Caves often are formed thru several formations of rock from various times in the geologic history of the cave. It is possible that a limestone sits on top of some other sedimentary rock like gypsum. The same cave will completely change character as it passes through to a different layer. Sometimes 2 good soluble layers are separated by a layer that is not soluble and the water doesn't easily make it thru the sandwiched layer.
Sedimentary Rock is made up of layers of different rocks.

There are different kinds of trimmer capacitors, but the most common type is made from interleaved layers of metal and Mylar (or some kind of plastic) with a screw that allow the layers to be tightened together, increasing capacitance as needed. Alternate layers of metal are connected to each terminal, basically making a meshed plate capacitor, where the distance between plates is controlled by the screw.
it was made by using various layers of crystal
