| Abstract: | Sedimentary facies is firstly divided in the Shalagang Sb(Au) mining area, and all kinds of characteristic gravity flow sediments, for example, slide, debris flow and turbidity deposits, are significantly documented. The well known gravity flow sediments were formed by the debris, slide and turbidity flows in the Late Jurassic Early Cretaceous, which consisted of the slope clastic rocks and interbeds of siliceous rocks and limestones. The lithofacies assemblages of the upper slope, lower slope and submarine fan emerged in the slope. The upper slope was characterized by kinds of sliding sediments and the lower slope by debris flow sediments . The submarine fan can be divided into progressive and regressive sequences, which are composed of sandstone bodies formed by turbidity flow. They provide abundant informations of sedimentary geology for analysing Sb(Au) mineralization in the Shalagang mining area. |
| Keywords: | Tibet Shalagang Gyangze gravity flow sedimentary facies |
