Geochemical characteristics of surface dune sand in the Mu Us Desert, Inner Mongolia, and implications for reconstructing the paleoenvironment

Metagenomics Reveal Correlations Between Microbial Organisms in Soils and the Health of Populus euphratica

“…Populus euphratica, a perennial woody plant with high salinity and aridity tolerance, is widely spread in Western China and adjacent Central Asian countries (Keram et al, 2019). Considering the growth habit of P. euphratica, the climatic and environmental conditions of the Yuyang District can be suitable for its growth (Shu et al, 2018). However, after several years of trying, the success of P. euphratica, which should be able to improve the ecological development in the MUD, has stagnated due to its high mortality rate.…”

“…Although proliferation of these species temporarily controlled the spread of the local desert and improved the local vegetation coverage, the limited biodiversity in the region renders the ecological environment fragile. The resulting risk of secondary desertification has always been an urgent problem for the ecological stability of the MUD region ( Shu et al, 2018 ; Li et al, 2019 ).…”

Mineralogy and Geochemistry of Al-Na'ma area Sand Dunes, Southeastern Tikrit, Northern Iraq

“…The major and trace element is used to identify the source of sand dune deposits [1]. The variation in the geochemical composition of sand dune sediment is related to the nature of the sediment source, mean grain size, and chemical alteration processes [41]. The chemical composition of studied samples reflects normal distribution for trace elements and significant oxide, but the UCC-normalized major oxides show CaO is enriched, while other oxides are depleted.…”
