LABORATORY 3 – PLATE ROTATIONS
OBJECTIVES: Use evidence of sea floor spreading recorded in
Marine Magnetic
Anomalies to determine the current plate motions for Atlantic
Bordering Plates
(North America, Eurasia, Africa, South America). Using these
results, determine the
nature of the boundary separating the North America and South
America plates.
BACKGROUND: The sea-floor of the Atlantic has recorded, via

10. magnetic anomalies,
the relative motion of NA/EU, NA/AF, and SA/AF. Using that
data we can determine
the relative motion of each of those plate pairs. The age of
anomalies used to
calculate these motions will constrain the time interval over
which that plate motion
is operable.
Using a global map of magnetic anomalies we can determine the
local relative
motions (near the ridge) and using that information determine
the relevant Euler
Pole. Following Euler’s Fixed Point Theorem, we know that
relative motions between
these plate pairs will fall along small circles to the rotation
pole, and thus will be
perpendicular to great circles between the measurement location
and the rotation
pole.
Using the Spreadsheet Vel_Azimuth you can test orientations
and rates of relative
plate motions at specific locations along the plate boundary (or
elsewhere). The
spreadsheet is available on-line. In Part 1 below you can test a
known rotation pole
against your observations. In Part 2 you are asked to use your
observations to
determine an acceptable rotation pole. In Part 3 you will use
your results to
determine SA/NA Plate Motion.

11. EXERCISE:
PART 1: WHICH ROTATION POLE IS BEST?
Various poles of rotation have been determined for the NA/EU
and the NA/AF plate
motions. For the first part of this lab you should use data
(direction and velocity)
obtained from the relevant sections of the Mid-Atlantic Ridge to
assess the
goodness of fit for the published poles.

NA/AF
PART 2: WHAT IS THE EULER POLE FOR SOUTH
AMERICA AND AFRICA?
Using Magnetic Anomalies from the southern Atlantic Ocean,
determine a best-fitting
Euler pole to describe SA/AF motions. You should determine
the direction of motion
and the rate (cm/yr) of plate motion at a suite of locations along
the Mid-Atlantic

12. Ridge, using both your map and the globes (~ 10+ would be
ideal). With those data
and the spreadsheet (Vel_Azimuth) to calculate plate motions,
iterate to find the best
fitting rotation pole for SA/AF motions. Validate this location
using the globes.
PART 3: HOW DO NORTH AMERICA AND SOUTH
AMERICA INTERACT?
Knowing Euler Poles for the relative motion of North America
and South America
with respect to Africa, determine the Euler Rotation Pole that
describes the motion
of North America with South America. Using that pole and your
analysis of likely
locations for the plate boundary (or plate boundary zone)
between these two plates,
