No, as even the oldest rocks of the Earth's crust have undergone at least some remelting since the first accretion of the planet.
Modern science usually uses various forms of radiometric dating (uranium-lead, potassium-argon and rubidium-strontium are the methods most commonly used for dating rocks) in an attempt to determine the age of minerals in the earth's crust.
However these will usually be used to find the date of crystallisation of a mineral. Many of the rocks forming the crust of the earth will have been remelted at some point during the geologic history of the early earth which effectively acts to reset the radiometric dating clock.
As such the oldest crustal rocks currently known have been dated as around 4.28 billion years of age in Northern Quebec, Canada, along the Hudson's Bay coast, 40 km south of Inukjuak.
And 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) although the rock itself is younger than this.
However the Earth is estimated to be 4.567 billion years old. These estimates come from chondritic meteorites found on Earth.

∙ 9y agoThe evidence is mainly from radioactive decay - measuring the ratio of different elements and isotopes. Do some reading on "radioactive dating" or "radiometric dating" for more details - for example, in the Wikipedia.

Why did James hutton reason that the earth is very old?
As Hutton made observations about the rocks in the area where he lived, he began to find clues that most changes on earth happen slowly, and that earth must therefore be very old.
Why are there rocks on the moon that are older than any rock on earth?
There is no geologic activity or weathering on the moon to break rocks down, so most of the rocks on the moon are nearly as old as the moon itself. Earth is geologically active and has processes that will destroy and recycle rocks. None of the rocks that made up Earth's original surface are still intact.
Radioisotope dating of moon rocks showed that the age of the oldest lunar rock was closest to how many years old?
Rocks from the moon have been dated to about 4.5 billion years old. The oldest earth rocks don't date that far back because the earth "reprocesses" rock, and the oldest rocks we know of on earth date back to about 3.7 to 3.8 billion years. The earth and moon formed at approximately the same time, as did the rest of the solar system.
Are the oldest rocks on Earth in the Grand Canyon?
Not hardly. The oldest rocks at the bottom of the Grand Canyon are around 2 billion years old. The oldest rock discovered on Earth of terrestrial origin is around 4.28 billion years old.
What type of resources are as old as earth?
Mineral reources,such as metals,ores,and some kind of rocks
When do astronomers blieve the solar system was formed?
By studying rocks from Earth, from the Moon and meteorites it is believed that the age of the Solar System is approximately 4.6 billion years old.
Why cant you find rocks 4.5 billion years old?
You can't find rocks 4.5 to 5 billion years ago because the earth was still so hot that it was still liquid and there were no rocks yet.
How old are rocks found in Apollo missions?
The moon rocks are older then the rocks found on earth.

Which would be least helpful to scientist trying to find evidence that earth is very old?
Examing contiental drift
How did Hutton get the name Father of Geology?
Before Hutton the church said that the earth was 6,000 years old,created on October 13th mid-afternoon but when Hutton,a Scottish farmer began studying rocks he came to a place called Sickly Point,where he discovered the earth must be atleast a few million years old,so he started the study of rocks,geology

What do geologists learn by studying the texture of igneous rocks?
they learn how long that rocs been there ,what encoutered it and how old it is
Why are the oldest rocks only millions of years old?
The premise is incorrect. Some rocks on Earth are billions of years old.
Some of the oldest rocks ever found have been estimated to be about 3.9 billion years old Is it likely that these rocks were present when Earth was first formed?
No. The fact that some of the oldest Earth rocks are over 4 billion years old indicates that Earth was in a molten state for around 300 million years. The first rocks would have formed on Earth from this molten material.
Why are there rocks on the moon that are older that any rocks on earth?
There is no geologic activity or weathering on the moon to break rocks down, so most of the rocks on the moon are nearly as old as the moon itself. Earth is geologically active and has processes that will destroy and recycle rocks. None of the rocks that made up Earth's original surface are still intact.
What is the current age of the earth?
The earth is roughly 4.5 billion years old. We know this to be the case because we have dated rocks from the moon that old, and earth must be at least as old as our moon.
