this file is a summary of 1D models for global crustal model CRUST 5.1.
there are three tables. the first one lists the global average,
the second one the average for continents (incl. cont. shelves),
and the third one is the average for oceans (incl. cont. slopes).
the averages are true equal area averages (not averages of the
5x5 degree cells of CRUST5.1).
CRUST 5.1 consists of 7 layers: water, ice, soft sediments, hard
sediments and a three-layer crystalline crust (upper, middle, lower).
the last line are the parameters of the upper mantle immediately
below the moho (thickness 999. indicates the halfspace).

IMPORTANT NOTE for CRUST5.1 users:

In CRUST5.1, the first layer is ice and the second layer
is water (so the layers are flipped here)!!
