Geosonnet 65

Speed dating is a scattershot affair
Which blasts the hearts of river zircon grains
No magic mirror can discern the fair
And youngest zircon sediment contains.
If dating based on chemistry is used
The youngest grain is easier to find.
But chemistry is tedious! Abused
Statistics can be questioned and refined.
The youngest kernel density’s a crone
The youngest single grain is way too young,
Statistical young grouping’s in the zone
Though less exacting than the dates Tims’s brung
So settle down, this zircon dating’s docile
Until you try to match it with a fossil.
