| 中文摘要: |
| 海南石碌矿区是以铁钴铜矿为主的超大型多金属矿集区，矿床成因类型为多因复成的火山热液沉积-变质型。本文在前人工作的基础上，提出了新的深部找矿思路，通过大比例尺地质填图、地球物理解译、区域旋转构造应力场分析、槽探及钻探等多种勘查方法和手段，在石碌矿区北部发现了三棱山向斜构造，并在向斜的槽部证实存在厚度大、品位高的铁矿体，实现了深部找矿的新突破。本文从地质背景、成矿类型、矿石成分、围岩特征及结构构造等方面，研究了该矿体的地质特征，探讨了矿体的成因类型，控矿因素等。指出了今后在石碌矿区寻找深部隐伏矿的方向。 |
| 英文摘要: |
| The Shilu mining field in Hainan Province, a super-large polymetallic ore concentration area domi-nated by iron, cobalt and copper, features a volcano-sedimentary-metamorphic deposit influenced by multiple min.eralization events. Building on previous research progresses, this study introduces a novel deep mining explorationapproach. Through large-scale geological mapping, geophysical data interpretation, stress field analysis of regionaltectonic rotation, trenching and drilling, we discerned a large syncline structure, namely the Sanlengshan syncline,in the northern part of the Shilu mining field. Large thicknesses of high-grade iron orebodies were found within thesyncline trough, marking a breakthrough in deep mining prospect. This study explores the geological characteristicsof orebody, including its tectonic setting, genetic type, ore composition, wall-rock characteristics and structural fea.tures. The genesis and ore-controlling factors are also examined. The study yields a guidance for future deep miningprospect of concealed ore deposits in the Shilu mining field. |
