Formation of limestone
A helictite is a speleothem found in limestone caves that changes its axis from the vertical at one or more stages during its growth. They have a curving or angular form that looks as if they were grown in zero gravity. They are most likely the result of capillary forces acting on tiny water droplets, a force often strong enough at this scale to defy gravity.
The limestone is a natural sedimentary rock formed from coral, algal, and fecal accumulation and includes many fossils and tiny fossilized organic debris and shell fragments. Limestones can also form by chemical sedimentary processes like precipitation of calcium carbonate from lakes or ocean water. These stones form amazing caves for the ...

If, over time, a body of limestone has been squeezed and deformed by great heat and pressure deep beneath the Earth’s surface, its structure and composition changes to form a recrystallised limestone known as marble, which can contain over 95% calcium carbonate. Marble is a hard crystalline rock that takes a high polish ... The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble.
