| 中文摘要: |
| 东秦岭二郎坪地堑位于河南内乡夏馆—西峡二郎坪地区,大地构造单元属于华北板块南缘晚元古代—加里东期增生体,南北均有区域性深大断裂控制。区内金矿广泛分布,以热液叠加改造型为主。金矿床形成主要受含矿地层、构造、岩浆活动和高热流场控制,火山(沉积)地层提供了大量成矿物质,岩浆活动提供了热能和部分成矿物质,构造活动提供热液通道、成矿动力和成矿空间。 |
| 英文摘要: |
| Erlangping horst is situated in Xiaguan-Xixia-Erlangping area in Neixiang county and geotectonically at a Late Proterozoic-Caledonian accreted body in the southern margin of the morth China platform.The horst is bounded by regional faults in the southern and northern sides and within the horst area gold deposits are wide spread dominated by hydrothermal overprint-reworked type.The gold deposits are mainly controlled by ore bearing strata,structure,magmatiism and high hydrothermal fluid field.Volcanic(sedimentary) strata provide most of the ore materials;magmatic activity heat energy and some ore materials;structural activity metallogenic dynamics and ore-forming space. |
