Large gully known as Shaanxi Huanglongpu molybdenum deposit molybdenum deposit, it Jinduicheng molybdenum mine located about 12km, but the genetic type and Jinduicheng molybdenum mine are very different, as the carbonate vein-type molybdenum deposit. Maintain molybdenum reserves 115 000 t, 0.086% molybdenum grade. Molybdenum ore industry is mainly composed of molybdenum (lead) composed of quartz calcite carbonatite veins. According to the delineation of ore grade molybdenum bedded and lenticular. Veins to large-scale, complex ore material composition, rich in molybdenite rhenium, and calcite closely with molybdenite, unlike neighboring Shijiawan JINDUICHENG and two porphyry molybdenum deposit. Veins were large veins (also stockwork) output, generally long tens to more than 100 m, the longest of around 500m, width of 0.1 ~ 1.0m, the most wide and 20m. Single veins form more regular, and constitutes stockwork veinlets.
Complex composition of the ore material, identified ore and gangue minerals metallic minerals and 33 species.
Complex composition of the ore material, identified ore and gangue minerals metallic minerals and 33 species.
Output mode molybdenite are:
① sparse or dense disseminated distributed in calcite, quartz and also visible;
② thin film was produced in the vein walls or one wall;
③ vein wall was nearly carbonation spilite in star-shaped distribution;
④ microscopic studies show that molybdenite cleavage filling in pyrite, rutile, biotite, feldspar and barium lapis lazuli, and fissures, and filling - accountable quartz. Wall rock alteration is limited to the deposit veins on both sides, showing a linear characteristic alteration vein deposits possess, alteration types are: biotite, epidote petrochemical, pyrite, carbonate of , anhydrite and zeolite based technology, in which the carbonate into the characteristics.
