| 摘 要： | 西藏拉诺玛铅锌多金属矿床位于三江并流地段,矿床赋存于下三叠统波里拉组(T3b)灰岩中,通过研究该矿区地质背景,认为拉诺玛矿床受控于澜沧江自南西向北东逆冲推覆构造及复式背向斜褶皱.根据该区地层微量元素含量数据分析结果,以及地质背景和相关化探异常资料,确定波里拉组(T3b)为主要含矿层位,矿体多赋存于该地层南北向构造破碎带... |

| Abstract: | Tibet La Nuoma lead-zinc polymetallic deposit located in Three Rivers location,deposits occur in the limestone from Bolila Group(T3b) of Lower Triassic in layered or bandedshape,by studying the geological background,that La Nuoma deposit is controlled by the SW-NE thrust structure and double back on oblique folds.Based on the REE data analysis,and geological background information and related geochemical anomalies,and ultimately determine the Bolila Group(T3b) as the main ore body occurring in the multi-strata in the north-south tectonic fracture zone.Research and analysis show lead and zinc district vision of antimony ore mineral resources are considerable,delineated five exploration prospect areas. |
| Keywords: | La Nuoma lead-zinc polymetallic deposit geological features exploration prospect areas the Qamdo Basin Tibet |
