LOL, if I didn't read or understand an answer, I guess that entitles you to be rude. LOL! OK.
You say that the number one requirement for something to be considered sediment is that it comes from material that has been weathered and broken down. So can you give an example of this? For instance, as I understand it, and maybe I don't understand correctly, water can carry sediment. So please, what is an example of something that comes from material that has been weathered and broken down?
Examples of materials that have been weathered and broken down to form sediment are sand silt, clay, and gravel. These different weather and broken-down sediments can be traced mineralogically and physically to their geologic origin.
Examples:
Montmorillonite clays are weathered from volcanic ash or lava materials. The Hawaiian Islands are a classic example of the formation of soils from volcanic ash over periods of millions to hundreds of thousands of years at different ages of weathering of Ash and lava. You can see the beginning of soil formation of soil on recent ash and lava and progressively older soils over hundreds of thousands of years.
Rounded Quartz sand and pebbles are weathered from mostly Metamorphic rock like granite
Kaolinite clays weather from shales mostly wet environments.
Silt is wind-blown sediments sorted from sand, gravel, and clay by .the wind and deposited on the lee side of river systems. Depending on their chemical composition they can weather from a wide range of rocks.
Limestones are made of carbonate participates and coral reefs are deposited over millions to hundreds of thousands of years. The Bermuda Plateau is a coral reef and limestone deposited over millions of years on top of an ancient volcanic chain.
Along the coasts beach sands may be quartz sands deposited by rivers on the deltas and beaches..Also, many grains of sand along beaches are weathered sea shell fragments. A common shelly limestone along the coast is called Called. Coquina is made up of sand and gravel size pieces of shell and coral.
Weathering breakdown, depositing, and forming different kinds of rock take millions to hundreds of thousands of years. Many sedimentary rocks are made up of materials from older sedimentary, igneous, and metamorphic rocks.
Quartzite is a metamorphic rock made from sandstone by geologic heat and pressure deep in the earth. Newer sandstones often contain sand and gravel from Quratzite, therefore hundreds of millions if not billions of years for this to happen..
