| 中文摘要: |
| 通过对西藏塔惹增地区尺阿弄铁铜矿床详细的地质构造背景、含矿岩石及产出特征等研究表明，尺阿弄铁铜矿床，形成于板块碰撞造山到青藏高原新生代板内造山的重大构造转折过程中，成矿期为晚白垩世，其与板块碰撞形成的花岗斑岩以及二叠系下拉组灰岩关系密切，依此把测区内尺阿弄铁铜矿床确定为矽卡岩型矿床。尺阿弄矽卡岩型铁铜矿床的确定，表明冈底斯成矿带不仅有斑岩型矿床，亦有矽卡岩型矿床，对冈底斯成矿带成矿类型多元化及对在该成矿带内寻找同类型矿床提供了新的资料。 |

| By study the geological tectonic background and ore-bearing rock occurrence characteristics of Chianong copper-iron deposit, showed that it formed in the process of significant tectonic transition of plate subduction and collision epeirogeny to the Cenozoic intraplate orogeny in survey area. Metallogenic epoch was the late Cretaceous.It was closed with the granite porphyry formed in the plates collision and the limestone of Xiala formation in Permian.In which Chianong copper-iron deposit in the survey area get identified as skarn deposits.The determination of skarn type copper-iron deposit in Chianong，improved not only the porphyry type but also the skarn type deposit being in Gangdese metallogenic belt. It provides new data for metallogenic types diversification in Gangdese metallogenic belt and looking for the same type deposit in there. |
