The Yilanlike pegmatite, which primarily comprises carbonatitic phlogopiteโ€“diopside pegmatite, biotiteโ€“nepheline pegmatite, and granitoids, is a typical Zrโ€“Nbโ€“Taโ€“REE-mineralized alkalineโ€“peralkaline pegmatite in this belt. The nepheline pegmatite is the most Zr-enriched rock type at Yilanlike, containing numerous zircon megacrysts that are centimeters in scale. The Yilanlike rare metal and REE deposit is located 36 km north of Heiyingshan county in the Xinjiang Uygur Autonomous Region, along the northern margin of the early Paleozoic forearc accretionary complex of the STOB. The sedimentary sequences exposed in this region mainly belong to the Paleoproterozoic Xingditage Group and Silurian Keketiekedaban Formation. Igneous rocks mainly occur in the Xingditage Group. Folds in this area is mainly related to the northwestโ€“southeast-trending Yilanlike anticline. The core and limbs of the anticline comprise the Lower Xingditage Formation and Upper Xingditage Formation, respectively. Igneous rocks mainly consist of early Permian granitoids (mainly biotite granite and monzogranite), alkaline rocks (nepheline syenite, nephelinite, carbonatite, and alkaline granite), pegmatites, and mafic rocks. The alkaline rocks, mainly intruded marble in the upper portion of the Upper Xingditage Formation. A total of 75 pegmatite veins occur in the Yilanlike deposit . Twenty-two of these pegmatite veins have been identified to host rare metal and REE mineralization, 18 of which are alkalineโ€“peralkaline in composition and 4 are granitic in composition. The alkalineโ€“peralkaline pegmatite veins mainly occur in the western portion of the Yilanlike deposit, have lengths and thicknesses of 30โ€“200 m and 5โ€“10 m, respectively, and consist of nepheline pegmatite and diopsideโ€“phlogopite pegmatite.
