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 form consists of ledges with a flat upper surface and a downward slope. These are typically composed of calcite, formed by the accumulation of materials that precipitate from dripping water on cave pools. This process causes the deposition to spread out underneath.
