-
A.
Global Boundary Stratotype Section and Point
chosen
The Global Boundary Stratotype Section and Point (GSSP) is an internationally agreed reference point in a specific rock sequence that precisely defines the lower boundary of a stage or age in the geologic time scale.
-
B.
Global Boundary Stratotype Section and Point for base of Hettangian
The Global Boundary Stratotype Section and Point for the base of the Hettangian is the internationally agreed geological reference point that marks the formal beginning of the Jurassic Period and the Mesozoic era’s post-Triassic recovery interval.
-
C.
Global Boundary Stratotype Section and Point for the base of the Anisian
The Global Boundary Stratotype Section and Point for the base of the Anisian is the internationally agreed geological reference point that marks the beginning of the Anisian Stage and thus the formal onset of the Middle Triassic.
-
D.
Global Boundary Stratotype Section and Point at Klonk, Czech Republic
The Global Boundary Stratotype Section and Point at Klonk in the Czech Republic is a formally designated geological reference site that marks the internationally agreed base of the Devonian System and serves as a key standard for correlating Early Devonian rock strata worldwide.
-
