| The lower, evaporitic part of each cycle contains halite, anhydrite, and high salts. |
| These are hollow casts that partially fill the space once occupied by the original crystals of anhydrite. |
| It is dominated by the deposition of calcite with minor pyrite, marcasite, barite, anhydrite and gypsum. |
| The fine-grained matrix consists chiefly of gypsum, although traces of anhydrite may be present. |
| Middle Triassic anhydrite and dolomite form a sequence of strong reflectors, as does Lower Cretaceous sandstone. |
| He mentions that the amazonite occurred in association with orthoclase, smoky quartz, specular hematite, and rare anhydrite. |
