It takes the form of ledges that tend to be flat on top and sloping underneath. They are almost always formed from calcite, when materials precipitated from dripping water onto a cave pool attach to the side. The deposition continues to grow laterally, underneath.
The shape is that of ledges with a flat top and a downward slope. These are predominantly made from calcite, formed by the deposition of materials on cave pools where water drips down. This process causes the formation to extend laterally underneath.
