Radiometric dating of detrital minerals in sedimentary rocks gives
The elliptical depression to the left is the Searles Lake basin, the smaller linear valley is Panamint Valley and the larger one is Death Valley.
The mountain range between Death and Panamint valleys is the Panamint Range and the Black Mountains bound the other side of Death Valley.
Thus, sedimentary and metamorphic rocks can't be radiometrically dated.
The problem : By the mid 19th century it was obvious that Earth was much older than ..
Dating the particles which make up the rock wouldn’t give you the age of the rock itself.
Sedimentary rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets.
