The process of nuclear division which creates two new identical nuclei is called

Mitose

Explanation:

Mitosis is a type of cell division that occurs in all eukaryotic cells and ensures the formation of two daughter cells with identified nuclei. It is an important process for the growth and regeneration of multicellular organisms and for asexual reproduction of unicellular organisms.

Despite being a continuous process, mitosis can be divided into four distinct phases: prophase, metaphase, anaphase and telophase. This process begins after the interphase period, which comprises the time between two phases of cell division.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
