| Abstract: | Anshan-Benxi area is the most important metallogenie site of banded iron formation in China, with numerous large and super large iron deposits. On the basis of regional geological and geophysical data, adopting the Euler deconvolution processing and gravity and magnetic inversion technique, three types of developing model for the deep iron deposits are put forward by an integrated study on three-dimensional geological modeling, with a prediction for iron ore prospect. It is predicted that the thrust nappe type and syncline covering type deep of iron deposits exist in Huolianzhai, Sishanling, Wolongzhen, east of Nanfen and Beitai. The Cenozoic covering type of deep deposits are expected in Zhangtaizizhen, southwest of Dengta County and northwestern Anshan. Furthermore, iron formations may exist about 3 km under the thrust fault in Huolianzhai of Benxi, about 2 km under the thrust fault in Sishanling of Benxi, and about 2 km under the covered area in Zhangtaizizhen of Dengta, with a great prospect. |
