Anticline: a fold that is convex up and has its oldest beds at its core; usually recognized by a sequence of rock layers that are progressively older toward the center of the fold because the uplifted core of the fold is preferentially eroded to a deeper stratigraphic level relatively to the lower flanks

Buckle folding in the Chancellor Slate (cleaved limy mudrock) of eastern British Columbia.  At first it looks a lot like a series of microfaults, but in fact it is clearly pressure solution induced dissolution of some of the (now absent) rock along the prominent pressure solution seams (distributed cleavage or stylolites).

Figure 10  Photographs showing rhythmic lamination (A) and convolute lamination (B, C) in middle intertidal zone. Recessive laminae (arrows) in A and C represent sandier material deposited during spring tides. Diameter of lens cap (A) is 6.5 cm. Coin (B, C) is 2.5 cm diameter. Note that convolute lamination is sharply truncated by erosion surface (C). The sharply overturned anticline (C) suggests that deformation may be a result of downslope movement to the left.
