AGEMark Meyer has created a
timeline for the presence of amber within the
geologic time scale.
Briefly, the oldest amber has been found is of Carboniferous period (360-285
million years ago). Both the Baltic and Dominican Amber is of Tertiary period
(65-2 million years ago). Baltic Amber is of
55-40 million years
old, while Dominican Amber is about
30 - 20
million of years. Younger so-called amber of 25 - 2 million years old , probably
copal. Resins that
have been dated to a few million years old or less are surely copal.
A capsule of oxides encrust the chunk of Baltic Amber,
Amber that is buried in the ground is well
protected from oxidation, but exposed amber gets into contact with oxygen and
encrusts with a capsule of oxides over a long time. Areas full of heavy
sediments such as clay and sand are ideal natural amber storages. Baltic Amber
is well preserved in a geological strata called "blue earth".
