Precambrian (>540 Mya) and Phanerozoic (<540 Mya) crustal basement. Archean cratons are shown in red. Cratons are
labeled as follows: 1, Slave; 2, Wyoming; 3, Superior; 4, Greenland; 5, Fennoscandian; 6, Siberian; 7, North China; 8, west Australian;
9, Indian; 10, Tarim; 11, Tanzanian; 12, South African (Kaapvaal); 13, Congo; 14, west African; 15, Amazonia; 16, Colorado Plateau.
Modified from Goodwin (1991) and Pearson & Wittig (2008).

“freezes” in the original 187 Os/188 Os of the rock, which can be used to calculate a model age for
separation from the convecting mantle. The compatibility of Os also ensures that most metaso-
matizing agents (melts or fluids) are highly depleted in Os; hence disturbance by metasomatism
CRATONS
´Old stable parts of Continental crust that has
survived the merging and splitting of continents
and supercontinents for at least 500 MY.
´Differentiated parts of the continental
lithosphere with one or more Archaean nuclei,
exhibiting thick lithospheric mantle roots
´Found in the Continental Interior
´Comprises of Felsic igneous rocks (granite)
attached with Upper Mantle
´May extend ~200 -700 Km (root of cratons)
CRATONS…..
´Subdivided into Geological provinces
´Geological Provinces Classified as:
´Archon (Archaean Era: > 2500 MY)
´Proton (Early-Middle Proterozoic era: >1600 MY)
´Bacteria, fungi, Primitive multicellular organism
´Tecton (Proterozoic era: 1600-800 MY)
´Bacteria, fungi, Primitive multicellular organism
