| The First Precipitation of Antarcticite in Solar Ponds in China |
| Antarcticite, formed in areas of very arid and cold climate, was first discovered in the Don Juan Pond in Victoria Land, Antarctica. The mineral is named after the place it was found. The Antarcticite was reported to be found in Qaidam basin in 1983. Nanyishan area of Qaidam basin is also extremely dry and very cold, especially in winter. A solar pond experiment was carried out to extract potash in Nanyishan from the underground brine at the depth of 1940 m, which is rich in calcium and potassium. In the experiment, the Antarcticite was crystallized out in the solar pond with halite and potash during the winter. The X-ray powder diffraction measurement, chemical analysis and crystal optical study of this mineral has proved that the mineral is Antarcticite. This is for the first time that the Antarcticite is reported in solar ponds because there was no such report before. Through the research, the climate environment for the formation of Antarcticite is determined. The results obtained by the authors will give some useful information to the study of the environment changes in Qaidam basin. |
