Development of Magnetic Susceptibility Instrumentation and Applications (2015)
DOCUMENT
Citation Only
A 1997 NCPTT grant to develop a prototype down-hole magnetic susceptibility instrument arose out of frustration with existing technology and a desire to expand archeological field studies of magnetic susceptibility. This instrument allowed high-resolution vertical investigations of susceptibility within a small diameter (ca. 2.5 cm) hole made with a push-tube corer. An NSF grant supported improvement of the prototype via robust laboratory and field testing, resulting in a final engineered...
