Summary:

Magnetic methods for determining the grain size of magnetite were based on an understanding of a magnetic domain state where theories of rock magnetism distinguished three magnetic domain states: single domain (SD), pseudo-single domain (PSD), and multidomain (MD). This document describes a new rapid method for identifying relative grain size variations in magnetite that involves the parameter anhysteretic susceptibility which was particularly sensitive to the SD and PSD trains of the finer magnetite fraction. This study was done following a drought that occurred during the period 1977-1978 that resulted in a roughly fourfold reduction in the volume of Lake Waiau, a small perched body of water near the summit of a volcano in Hawaii.
