Chemical Rock
Quartz and calcite are two minerals commonly found crystallizing out of ground water heated by magma. Quartz forms from the cooling of silica-rich solutions, while calcite forms from the precipitation of calcium carbonate in hot hydrothermal environments.
A cubelike class of minerals refers to a group of minerals that crystallize in the cubic or isometric system, characterized by their symmetrical, cube-shaped crystal forms. Common examples include halite, pyrite, and galena. These minerals often exhibit high symmetry and uniform properties in all directions, making them distinct in appearance and behavior. The cubic crystal structure is a key feature that influences their physical and chemical properties.
Minerals species which crystallize in the hexagonal division are apatite, beryl, and high quartz. Minerals of this division tend to produce hexagonal prisms and pyramids. Example species which crystallize in the rhombohedral division are calcite, dolomite, low quartz, and tourmaline. Such minerals tend to produce rhombohedra and triangular prisms.
A geode forms through a series of four key steps: First, mineral-rich water seeps into cavities in volcanic or sedimentary rock. Second, as the water evaporates, minerals precipitate and deposit onto the cavity walls. Third, these minerals crystallize over time, creating the inner structure of the geode. Finally, the outer shell solidifies, encasing the crystal formation, which can be revealed when the geode is cut open.
Chemical Rock
sedimentary rock
Chemical sedimentary rocks, such as limestone and chert, can form when minerals crystallize from seawater. These rocks are typically composed of minerals that precipitate out of solution in bodies of water, including oceans.
A Chemical Rock
Non-Clastic, or chemical, sedimentary rock is formed from dissolved minerals. These rocks are made of chemical sediments that have been dissolved from minerals. Solid minerals precipitate out of the solution in water. These minerals layer, and the water above them causes the pressure which forms the rock.
Quartz and calcite are two minerals commonly found crystallizing out of ground water heated by magma. Quartz forms from the cooling of silica-rich solutions, while calcite forms from the precipitation of calcium carbonate in hot hydrothermal environments.
Quartz and calcite are two minerals that can crystallize out of ground water that has been heated by magma. Quartz is a common mineral that forms in veins and geodes, while calcite is a carbonate mineral found in sedimentary rocks and hydrothermal deposits. Both minerals can be found in areas where hydrothermal activity has occurred near magma chambers.
Chemical sedimentary rocks, such as limestone and chert, are not classified by the size of clastic sediment that forms them, as they are formed from dissolved minerals that precipitate out of water. These rocks are made up of minerals that have been dissolved in water and then later crystallize out of solution.

Yes, geodes can sometimes have water trapped inside them. This water is typically formed when minerals are dissolved in the groundwater that fills the cavity of the geode, and then crystallize as the geode forms.
