| The Classification Of Iron Ore Types And Metallogenic Series In Kangdian Massif With Reference To Their Characteristics |

| Abstract:The iron deposits in the Kangdian massif are mainly of stratabound type, bearing such characteristics as time and rock control, polycycle, multi-source mineralization and inheritance. The iron deposits in Dahongshan Group, Heitoushan Formation, Dalongkou Formation, Yinmin Formation and Dayingpan Formation account for 95.69 percent of the total iron reserves within the broad-sense Kunyang Group in the Yunnan segment of this massif, while the Panzhihua type V-Ti magnetite deposits controlled by Hercynain stratabound melacomplexes make up.98.84% of the total iron potential in Sichuan Province. Seventeen ferriferous beds have been recognized in strata from Lower Proterozoic Ailaoshan Group to Middle Proterozoic Dahongshan Group (Hekou Group, Yanbian Group and Ebian Group), Longchuan Group and Kunyang Group (Huili Group and Dengyangying Group). The iron deposits are divided into six major genetic types, i. e., sedimentary-metamorphic type, supergene hydrothermal type, skarn type, magmatic type, volcanic type and weathering-leaching type, and also into seven major metallogenic series. Relatively detailed description has been made in this paper for characteristics of four most important metallogenic series. |
