提锰矿是目前中国紧缺矿产，依据全国矿产资源潜力评价数据和成果，对全国锰矿资源进行了现状分析和潜力预测。中国锰矿形成的主要大地构造部位包括：”①大陆边缘浅海；②台内裂陷带(如华北地台之燕辽沉降带)；③造山带中裂陷海槽等。中国锰矿以泛扬子周边地区最为发育，桂西南、湘黔渝为主要富集区。中国锰矿床的古地理展布表明，具有重大工业价值的锰矿床均形成于海相环境中，并主要为碳酸锰矿床。今后具有找矿潜力的锰矿类型主要有：海相沉积型和风化壳型，另外，海相火山岩型和陆相沉积型也有一定的潜力。依据大地构造背景与成锰盆地性质之间的关系，将中国锰矿划分为10个Ⅲ级成矿带，14个成矿远景区，对其主要含锰层位、成矿特征、主攻类型、资源潜力进行了分析，提出了重点找矿部署区建议，可为国家锰矿找矿突破提供支持。
提錳礦是目前中國緊缺礦產，依據全國礦產資源潛力評價數據和成果，對全國錳礦資源進行瞭現狀分析和潛力預測。中國錳礦形成的主要大地構造部位包括：”①大陸邊緣淺海；②檯內裂陷帶(如華北地檯之燕遼沉降帶)；③造山帶中裂陷海槽等。中國錳礦以汎颺子週邊地區最為髮育，桂西南、湘黔渝為主要富集區。中國錳礦床的古地理展佈錶明，具有重大工業價值的錳礦床均形成于海相環境中，併主要為碳痠錳礦床。今後具有找礦潛力的錳礦類型主要有：海相沉積型和風化殼型，另外，海相火山巖型和陸相沉積型也有一定的潛力。依據大地構造揹景與成錳盆地性質之間的關繫，將中國錳礦劃分為10箇Ⅲ級成礦帶，14箇成礦遠景區，對其主要含錳層位、成礦特徵、主攻類型、資源潛力進行瞭分析，提齣瞭重點找礦部署區建議，可為國傢錳礦找礦突破提供支持。

Manganese is an important metal which is in serious shortage in China at present. Based on dataset and achievements of national mineral resources assessment project, the authors made current situation analysis and potential prediction for manganese resources in China. The main ore-forming geotectonic positions of Mn in China are located in such areas as shallow sea near continental margin, chasmic belt (subsidence zone of Hebei-Liaoning), and marine depression in the orogenic belt. Mn deposits are developed mainly around Yangtze region in China. The ore concentration areas of Mn lies in southwest Guangxi, Hunan, Guizhou and Chongqing. The study of paleogeography of Mn deposits in China shows that most important Mn deposits with high industrial value formed in marine environment, mostly Mn carbonate. Mn deposits with tremendous resource potential in China lie in marine sediments and weathering crusts;in addition, marine volcanic and continental sediments also have some resource potential. According to relations between tectonic structures and ore-forming basins of Mn, ten three-level metallogenic zones and 14 metallogenic prospective areas were delineated. The ore-forming rocks, metallogenic features, main types, and resources potential were analyzed. Suggestions on key prospect deploy areas were made for support of national Mn prospecting breakthrough.
