Short summary
The age of formation of buddingtonite, ammonium-bearing feldspar, can be dated with the Ar–Ar method; however, it may often give only minimum ages due to strong resetting. In the studied example it gives a Precambrian minimum age of fossils, associated with this occurrence, and the age of the accompanying mineral muscovite indicates an age near 1.5 Ga. We encourage more dating attempts of buddingtonite, which will give valuable information of diagenetic or hydrothermal events.
