The photograph and the sketch in Figure 1 show a field case with multiple sets of compaction bands including one set parallel to approximately horizontal bedding and related low-angle, wiggly splay compaction bands in the middle unit, and high-angle compaction band sets in the units above and below. Figure 2 shows variation of compaction band domains across multiple dunes (Deng and Aydin, 2012). The influence of the variation of the cross-beds on the formation of the different compaction band domains are briefly described under the 'Mechanisms and Mechanics of Compaction Band Domains.' This case displays spatially compartmentalized compaction bands into depositional cross-bed domains (Deng and Aydin, 2012) and will be further commented on under 'Porosity and Permeability of Compaction Bands' and their impact on fluid flow across sandstones with various compaction band domains (Deng et al., 2016).

Figure 1. Two distinct compaction band domains in adjacent dunes. The upper dune contains compaction bands at high-angle to the cross beds and the lower dune has low-angle bed-parallel compaction bands.

Figure 2. Map showing a series of dunes (D1 to D27) trending northerly and from old to young age progression to the east. Cross bed domains in each dune are also shown. Domains with only bed-parallel compaction bands, domains with only high-angle to bedding compaction bands, and domains with overlapping bed-parallel and high-angle to bedding compaction bands are color-coded. Location of traverse AB is marked. From Deng and Aydin (2012).
