What Lithoen records

Each claim states how it is known and cites its evidence.

Established2,050 Ma before present

The USGS stratiform chromite model dates the emplacement of the Bushveld Complex into the Kaapvaal craton to about 2.05 billion years ago.

Not stated verbatim by the source — derived: 2.05 Ga x 1000 Ma/Ga = 2050 Ma

The report gives the age in billions of years; Lithoen stores geologic ages in Ma. The conversion is exact and the "about" the report attaches to the figure is carried in the claim.

  • method: Geochronology as reported by the USGS deposit model, which gives the age as approximate and does not state the method or the uncertainty.
  • precision note: An age for the event as the source gives it. What exactly was dated — the whole body, one phase of it, one mineral — is not stated, and Lithoen does not supply an answer.

Evidence support: Derived from the cited evidence one source
