Geological Structures: a Practical Introduction

Even without looking at boundaries, you may be able to see structure in a rock unit: the properties of many rocks vary with direction because the mineral grains are aligned with one another: we say the rock has fabric, another type of structure.

Reservoir geology

Many major oil fields in the world were discovered by using surface mapping to locate domal structures. A more complex method of forming a structural trap is by faulting and structural uplift (see Fig. 1). Faulted structures can vary from a simple faulted anticline to complex faulting around piercement structures and domal uplifts.

1.3: Primary Structures

Unconformities. Unconformities are ancient surfaces of erosion and/or non-deposition that indicate a gap or hiatus in the stratigraphic record. An unconformity may be represented on a map by a different type of line from that used for other geological contacts; in a cross-section an unconformity is often shown by a wavy or crenulated line.
