新疆塔县阿依里西铁矿地质特征及找矿意义

摘要

阿依里西铁矿位于华南板块的羌唐微板块北缘与塔里木板块墓士塔格地块结合部位，产于古元古代布伦阔勒群变质岩系中，矿体呈似层状、层状产出，矿石自然类型为磁铁矿石，属“鞍山式”沉积变质型铁矿，经济储量可观。该铁矿的发现、勘查及开发，对缓解新疆铁矿石资源紧张状况有极大的促进作用。该文简要分析了该铁矿的成矿特征和赋存状态，探讨了该区的找矿方向。%　　AyilixiirondepositislocatedinthecombinationpartofnorthedgeofQiangtangmicro-platein theSouthChinaplateandMushitageblockofTalimuplate.ItoccurredinmetamorphicrocksofthePaleo-proterozoicBuluokuolegroup.Itsorebodywerestratiformandlayeredtype.Itsnaturaltypewasmagne-titeores,andbelongedto"Anshantype"metamorphicirondeposit.Itscontrollingeconomicandbasicre-serves(122b)were33.14milliontons,inferredintrinsiceconomicresourcesamount(333)was733000t, predictedresourcesamount(334)was7971milliontons.Therewere400millionto500milliontonsofore resourcesaroundingtheworkregion.Discovery,explorationanddevelopmentofAyilixiirondeposithave agreatroleineasingthelackofironresourceinXinjiangUygurAutonomousRegion.Inthispaper,char-acteristicsandoccurrenceofironoremineralizationhavebeenanalyzed,andprospectingdirectioninthis areahasbeenputforwardaswell.
