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)

shaped by biogeochemistry

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.

Erm, yes.
Will be proposed.

Accidentally? No!

You just begin. You do the math.
You solve one problem, then the next.
Thanks for your attention!
Thanks to the Congress organisers, thanks to the angels!
Questions?
When something influences sedimentation & strata formation globally, and future geologist agree on the next 'golden spike'.
Could be millennia.
