What is a sediment? As Tom Garrison, a science professor, defines sediment "particles of organic or inorganic matter that accumulate in a loose, unconsolidated form." (Marine Science 100pg. 47). The classification of sediments may be put in their source which pertain to be terrigenous, biogenous, hydrogenous, and cosmogenous. Each one of the sediment sources contains a different mineral composition and may be found at different places in the ocean or beach. Specifically, terrigenous sediments which "originate on the contientes or islands from erosion, or volcanic eruptions, and blown dust." (Oceanography pg.143) pertain to be "the most abundant"(Oceanography pg.134) in the beach where the sand is all the way the shelf. …show more content…
For example, in the red sand beaches in Hawaii are "a result of a nearby cindercone that is rich in iron and has eroded over many years."( To-Hawaii.com), and the beach's name is Kaihalulu Beach. Thus, to restate the primary mineral in this beach is iron. Let us compare this beach to Newport Beach. In Newport beach the primary minerals pertain to be quartz, feldspar, magnetite, and shell fragments (biogenous). Thus, Newport Beach's main minerals are due to the fact that sediments mainly come from the mountains, rivers, and blown dust. Terrigenous sediments that are from mountains have granite, and the mineral in granite is quartz, and rivers must drain minerals like magnetite and feldspar(possible biogenous) to the beach. Also, beaches in the Louisiana differentiate from Newport Beach due to the fact the Mississippi River runs to the ocean which picks up mud from the land and mud contains clay as mineral. Secondly, the mineral composition depends on how old the beach is. For instance, a new island beach in Hawaii will most likely have a high amount of quartz that derives from granite, because Hawaii is forming through mainly volcanoes. This gives a hint, especially since magma makes granite and granite has the mineral composition of quartz. Minerals like feldspar, that may be biogenous, might not be
