Clarify geochemical, mineralogical and technical features of surface saline mud from southwestern sub-basin of the East Vietnam Sea and their application.

Theoretical results:
- Twenty mud samples in 8 gravity cores taken from the southwestern sub-basin East Vietnam Sea were treated for analysis of grain size, inorganic and organic geochemical and physicochemical parameters to assess the use of mud samples as peloids and rare earth elements potential as well as the provenance of sediment at the studied area.
- Based on interpretation of results of trace elements, mineralogy and isotopic composition, the mud samples were proved to have continental provenance, and Mekong river-derived sedimentary material appear to have main contribution.
Applied results:
Studied results revealed that micro-grained mud samples are very suitable for peloids, accept the case of samples of core LV88-12GC which relate to hydrothermal activity-derived sulfur-rich compound.
Mud samples have the total amount of rare earth elements in range of 241,37 to 412,92 ppm. This result suggests the applicability of mud samples for rare earth element exploitation at the studied area.
