Speleothem is the general term of a secondary generated sediment (Stalactite, Stalgmite, etc). Stalactite is sediment which carried out the overhang and which has fallen. Stalactite is the generated sediment of calcite which the tip sharpened and was influenced by gravity. Stalgmite is the deposition form which became a drop from the crack and fell.
The limestone is the sedimentary rock which the accumulation of the creature body and the layer that was crushed fragment (the calcareous shell and the build) can make.There is one which precipitate can do scientifically with the part, too.
Limstone cave is formed in rimstone, underground lake, melt pipe, etc. corrosion is formed into a rock called limstone and dolostone which are easy to dissolve in rain and groundwater. A limstone cave and a dolostone cave photograph are formed of corrosion.
Lava is general term which constitute the rock of the substance in a molten state. Lava is used for the flow on the surface of the earth from a volcanic crater, and the solidified volcanic rock. The raw materials of the exhibited main ingredients are four ingredients of SiO2, Al2O3, and Mgo and Fe2O3.
The lava cave photograph : The lining layer, the coffin, the lava shell, the lava shelf to compose while generated in the morphosis of the volcanic lava flow by the lava cave, a lava bridge and a lava waterfall and so on are formed.
The model of a limestone cave is the stalactite group which a height of 53cm of the stairs on the first floor and the second floor used. They are 80 sorts of stalactite(s) at a ceiling. They are 70 sorts, including 50 sorts of stalagmite in an intermediate part. They are the upper part and 150 sorts in all of stalactite groups.
