8. Conclusions
- The U-Pb age of hydrothermal calcite from the Lannigou Au deposit is 137 ± 9 Ma, indicating that this mineralization event was associated with Yanshanian tectonic movement.
- At the Lanmuchang Hg-(Tl) deposit, two samples yielded hydrothermal calcite U-Pb ages of 96 ± 2 Ma and 97 ± 9 Ma, demonstrating that this mineralization event was also related to Yanshanian tectonic movement. However, its ore-forming time was later than that of Carlin-type Au deposits in the YMP.
- The U-Pb age of hydrothermal dolomite from the Sixiangchang Hg deposit is 454 ± 21 Ma, indicating that this mineralization event was associated with the early Paleozoic Caledonian orogeny.
- Integrating previous chronological data, the low-temperature Au-As-Sb-Hg-Tl deposits in the YMP primarily underwent two phases of mineralization: one in the Late Triassic and the other spanning from the Late Jurassic to the Cretaceous, with the latter being predominant. Additionally, there exists a Paleozoic hydrothermal Hg mineralization event at the northeastern edge of the region.
