The weathering of rocks is reviewed, and 3 mechanisms recognized: differential parent-mineral weathering, boxwork/microboxwork formation of weathering products, and etch-pit formation on single mineral grains. The cave passage extends to a water filled sump at approximately 80 metres this cave is of particular significance for the limestone scalloping and boxwork weathering forms occurring in the entrance passage boxwork features are rare in australian cave systems significance: state.

The weathering of the rocks is also strongly influenced by the polygonal joint pattern seen in all turtle rocks carpet rocks (glossary of geology, 1987.

1 introductionas part of a more general pedogenic survey of a small watershed in west java (mulyanto, 1995), a detailed study on weathering under tropical perudic conditions has been made of a series of andesitic boulders present in the soil profiles. Of weathered limestone surface depends on its texture fig 5: outstanding of calcite veins was formed by selective corrosion weathered limestone is porous and wet in some places the beginnings of “boxwork” (palmer, 1981) is formed with outstanding of calcite veins (fig 5) and in the other places small rounded holes (fig 6) are presented. Ne syrtis location (lat,lon): 18n, 77e assess whether the kaolin-bearing materials represent weathering in a clement climate or acid boxwork structure.

Weatheringcrustandkarrenonexposed gypsumsurfaces some unusual weathering processes indu- other forms of boxwork type are the result of selective dissolution. The boxwork may be spongelike, triangular, pyramidal, diamondlike, or irregular in shape and may be coloured various shades of ochre and orange through dark brown the colour and shape of the boxwork can sometimes be used. Weathering, are scarce along the fractures, leaving a porous pseudomorph with boxwork structure, reflecting the original pattern of fractures (fig1.

As weathering progresses, clay- and oxide-bounded, porous “negative pseudomorphs” of the original minerals form micro-boxwork structures in the saprolite (velbel, 1989. Stratigraphy of outcrops, continued some exposures in the northern part of lyon county exhibit a yellow-brown boxwork it becomes shelly on weathering. Some honeycomb weathering occurs on man-made objects, such as buildings and walls made of stone softer rocks can form a honeycomb pattern but true honeycomb rocks, such as the ones i photographed in west virginia as part of this story, are caused by the confluence of several natural geological processes.
