The salts deposited by the lake brine were mineralogically identified by XRD analysis and include not only calcite and dolomite, but also trona ([Na.sub.2]C[O.sub.3] x NaHC[O.sub.3] x 2[H.sub.2]O), burkeite ([Na.sub.2]C[O.sub.3] x 2[Na.sub.2]S[O.sub.4]), and halite (NaCl), thus confirming the mineralogical similarity between these deposits and those from Wadi Natron in Egypt.
