Which Rock Is The Oldest And Why. First, are we talking about the oldest identifiable mineral grain (zircons, about 4.4 billion years old), or the oldest complete rock (isua greenstone belt, greenland, 3.8 billion. The relative age of a rock is its age in comparison with other rocks. The oldest whole rocks found so far. Nasa in the public domain. Determining the relative ages of rocks. Some of these rocks have sm/nd ages in excess of 4.0 ga and may be the oldest rocks on earth. At about 4.3 billion years old, bedrock in northeastern canada currently holds the title of oldest known rock on earth (sn: Look for the nearest active volcano. Some of the zircons (but not the surrounding rock) date back as far as 4.4 billion years, making them the oldest traces of geologic history ever found. In western australia, scientists have found zircon. The oldest rocks on earth can be very difficult to find and verify, but the youngest rocks are easy to locate: If you know the relative ages of two rock layers, you know which is older and which is younger, but you do not know how old the layers are in years.
