Aragonite is a carbonate mineral it is a polymorph of the more common mineral calcite, it is mainly found in animal's shells.
The rock would be limestone, the mineral would be calcite.
Oxidised hydrogen does not make a mineral.
The usual name for such sedimentary rocks is conglomerate.
No, generally toothpicks are made of wood, which is not a mineral. Toothpicks can, however, be made of tough minerals like jade, or various metals.
Limestone is made of the shells of dead ocean organisms. Their shells are made of calcite.Hope i helped1 :)
Seashells are hard because they are mainly made of calcium, a hard mineral, which is what bones are made of.

Aragonite, a carbonate mineral.
Any Type Of Limestone
Aragonite is a carbonate mineral it is a polymorph of the more common mineral calcite, it is mainly found in animal's shells.
Mother of pearl is made from the shells of various molluscs , and is mostly various calcium carbonates. Go look at wikipedia.
It can be formed in this way, or it can be formed from calcite precipitation (mineral formation from saturated solution).
A conch shell is hard, cylindrical and is not jointed. A shrimp shell has many parts that move with the shrimp and provide protection. Additionally, the material that the shells are made of are entirely different. Conch shells are made primarily of a mineral called aragonite. Each layer of aragonite is reinforced by layers of protein. Shrimp shells are made of chitin, the same material insects exoskeletons, crab & lobster shells, and spiderwebs are made of.
We know that limestone is made up of those things, and some others. We also know that chalk, a kind of limestone, is composed mainly of tiny shells made of a mineral called calcite.
Very small pieces of stone, shells, and mineral sediment. Over time, large pieces of hard materials are ground by the ocean's waves into sand.
Coquina forms when shells, mineral calcite, and sometimes phosphate settle on the bottom of the ocean, while more and more pile upon them as time passes. Soon, as more pressure builds up, all the shells, mineral calcite, and phosphate press together to create a hard structure in the form of a rock called coquina.
