Currently the oldest insitu rock layers of terrestrial origin were discovered by Dr. Jonathan O'Neil and his colleagues, whose work published in September of 2008, revealed rocks as old as 4.28 billion years of age in Northern Quebec, along the Hudson's Bay coast, 40 km south of Inukjuak. This area is known as the Nuvvuagittuq greenstone belt. They were dated by measuring the decay of the element neodymium-142 which was present in the rock.
However this is either the oldest rock material of Earth origin or the oldest rock material found on Earth.

What else can I help you with?
What physical characteristic of the bedrock responsible for oldest rock?
The physical characteristic of bedrock responsible for the oldest rock is its age. The oldest rock forms the foundation of the Earth's crust and is composed of minerals that have remained relatively unchanged for billions of years. This bedrock provides valuable information about the early history of our planet.
Why must the earth be older than its oldest rocks?
Two points here: rocks are solidified material--early Earth was molten. The first rocks appeared after the molten Earth cooled somewhat. Secondly, Earth's rocks are constantly being recycled through the 'rock cycle'. The oldest rocks on Earth have somehow survived those recycling efforts, but no rock found on Earth (other than some meteorites) is as old as the planet.
The rock at the bottom of an undisturbed sequence is?
The bottom is oldest. The top is newest. -From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.
What is the oldest known mineral on earth?
The oldest terrestrial material discovered on Earth to date is a zircon crystal found in Western Australia within a metamorphic gneiss which was part of the Narryer Gneiss Terrane. It has been dated at 4.404 Ga (4.404 billion years old). Please see the related link for more information. For information on the oldest rock on Earth, and the oldest rock mass of terrestrial origin, please see the related question.
How old is the oldest rock ever found?
The oldest rock of terrestrial origin (i.e. the whole rock was formed here on Earth at the same time) is the Nuvvuagittuq greenstone in Canada. It has been dates as 4.28 billion years old. The oldest single thing yet found that is known to have been formed on Earth is a zircon crystal which was located in Western Australia within a metamorphic gneiss which was part of the Narryer Gneiss Terrane. It has been dated at 4.404 Ga (4.404 billion years old) however the rock it is in is younger than this. The oldest rock ever found on Earth is actually a meteorite so was not formed here. It is estimated to have an age of around 4.56 billion years so is roughly the same age as the Earth.
What is the oldest rock in earth?
Igneous Rock
Crystals in rock thought to be part of the oldest crust on earth?
They are zircon crystals.
In what country are the oldest rocks on Earth?
The oldest in-situ rock found on Earth to date was found in Northern Quebec in Canada and is dated as 4.28 billion years of age.
Is granite the oldest rock in the world?
No, granite is not the oldest rock in the world. Some of the oldest rocks on Earth are found in Western Australia and are over 4 billion years old, while granite typically ranges from 300 million to 3 billion years old.

The oldest rock is what kind of rock?
what kind of rock is the oldest rock
Why are the oldest rocks found on earth younger than the oldest lunar rock that Apollo brought back?
The Earth has lots of tectonic activity, by which I mean earthquakes and volcanoes, which the moon does not have. Rocks can survive longer on the moon.
Are the oldest rocks on Earth in the Grand Canyon?
No, the oldest rocks on Earth are not located in the Grand Canyon. The oldest rocks found on Earth are estimated to be over 4 billion years old and are typically found in locations such as Canada, Australia, and Africa.

Which layer of rock is the oldest?
The basement is a term sometimes used, and Cratonis another used in a continental context.The Principle of Superposition has it that in a given formation, the top layers are the youngest, and the deeper layers the oldest.
Why must the earth be older than its oldest rocks?

Which rock layer is the oldest and why?
The oldest rock layer is typically found at the bottom of a sequence of sedimentary layers, following the principle of superposition in geology. This principle states that in an undisturbed sequence of rock layers, the oldest layer will be at the bottom and the youngest at the top. Therefore, the rock layer closest to the Earth's surface is usually the youngest, while the rock layer at the bottom is the oldest.
