A chemical sedimentary rock.
Evaporites are formed in this depositional environment. Salts, carbonates, and sulfates mostly. Halite, sylvite, calcite, gypsum, etc.
Halite is recognized by the IMA as a valid mineral, not a rock. According to the website linked below, "Halite is an evaporative sedimentary rock composed primarily of the mineral halite (sodium chloride)."
No, a geode is not a metamorphic rock. Geodes are formed in sedimentary or igneous rocks and are cavities lined with mineral crystals. Metamorphic rocks are formed from existing rocks that undergo a transformation due to heat and pressure.
Sedimentary rocks. Sandstone is a common example of a sedimentary rock that is formed from the accumulation and cementation of sand-sized grains of mineral and rock fragments.
Clastic sedimentary rocks: Formed from the accumulation of mineral and rock fragments that are cemented together. Chemical sedimentary rocks: Formed from precipitation of minerals dissolved in water. Organic sedimentary rocks: Formed from the accumulation of organic material, such as plants or animals.
Clastic sedimentary rocks are formed from the accumulation of rock and mineral fragments, while chemical sedimentary rocks are formed from the precipitation of minerals out of solution. Organic sedimentary rocks are formed from the remains of plants and animals. They differ in their composition, formation process, and appearance.
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.

Flint is a chemical sedimentary rock formed from the precipitation of silica rich solutions in layers of marine sediments.
Chemical sedimentary rocks form from solutions (water with something in it).

Clastic sedimentary rocks: Formed from the accumulation of mineral and rock fragments that are cemented together. Chemical sedimentary rocks: Formed from precipitation of minerals dissolved in water. Organic sedimentary rocks: Formed from the accumulation of organic material, such as plants or animals.
Clastic sedimentary rocks are formed from particles of pre-existing sedimentary, metamorphic, or igneous rock that are deposited, compacted, and cemented together by natural processes.Clastic sedimentary rock is made of fragments of rocks cemented together by a mineral such as calcite or quartz.
A mineral is a naturally occurring inorganic solid with a crystalline structure and a definite chemical formula. Most minerals are formed from the cooling or evaporation of solutions containing the elements necessary for mineral formation.
Clastic sedimentary rocks are formed from the accumulation of rock and mineral fragments, while chemical sedimentary rocks are formed from the precipitation of minerals out of solution. Organic sedimentary rocks are formed from the remains of plants and animals. They differ in their composition, formation process, and appearance.
Sedimentary rocks can form when minerals in a body of water have so saturated the water that they precipitate out, like a cloud that is so full of moisture that it pours out rain. Some limestones are formed in this manner as the mineral calcite precipitates out of a saturated solution and undergoes the process of compaction and cementation. The supersaturated solutions can also be caused by evaporation of a body of water high in mineral content. As the water evaporates, the mineral percentage of the remaining solution becomes higher and higher, until the mineral crystallizes. Rocks such as rock salt and rock gypsum are formed in this manner. Sedimentation from precipitation and evaporation form rocks called chemical sedimentary rocks.
