Punaiki, New Zealand. The 'Pancake Rocks'. The layers of limestone are believed to be formed as a result of a secondary precess called stylobedding. After being buried and compacted, grains of shell and sleleton were put under such pressure that they pass into solution. Some minerals merged to form thin seams of mudstone between layers of limestone. The forces of sea and weather during the past 100,000 years have eroded the mudstone more than the limestone, enhancing the 'pancake' effect.

Remarkable Rocks, Kangaroo Island, South Australia. Examples of cavernous and spherical weathering in granite set atop a granite outcrop 75m above the sea. The rocks are covered with an orange lichen that dominates in areas of high salinity.
