| 中文摘要: |
| 甘肃省肃北县金庙沟南硅灰石矿床产于敦煌岩群C岩组三岩段的石英硅灰大理岩与花岗岩的接触带及其附近，矿体呈透镜状、似层状产出。矿区共圈出硅灰石矿体16个，矿体长96~818 m，矿体厚度在1.20~12.33 m之间，矿石品位为φ（硅灰石）=35.53%~51.62%，含矿岩石为石英硅灰石大理岩。矿石的类型可分为团块状硅灰石-方解石-石英型矿石、薄层状硅灰石-方解石-石英型矿石。在矿床地质特征研究的基础上，对矿床成因类型进行了分析，提出了找矿标志，对甘肃北山寻找同类矿床具有借鉴意义。 |
| 英文摘要: |
| Jinmiaogounan wollastonite deposit in Subei County, Gansu province, is located in the contact zone between quartz wollastonite marble of the third member of C formation of Dunhuang group and granite and the vicinity. The ore body is lenticular and stratoid. There are 16 wollastonite ore bodies in the mining area with length 96 m-818 m and thickness 1.20 m-12.33 m and content of wollastonite 35.53%-51.62%. The host rock is quartz wollastonite marble. The ore types can be divided into two types:spoted wollastonite-calcite-quartz ore and thin layered wollastonite-calcite-quartz ore. Genesis of the deposit are analyzed and the prospecting marks established that refered to prospecting of the same kind of ore deposit in Beishan, Gansu Province. |
