Is there a relationship between diagenesis and orogensis?
Orogenesis: The process of mountain formation, especially by a folding and faulting of the earth's crust Diagenesis: The physical and chemical changes occurring during the conversion of sediment to sedimentary rock. So, from one geologist to a non-geologist - I'd say no.
Diagenesis of sedimentary rocks?
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 are the four ways a mineral can form?
Crystallization from melt (igneous rocks)Precipitation from water (chemical sedimentary rocks, hydrothermal ore deposits)Biological activity (biochemical sedimentary rocks)Change to more stable state - (the processes of weathering, metamorphism, and diagenesis).Precipitation from vapor. (not common, but sometimes does occur around volcanic vents)Evaporation of mineral rich solutions
Does An intrusive igneous rock becomes a sedimentary rock?
Cementation is the process of deposition of dissolved mineral components in the interstices of sediments. It is the sticking together of sediment to form a new rock and is an important factor in the consolidation of coarse-grained clastic sedimentary rocks such as sandstones, conglomerates, or breccias during diagenesis or lithification. Cementing materials may include carbonates, quartz, iron oxides, or clay. (Source wikipedia)

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.
Is there a relationship between diagenesis and orogensis?
Orogenesis: The process of mountain formation, especially by a folding and faulting of the earth's crust Diagenesis: The physical and chemical changes occurring during the conversion of sediment to sedimentary rock. So, from one geologist to a non-geologist - I'd say no.
Why do some rocks have different minerals?
the reason is because rocks can have different depositional environments and diagenesis history.
