The location and age of the oldest rocks is a movable feast, depending on the state of geological exploration, and the particular part of the sample dated.
Having said that, these rocks are gneiss and zircons in them are often the material dated.
Naturally, we have no access to rocks subsequently overrun by basalt shields and similar concealment.
The dates are in the vicinity of 4.4x109 years ago, (+/_8 Ma). Specific locations include the Canadian Shield, and the Jack hills of Western Australia.

Why are the oldest rocks found in Iceland?
The oldest rocks in Iceland are found because of its location over the Mid-Atlantic Ridge, where new oceanic crust is continually formed. As a result, the rocks at Iceland's boundary represent some of the oldest on Earth as they have not been subjected to the intense tectonic activity and recycling that typically occurs at plate boundaries.

Studying these rocks provides valuable insights into the early history of the moon and the solar system.
