Basic: Major Elements

The major elements are used to construct a basic vertical stratigraphy over the target zone. They represent building blocks of the main rock forming minerals and allow the client to see changes in stratigraphy before any significant processing of the data has occurred.  The minerals Al, K and Fe can also be used to help determine what type of clay minerals are present. Figure A displays data from an oil sands core from the McMurray Formation.
