Is Granite Or Sedimentary Older

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Is granite or sedimentary older.

If rounded pieces of granite are pebbles in a layer of conglomerate that lies on top of the granite then the granite must have been exposed weathered and eroded prior. Limestone is a sedimentary rock laid down in the oceans millions of years ago. One easy way to. Driven by the fluid pressure the sediment breaks.

No granite is an igneous rock. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Essentially they are comprised of layer upon layer of sediment easy to remember sediment sedimentary build up over time.

But you could have had an igneous rock millions of years ago that was weathered and eroded into sediments that then became the sandstone. Then later a new pluton cooled creating new granite that is younger than the sandstone. When shallow unconsolidated sediment is composed of alternating coarse grained and impermeable clay layers the fluid pressure inside the coarser layers may reach a critical value due to lithostatic overburden. Limestone does turn into marble when subjected to huge.

Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. When this happens new minerals may form and older pre existing minerals grow and change shape or shrink and even disappear completely. Sedimentary rocks form as a result of weathering and deposition from previously formed rocks and are usually much softer than igneous or metamorphic rocks. Sedimentary rock cannot be radiometrically dated you would only be dating the clasts themselves not the rock unit.

Granite is an igneous rock originating from volcanic activity. Strictly speaking granite is an. Sedimentary dikes or clastic dikes are vertical bodies of sedimentary rock that cut off other rock layers. The principle of inclusions a piece of rock that is included in completely surrounded by sedimentary rock is older than the sedimentary rock in which it is included.

Sedimentary rock formation lacks the heat and pressure that created the igneous rock. Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone sandstone is defined as a rock which is composed of sand sized grains of various minerals mostly of uniform size and often are smooth and rounded. They can form in two ways. It forms due to crystallization from magma.
