Stratification is a visible feature of
sedimentary rocks. They are the layers you can see as the different types of sediment
CLASTIC ROCKS
SHALES
SANDSTONES
CONGLOMERATES
"Glue" holding the Clastic rocks together is either Calcite, iron oxide, or silica
PRODUCTS OF WEATHERING
QUARTZ
CLAY
CALCIUM CARBONATE/CaCO3
Classifying Sedimentary Rocks
TYPES OF SEDIMENTARY ROCKS
ORGANIC SEDIMENTARIES
Form from accumulation of organic debris (carbon containing)
Contain Calcite
CHEMICAL SEDIMENTARIES
Form when mineral constituents in solution
become supersaturated and inorganically precipitate.
CLASTIC
MATRIX
Mud/ grained sediment surrounding
clasts
CLASTS
Large pieces of sand or gravel
Form from weathering products that
don't dissolve in water
HOW ARE THEY FORMED
CEMENTATION
Precipitation of mineral matter in the space of the grains
, holding the grains together
COMPACTION
The new minerals are overlayed, forcing
forcing grains together
DEPOSITION
Sediment accumulates in a deposit area from a source area
WEATHERING
Igneous rock is broken down to form new minerals
