Diagenesis - Diagenesis is the process that turns sediment into rock. The first stage of the process is compaction. Compaction occurs as the weight of the overlying material increases. Compaction forces the grains closer together, reducing pore space and eliminating some of the contained water. Some of this water may carry mineral components in solution, and these constituents may later precipitate as new minerals in the pore spaces. This causes cementation, which will then start to bind the individual particles together. Further compaction and burial may cause recrystallization of the minerals to make the rock even harder.
Other conditions present during diagenesis, such as the presence of absence of free oxygen may cause other alterations to the original sediment. In an environment where there is excess oxygen (Oxidizing Environment) organic remains will be converted to carbon dioxide and water. Iron will change from Fe2+ to Fe3+, and will change the color of the sediment to a deep red (rust) color. In an environment where there is a depletion of oxygen (Reducing Environment), organic material may be transformed to solid carbon in the form of coal, or may be converted to hydrocarbons, the source of petroleum.

Is chert metamorphic sedimentary or igneous?
Brick is baked mud, and as such, can be considered to be sedimentary.
What features of sedimentary rocks are unlikely to be found in metamorphic rocks what features of metamorphic rocks do not occur in sedimentary rocks?
ftygghhjgg
What is the or-gin of sedimentary rocks?
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
Is sedimentary rocks formed the same way normal rocks are?
No, because a sedimentary rock is formed from pieces of other rocks.
How do rocks breakdown?
diagenesis
Is chert metamorphic sedimentary or igneous?
Brick is baked mud, and as such, can be considered to be sedimentary.
What are the major processes involved in the formation of sedimentary rocks?
There are various processes that are involved in the formation of sedimentary rocks. This starts from weathering to deposition then erosion and finally there is lithification and compaction.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
What parts of the Rock cycle occur at the Earth's surface?
Mostly the sedimentary part which involves the process of weathering, and diagenesis occurs at the earths surface.

Are sedimentary rocks classified tofoliated sedimentary rocks?
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
Why do some rocks have different minerals?
the reason is because rocks can have different depositional environments and diagenesis history.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No. The rocks you describe are clastic or detrital sedimentary rocks.
What are the geological forces that made the Garden of the Gods in Colorado?
Sedimentary rocks are formed by deposition of either clastic sediments, organic matter, or chemical precipitates (evaporites), followed by compaction of the particulate matter and cementation during diagenesis. Sedimentary rocks form at or near the Earth's surface. Mud rocks comprise 65% (mudstone, shale and siltstone); sandstones 20 to 25% and carbonate rocks 10 to 15% (limestone and dolostone).[1]

Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
