Typical minerals characteristics of host rock in the Tamusu pre-selected area    a Mixed laminae of mud-micro dolomite, analcime and argillaceous, Borehole TZK-2, 313.25 m, single polarization light; b mud-micro dolomite observed by SEM, Borehole TZK-2,752m; c field of views same as d analcime with first-order grey interference colors and, filling with dolomite. Analcime is mixed and distributed within the dark clay material, crossed polarization light, Borehole TZK-2, 638 m; e analcime crystals are dissolved into irregular tetragonal trisoctahedron, TZK-1, 593.53m; f typical tetragonal trisoctahedron analcime is observed by SEM, Borehole TZK-2,530 m; D1: mud-micro dolomite; D2: powder-fine dolomite; Ana: analcime; Ank: ankerite; Py: Pyrite
