Magmatic-hydrothermal gold deposit.
The Longtougou gold deposit extends >2500 m E–W and ∼1000 m N–S. The deposit hosts a number of orebodies, with the seven largest orebodies termed I-1, II-1, III-1, IV-1, V-1, V-2, and VI-1. These orebodies are elongated WNW to EW, are generally parallel to each other but cross-cut the bedding of the host rocks, have transitional boundaries with the surrounding country rocks, and are generally delineated by chemical variations. The I-1 and IV-1 orebodies are larger than the other orebodies in the study area. Orebody I-1 is ∼1200 m long, 0.21–3.59 m wide, and has an average gold grade of 3.58 g/t. The orebody is fault controlled and vein-hosted and has good continuity, although it is undulatory, bifurcates, and reconnects in places.
