摘要：摩洛哥东北部贝尼布·伊弗罗尔矿床为夕卡岩型磁铁矿。K-Ar年龄测定表明，成矿作用发生在7.040.47 Ma。维克桑花岗闪长岩岩基的夕卡岩与岩脉的空间关系以及年龄的相似性(8.020.22 Ma)，证实维克桑花岗闪长岩是最有可能与成矿有关的火成岩。夕卡岩在石灰岩中呈不对称分布，磁铁矿在钙硅酸盐夕卡岩的正下方发育为两个平行层，相隔100m的贫灰岩和片岩。
Abstract: The Beni Bou Ifrour deposit of northeastern Morocco is a skarn type magnetite deposit. K‐Ar age determination suggests that the mineralization occurred at 7.040.47 Ma. The spatial relationship between skarn and dikes of microgran‐odiorite derived from the batholith of Wiksane Granodiorite, and the similarity of age (8.020.22 Ma), confirms that the Wiksane Granodiorite is the igneous rock most probably related to mineralization. The skarn is distributed asymmetrically in the limestone, and magnetite ore was developed just below the calc‐silicate skarn as two parallel beds separated by 100 m of barren limestone and schist.
