摘 要: | 通过开展甘肃1∶5万莫坝尔等六幅区域地质调查工作,系统查明了区域地层、岩石、构造等地质特征和成矿地质条件,建立了区内地层格架和岩浆岩演化序列,查明了测区基本构造格架,并总结了本区的构造演化历史;新发现余石山大型铌钽稀有金属等矿床和矿(化)点24处,在此基础上在测区划分出找矿前景较好的4个成矿远景区,为后续找矿工作提供了基础地质资料。

Abstract: | In the regional geological survey of six 1∶50,000 sheets of Mobaer, etc., Gansu province, geological characteristics of the regional strata, rocks, structures and metallogenic geological setting were identified; the stratigraphy framework and magmatic evolution sequence were established; and the basic tectonic framework and evolution was summarized. In addition, 24 mineral deposits (occurrences) were discovered, such as the Yushishan large-size Nb-Ta rare metal deposit. Accordingly, the researched area was divided into 4 ore-forming prospects, which provided significant basic geological data for further ore prospecting. |
