Chronostratigraphy crash course

"golden spikes" = measurable markers between strata

Deuterium concentration

Strata also defined by fossils (biostratigraphy)

Summary: Chronostratigraphy

  • sedimentation & strata formation influenced by local factors but also by global events
  • measurable golden spikes needed to define geological time units
  • current epoch: Holocene (since last ice age)

is

shaped by biogeochemistry

not

a time of human control

The Anthropocene

[T]he present time interval, in which many geologically significant conditions and processes are profoundly altered by human activities [… which] have a decisive influence on the state, dynamics and future of the Earth system.

Not yet!

Erm, yes.

Will be proposed.

Summary

Accidentally? No!

You just begin. You do the math.
You solve one problem, then the next.

Thanks for your attention!

Questions?

When something influences sedimentation & strata formation globally, and future geologist agree on the next 'golden spike'.

Could be millennia.
