Study of Minerals in Potassium-Bearing Strata of
In this paper, some core samples from drill hole ZK1200B were studied by means of SEM-EDS (scanning electron microscopy with an attached energy dispersive spectrometer) and, as a result, four potassium-bearing strata were precisely recognized. There are a lot of solid salt minerals, such as sylvite, carnallite, polyhalite, epsomite, kalistrontite and celestite. Among them, kalistrontite and celestite were discovered in
