Thus, dating each mineral grain only gives the age of the source rock that was eroded, to produce that sand, from which the zircon grain is derived. The 5 grains yield ages of 160, 110, 2020, 66, and 162 million years. What do these ages tell you about the age of the sedimentary strata? A) They are Precambrian rocks, older than 2020 million years.

A fossil is as useful as it gets if the sediments where it has been found can be identified and recorded. The sediments in the Turkana basin have been "sandwiched" within a series of volcanic tuffs. A tuff is a layer of volcanic ash made up of volcanic glass that is deposited after an eruption and eventually forms a sedimentary rock.
