A STATISTICAL EXAMINATION OF THE EUROPEAN LITHOSPHERE-ASTNEHOSPHERE BOUNDARY FROM COMPARING SEISMOLOGICAL AND ELECTROMAGNETIC OBSERVATIONS

the lithosphere -asthenosphere boundary LAB is a fundamental boundary in the plate tectonic paradigm defined initially on the basis of the mechanical response of the earth to loading its usage has become ubiquitous across the geosciences but the natural difference in its definition due to differences in thermal physical and chemical parameters cause confusion.
