The presence of PSS domains has been known from measurements of orientations and qualitative descriptions of field patterns of pressure solution seams (see for example, Alvarez et al., 1978; Mardon, 1988). However, it has not been a topic of strong interest to a degree that patterns of the domains and their variation were precisely documented. Here are some examples: Figure 1 and Figure 2 from Petit and Mattahauer (1995) and Watkinson and Ward (2006) from the Les Matelles limestone outcrops in the Languedoc region of France.

Figure 3 and Figure 4 are maps showing variable PSS patterns in sandstone in response to primarily contractional deformation and faulting in County Clare, southwest Ireland (Nenna and Aydin, 2011). Clearly in both cases shearing of either earlier pressure solution seams or veins played a crucial role. Other examples will be described and analyzed under 'Faulting based on Shearing of Initial Weaknesses' and 'Assemblages of Joints / Veins and Pressure Solution Seams.'

Figure 4. Map of the southern end of the southernmost sheared vein segment in Figure 1 showing a complex interplay between the splay veins (JV1), sheared pressure solution seams (PSS1), and splay pressure solution seams (PSS2). Arrows point out two of numerous pull-aparts such as those shown in Figure 3. From Nenna and Aydin (2011).
