The basic division of sedimentary rocks is into clastic and chemical rocks. Clastic rocks are formed when grains form a sediment and are then cemented together, as happens with sandstone or shale. Chemical rocks form when solid precipitates out of solution, for instance when calcium carbonate is formed from sea water to give chalk.

How do geologist classify sedimentary rocks?
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.

How many rocks did you classify as sedmentary?
sedimentary rocks are those which have been eroded from the earth and have had layers of mud and other rock put ontop of them, these then could create fossils. Some sedimentary rocks are such as limestone, mudstone, slate and marble.

They are called clastic sedimentary rocks.
Is gneiss clastic organic or chemical?
None of the above. These terms describe sedimentary rocks. Granite is igneous.
How do you classify rocks?
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
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.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No. The rocks you describe are clastic or detrital sedimentary rocks.
