Caves caused by volcanic activity are made of basalt Caves caused by dissolution due to groundwater are formed in limestone or sometimes marble. Caves also form in glacial ice due to melting. (Glacial ice can technically be considered rock.)
A Hybrid science combining the study of Caves and Glaciers. Ice Caves, popular in Europe, would fit into this scientific categoryl.
They are not somuch large because they are full of ice, but happen to be large caves thataccumulate a lot ofice; and the size ofany individual cave depends on awhole (hole? -sorry!) range of geological, hydrological and climatic factors specidif to that cave and its location.
World's largest ice cave presently known is in Austria: the Eisriesenwelt. It's a normal limestone cave with >42km of known passages, many richly decorated with lovely ice layers and formations. Show-cave in parts.
They don't really have "weather". There is no precipitation for a start, and little seasonal variation. The mean air temperature in most caves of any extent is fairly stable at that of the mean annual air temperature of the region in which they lie, or a little lower, but this can be affected by changes in air circulation or stream-levels. Bats exploit this in choosing caves as roosts, nurseries or hibernaculae, the last being preferably slightly cooler, and they often migrate from one to the other. A few UK show-caves are used also for maturing cheeses, thanks to the cool, dark, humid and stable conditions. And very nice cheese it is too! The air in most caves does circulate, and caves can be pervaded by strong draughts. Cavers use the draught to guide them in searching for "new" caves or extensions to known ones. Caves in temperate areas especially are very humid, and this plus the cool air can create mist that can be the bane of cave photographers. A few caves in high Alpine areas are pervaded by ice formations coating their rock surfaces - the Eisriesenwelt in Austria being a classic example.
Tom Swift in the Caves of Ice was created in 1911.
True ice-caves develop under glaciers. Some high-altitude caves like the Eisreisenwelt are described loosely as ice-caves thanks to major ice deposits within them, but they are still caves formed within rock. The ice is merely coating the walls and roofs.
Tom Swift in the Caves of Ice has 200 pages.

There are ice caves south of Port Sarim. There is a dungeon entrance a little north of Mudskipper's point, and when you enter it, you must follow the tunnel and you will find the ice caves. You will pass muggers, pirates, and hobgoblins and then will enter a cave with ice giants and blurite mining rocks.
