| Abstract: | The gold deposit in Oudomxay Province,northern Laos,is a meso low temperature hydrothermal vein type gold deposit controlled by structure.The late Paleozoic Carboniferous Permian strata(C-P1)are mainly exposed in the northwest,and the Mesozoic Jurassic(J2)strata are exposed in a small range in the south.The ore types can be divided into weathering residual enrichment type,alteration rock type and gold bearing quartz vein type. |
