Quartz vein-type and altered granite-type tungsten and minor tin mineralization.
The Dongdouya deposit is the only known occurrence of economically significant tin mineralization, with estimated reserves of 7,446t Sn at an average grade of 0.45 %. It covers an area of 2.07 km2. The mining area is structurally controlled primarily by two NNE-trending compressional-shear faults and four NW- to NNW-trending tensional-shear faults. Exposed intrusive rocks in the deposit include Jinningian biotite granodiorite, Yanshanian muscovite granite, and biotite granite porphyry. Field relationships indicate that the biotite granite porphyry intrudes and cross-cuts both the muscovite granite and the Sn ore veins, representing a later-stage magmatic phase. A total of four ore bodies have been delineated in the deposit. Ore body I is Sn-dominant (comprising sub-bodies I-1, I-2, and I-3), with ore minerals consisting predominantly of cassiterite and minor wolframite. It has an average thickness of 5.39 m. Sn grades average 0.45 % and reach up to 4.95 %, with estimated reserves of approximately 7,446 t Sn. (Js II, III, and IV are W-dominant, characterized by ore minerals dominated by wolframite with minor molybdenite and cassiterite, with estimated reserves of 13,112 t WO3 at an average grade of 0.24 %. In this study, we focus primarily on ore body I, which occurs as lenticular masses of varying scales within the inner and outer contact zones of the NE–SW-striking muscovite granite stock, extending over 800 m in the E–W direction and ranging from 160 to 540 m in the N–S width. Between Ore bodies I-1 and I-2 lies a residual roof pendant of Jinningian biotite granodiorite, ranging from several meters to several tens of meters in thickness. Drill core logging reveals that ore bodies I-1 and I-2 are interconnected at depth, forming a U-shaped tabular ore body. Two types of tin mineralization have been recognized in the Sn-rich ore bodies, namely greisen-type and altered granite-type.
