What is a structural style?
Structural styles or structural families are associations of structures that often occur together due to a common origin. For example, major foreland thrust belts usually contain a mixture of listric reverse or decollement thrust faults, large asymmetric hangingwall folds, and late listric normal faults. These features are arranged to form an overall arcuate deformed belt. There is little or no involvement of mechanical basement in the deformation. Individual structures generally have good strike continuity and poor depth or dip continuity. Hence, in any newly discovered thrust belt, these same associations (thrust belt structural style) would be anticipated, modified somewhat by local geology. The concept of structural styles and their classification are given in Harding and Lowell[1] and Lowell.[2]
Choosing techniques
If and when a structural style(s) is ascribed to an area, certain of the structural techniques become more important to perform than others. The list below displays those techniques (keyed to the numbers in Figure 2 of Workflow to find a prospect) deemed important for each major structural style.
| Style | Very Important* |
|---|---|
| Thrust belts | 5, 8, 10, 12 |
| Wrench systems | 1, 3, 11 |
| Rifts and detached normal fault systems | 2, 8, 10, 12, 15 |
| Diapiric | 2, 12 |
| Foreland block folds | 3, 6, 8 |
| Basement warps and sags | 2, 6, 8, 11 |
