With the aid of polarity determinations, palynology, and radiogenic dating, the paleomagnetic results allow for new constraints on the emplacement age of the selected ultramafic occurrences.
The paleomagnetic emplacement ages established for the K5, K6, and Mountain Lake bodies aie 90-83 Ma, 83.0-79.1 Ma, and not older than 79.1 Ma, respectively.
On the earth's surface, when you hold a compass and the needle points to north, it is actually pointing to magnetic north, not geographic (true) north.
The Earth's magnetic north pole can change in orientation (from north to south and south to north), and has many times over the millions of years that this planet has existed.
By studying magnetizations of varying age from a single lithospheric plate, one can construct a path of apparent polar wandering (APWP) that tracks the motion of that plate relative to the geographic pole.
A well-defined APWP can serve as a geochronological tool, i.e., for dating magnetizations of unknown age through a comparison of their directions with those expected from the reference APWP.
Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.
A few examples of such lies are presented at the very bottom of this page.
Due to the vast amount of economic interest diamonds have created in northern Alberta, there is a need to produce an accurate geological model for the northern Alberta kimberlite province.However, human beings love to see factual precision, and we want to know how old something is.Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.Paleomagnetism is the study of the Earth’s ancient magnetic field through the record of remanent magnetism preserved in rocks.The directions of remanent magnetization are used to deduce the position of the Earth’s magnetic pole relative to the study location at the time when this magnetization was acquired.
