Structural Domes & Basins. Structural domes and basins are essentially circular anticlines and synclines, ...A dome-shaped anticline structure from the middle Bunter sandstone formation, typical for North Germany, has been used as a hypothetical but realistic storage site for this study. Limitations are given by the pressure limit on injection pressure as well as the requirement that all CO 2 in the CO 2 phase remains within the anticline structure. TheIn contrast to the other two examples, the Castilla Anticline appears to be unrelated to fault reactivation and basin inversion. Fig. 12.10 shows a domain of the Castilla Anticline where the uplift of the Castilla structure is even more pronounced than in Fig. 12.9.In this case, normal faults affect the outer-arc, crestal position of the Castilla structure.Extensive folding is represented by a repeated pattern of anticlines and synclines. Two anticlines are always separated by a syncline, and two synclines are always separated by an anticline. One side of the fold is called the limb; a side‐by‐side syncline and anticline share a limb. Frequently, an anticline or syncline can be identified ...dome, in geology, any large or elliptical structure formed by the fractureless upwarping of rock strata.It is a type of anticline that lacks clear-cut elongation and that slopes outward in all directions from the highest point.
