摘　　要：土耳其埃斯基谢希尔(Eski爧ehir)铬铁矿位于土耳其安纳托利亚高原中西部基性-超基性杂岩体中,是典型的阿尔卑斯型铬铁矿。该地区是土耳其重要的铬铁矿成矿区。通过对该铬铁矿矿床特征的研究,总结了土耳其阿尔卑斯型铬铁矿床的矿床地质特征。土耳其埃斯基谢希尔铬铁矿产于以辉橄岩、方辉橄榄岩为主要岩相的基性-超基性杂岩体内,矿体与围岩界线清晰,矿体大多呈豆荚状、囊状、脉状、透镜体状。矿石主要为致密块状和稠密浸染状,主要矿石矿物为镁铬铁矿、铁镁铬铁矿,矿石品位富,铬铁比高,为富矿矿石。Chromite in Eskisehir Province, Turkey was occurred in basic-ultrabasic complex bodies located in the midwest of Turkey＇s Anatolian plateau, which was the important metallogenic province of chromite in Turkey, and was a typical alpine-type chromite. The author carried out geological investigation and reconnaissance in recent years. Turkey＇s Eskisehir chromite occurred in basic-uhrabasic complex bodies whose main phases were composed of angite peridotite and harzburgite, the ore body was mostly in podiform, saccate, vein and lentieular shapes. The ore was mainly in massive and dense disseminated in form, the main ore minerals were magnesium chromite, iron-magnesium chromite with high ore grade.
