In the monsoon tropics of northern Australia, a strongly-developed karrenfield is intimately associated with extensive underlying epikarstic maze caves. The caves, and the mesokarren and ruiniform megakarren are mainly restricted to a flat-lying, 20 m thick, unit of interbedded limestone and dolomite. However, microkarren are mainly found on the flaggy limestones of the overlying unit. These are the best-developed microkarren in Australia, and possibly worldwide. A retreating cover results in a zonation of the main karrenfield from a mildly-dissected youthful stage at the leading edge through to old age and disintegration into isolated blocks and pinnacles at the trailing edge. Cave undermining has formed collapse dolines and broader subsidence areas within the karrenfield. Tufa deposits occur in major valleys crossing the karrenfield. The karrenfield shows some similarities to other tropical karren, including tsingy and stone forests (shilin), but in this area there has not been any initial stage of subcutaneous preparation
