Is Feldspar Rock Magnetic

The continued development of highly sensitive squid magnetometers has opened the way for paleomagnetic and paleointensity studies of individual rock forming miner- als. the motivation for these studies is the desire to avoid contamination of magnetic data related to secondary minerals that commonly form in the ground mass of igneous rocks on geologic timescales or during.
