那陵郭勒沙丘铁多金属矿区主要矿体1个，呈透镜状向斜式展布。初步认为成矿与印支期花岗闪长岩体有着密切的关系，围岩蚀变主要为矽卡岩化、硅化、绿泥石化、绢云母化及蛇纹石化，矿体受地层和岩体接触带控制。

나릉곽륵사구철다금속광구주요광체1개，정투경상향사식전포。초보인위성광여인지기화강섬장암체유착밀절적관계，위암식변주요위석잡암화、규화、록니석화、견운모화급사문석화，광체수지층화암체접촉대공제。
The one dominant iron ore body of mulimetal in Nalingguole sand dune synclinally extends in lens pattern.It is preliminarily considered that the mineralization is closely related with granodiorite of Indo-Chinese epoch,and its wall rock alteration are mainly skarnization,silication,chloritization, sericitization and serpentinization,which is controlled by strata and contact belts.
