| 中文摘要: |
| 在湖南常宁水口山矿田中部,新近发现了一个隐伏的夕卡岩型铁多金属矿床。该矿床产于3号隐伏花岗岩体接触变质交代蚀变破碎带中,受控于倒转背斜、花岗闪长岩体超覆体、栖霞组灰岩与当冲组砂页岩构成的接触带“三角地带”,共伴生有铁、铜、铅、锌、银、金和铀。围岩蚀变组合复杂,其中石榴子石—透辉石—透闪石夕卡岩化、角岩化、硅化、大理岩化与成矿关系密切。矿床类型为接触交代成因的夕卡岩型。这一新类型矿体的发现,为水口山矿田隐伏矿体的找矿突破提供了新的方向与空间(隐伏岩体超覆体下接触变质交代带)。 |
| 英文摘要: |
| The skarn type iron poly-metallic deposit is discovered in central part of the well known Shuikoushan ore field recently. The orebody occurs in the contacted altered mineraliztion zone between No. 3 concealed granite intrusion and country rock. The orebody distribution is jointly controlled by overturned anticline, overlapping granodiorite intrusion, limestone of Qixia group and sandy shale of Dangchong group which formed a triangle structural zone. Main mineralization and associated elements are iron, copper, lead, zinc, silver, gold and uranium. The wall rock alteration varies is complex including garnet- diopside - tremolite skarn, hornfels, silicification and marbleization which are closely related to mineralization. The deposit type is contacted metasomatic skarn type. The discovery of new type orebody provides a clue for prospecting concealed orebody in the depth of Shuikoushan ore field, i.e., it is probably for finding new orebody in the contacted metamorphic zone under overlapping granite intrusion. |
