Because the structure of chert varies greatly, I would recommend that you access the related link listed below- and refine your question.
Chert is NOT a metamorphic rock.
sedimentary rock
In the world of geology, the rock that rhymes with alert is chert. Chert is a type of sedimentary rock composed of microcrystalline quartz.
White chert is a microcrystalline sedimentary rock made up of silica. It forms in environments where silica-rich waters deposit material that solidifies into fine-grained, white-colored chert.
Chert is a type of sedimentary rock made up of quartz and has a cryptocrystalline structure. It is often considered the parent rock of flint, jasper, and agate due to their similar composition and formation processes.
Chert is cryptocrystalline quartz. It is considered a sedimentary rock, formed by a chemical crystallization process.
Chert is a hard, dense, sedimentary rock primarily composed of microcrystalline silica. It forms through the accumulation of silicon dioxide from dissolved quartz in water. Chert is commonly found in limestone formations and as nodules in other rocks.

Chalk is a form of limestone, a sedimentary rock.
Chert is a cryptocrystalline siliceous sedimentary rock. It resembles the physical properties of rocks having a glassy texture and a conchoidal fracture.
Chert is a sedimentary rock composed of microcrystalline quartz. It is formed by the accumulation of silica-rich skeletons of marine organisms, such as diatoms and radiolarians, or through the precipitation of silica from seawater.
