MARGIN: 0cm 0cm 0pt" class=MsoNormal> mary name="EnDivSummary">Potassium and magnesium salt deposit mainly enriches in the lower gypsum rock salt segment of Tagong Formation in mas-microsoft-com:office:smarttags" />Vientiane Basin, Laos. The deposit is mainly composed of salt rock, carnallite, potassium salt, carnallite bearing potassium and a small amount of spar etc, and it belongs to single-layer structure. Trace elements of potassium and magnesium salt deposit such as Br and Rb are directly related to chloride, and therefore work as sign of potassium deposit prospecting in the Vientiane Basin. The conclusion can be quite helpful to enrich the ancient solid potassium salt mineralization theory and to guide the research of Lanping-Simao Basin evaporate salt and other potash deposits prospecting. mas-microsoft-com:office:office" />
