Where are the oldest fossil located?
The worlds oldest fossils were found in an ancient beach in Austrila, they are 3.4 billion years old and are fossils of cells. They have no bones and are mineralized spheres.
What is the oldest rock in earth?
Igneous Rock
What part of the sedimentary of rock is the oldest?
Protolith is a term used to describe the parent rock of a metamorphic rock. Conglomerate is a sedimentary rock that can be composed of clasts of sedimentary, igneous, or metamorphic rocks, or any number of combinations of all.
Is metamorphic rock the oldest type of rock?
slate
What is special about igneous rock?
Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction. When these igneous rocks are exposed to weathering and erosion, it is called cleavage. They break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock.

Would the oldest rocks on earth be igneous or sedimentary?
The creation of igneous rock from magma is dependent on the cooling rate of the magma. Some igneous rocks form almost instantaneously, and others take hundreds of thousands of years. So igneous rock could be the youngest of the three rock types at any given point in time.

What kind of rock is found in stone mountain?
In northern Georgia, you will find the southern terminus of the Appalachian Mountains, arguably the oldest mountain range on earth. The mountains date from the Permian time period of earth's history, around 300 million years ago. These mountains are igneous (volcanic) in origin, but in the huge amount of time since then, are also metamorphic. In southern Georgia, since rivers and streams drain the area, the rocks are largely sedimentary, composed of igneous and metamorphic rocks from the north laid down in riverbeds and deltas.
Is metamorphic rock the oldest type of rock?

How old is the Devil's Tower monument?
The oldest visible rocks at the Devil's Tower monument are 225 to 195 million years old, from the Triassic period. During the Paleogene period, when the Rocky Mountains and the Black Hills were thrust up from the crust 65 million years ago, magma pushed up into the sedimentary rock layers, an intrusion of igneous material geologists agree created the formation.

What is the world's oldest dated mineral?
The oldest mineral is somewhat controversial as the dating error of such old objects is millions of years; the oldest so far dated a zircon which is 4,404 million years ± 8 million years which is in a metamorphic gneiss in the Jack Hills of the Narryer Gneiss Terrane of Western Australia.
What are facts about igneous?
.The oldest rock known today is the Igneous rock. .Igneous rock can be any colour..The word "Igneous" is a Greek word that means fire. Igneous rocks are formed by the cooling of molten rock, lava or magma. When magma solidifies in the earth they are intrusive, when lava cools outside the earth it is extrusive.
Which is the oldest rock sandstone or shale?
shale is metamorphic, which means time, pressure and temperature has altered it. Sandstone is sedimentary which means it was formed under water. generally sandstone is younder.
