As was pointed out in the earlier article on potassium-argon dating, Brent Dalyrmple, a leading researcher in radioactive dating
and, incidentally, a very active supporter of evolution in the debates ongoing in the US, has likened the argon that is formed in a mica mineral to that of a bird in a cage.
of minerals in the clinker outcrops suggests that some of the region's coal fires occurred as many as 2.
shows that those gems formed about 2.
of the melts and the hydrothermal deposits indicates the Sudbury impact occurred about 1.
shows that the mites were entombed roughly between 3,200 and 800 years ago, Polyak notes.
Astronomers have determined the age of many stars using radioactive dating
Scientists later used radioactive dating
to determine the ages of layers of the lava and ash that have repeatedly blanketed the area.
The researchers relied on radioactive dating
to determine the ages of tiny glass beads in the soil samples.
