2. MINERAL DEPOSITS ALONG
PLATE BOUNDARIS
 Mineral deposits are usually located in
tectonic plate boundaries due to the
shifting of the plates.
 The majority of mineral resources tied to
plate tectonics are either directly or
indirectly to volcanic activity.
 The boundaries between tectonic plates
are extremely dynamic places.
 Volcanoes, earthquakes,mountains are
important mineral deposits.

3. Different kinds of plate
boundaries
DIVERGENT BOUNDARIES
Divergent boundaries are where two plates are moving
away from each other and are mostly located under
oceans.
CONVERGENT BOUNDARIES
Convergent boundaries are where two plates are moving
towards one another.
TRANSFORM BOUNDARIES
Transform boundaries are where two plates are moving
laterally past one another. The San Andreas fault in
California is the best example.

4. MINERALISATION AND
PLATE BOUNDARIES
 The energy released along boundaries results in
volcanic and hydrothermal activity that creates the
minerals to be concentrated.
 Plate boundaries are also a way for deep seated rocks
from the mantle to the near surface.
 One oceanic plate is being forced progressively under
another plate it creates both heat and minerals are
wide variety of mineral deposits.

6. Limitations of plate tectonic theory
 The theory of plate tectonics is together
continental drift and seafloor spreading.
Plates are made of lithosphere topped
with oceanic and continental crust.
 The plates are moved around on earth’s
surface by seafloor spreading.
 Oceanic crust is created at mid ocean
ridges. The crust moves outward from the
ridge over time. The crust may eventually
sink into the mantle and be destroyed.

7. • The theory of plate tectonics brings together
continental drift and seafloor spreading.
• At a plate boundary, two plates can be
moving apart, together or past each other.
• Plate tectonics theory explains many things
in geology, such as volcanoes, ore deposits,
and other features are located.
