Figure 15
Dike-perpendicular (A–C) and dike-parallel (D–F) vertical cross sections through the reservoir model. The Contrin Formation, at the base of the model, is completely dolomitized. Similarly, the top of the model consists of 100% limestone, based on field observations, which are not interpolated. This results in sharp upper boundaries of the dolomite bodies. (A) Vertical dolomite chimneys can be observed that rise up from the Contrin Formation. (B) Not all dolomite bodies are connected directly vertically to the Contrin Formation but have a horizontal connection to a dolomite pipe. Isolated dolomite bodies only account for 10% of the total dolomite volume. (C) Not only do vertical dolomite pipe rise up high into the Latemar Formation, wide triangular dolomite bodies also exist. (D and E) Parallel to the dikes, dolomite pipes are not always vertical, but large dolomite pipes are always rooted in the Contrin Formation. (F) Sub-vertical dolomite pipe with horizontal dolomite bodies.
