武当-桐柏-大别成矿带是我国最为重要的金红石成矿区带和原生金红石主要产地之一。本文根据近期对该成矿带金红石矿床开展的野外地质调查和室内整理研究工作,综述了武当-桐柏-大别成矿带金红石矿床的地质特征,将成矿带内金红石矿床(点)划分为区域(沉积)变质型、榴辉(闪)岩型和机械-沉积型三种类型。同时从地层、构造以及成矿地质条件等方面简要探讨了矿床(点)的成矿规律和控矿因素,在此基础上识别出地层时代、岩性、地球化学异常等找矿标志,并初步勾勒出湖北枣阳-河南新县以及湖北英山-安徽潜山两个金红石矿床的找矿远景区。本文对成矿区金红石矿成矿规律的总结和成矿条件的分析显示出成矿带金红石具有极大的找矿潜力,可望成为我国最具潜力的金红石战略储备基地。
武噹-桐柏-大彆成礦帶是我國最為重要的金紅石成礦區帶和原生金紅石主要產地之一。本文根據近期對該成礦帶金紅石礦床開展的野外地質調查和室內整理研究工作,綜述瞭武噹-桐柏-大彆成礦帶金紅石礦床的地質特徵,將成礦帶內金紅石礦床(點)劃分為區域(沉積)變質型、榴輝(閃)巖型和機械-沉積型三種類型。同時從地層、構造以及成礦地質條件等方麵簡要探討瞭礦床(點)的成礦規律和控礦因素,在此基礎上識彆齣地層時代、巖性、地毬化學異常等找礦標誌,併初步勾勒齣湖北棘暘-河南新縣以及湖北英山-安徽潛山兩箇金紅石礦床的找礦遠景區。本文對成礦區金紅石礦成礦規律的總結和成礦條件的分析顯示齣成礦帶金紅石具有極大的找礦潛力,可望成為我國最具潛力的金紅石戰略儲備基地。

The Wudang-Tongbai-Dabie Metallogenic Belt (WTDMB) is one of the most important rutile metallo-genic provinces and natural rutile habitat in China. In this study, according to the field geological survey and doc-umented studies for the typical rutile ore deposits in the belt, geological features of the rutile deposits in the WT-DMB is reviewed. These deposits can be classified into regional (sedimentary) metamorphic-, ecologitic- (gar-netiferous amphibolitic-) and mechanical depositional type. Meanwhile, we briefly discuss the metallogenic regu-larities and ore-controlling conditions of the ore deposits from the aspects of strata, structure and metallogenic ge-ological feature. Based on such discussions, it is proposed to figure out prospecting indicators of stratigraphic age, lithology and geochemical anomaly, as well as two prospecting areas of Hubei Zaoyang-Henan Xinxian and Hubei Yingshan-Anhui Qianshan from the metallogenic belt. Our studies on the metallogenic conditions and regularities of these rutile deposits suggest that the WTDMB has great prospecting potential and is likely to be the most poten-tial strategic reserve base in China.
