Another factor causing a decreasing resistivity is the presence of iron minerals, particularly pyrite. The presence of pyrite will cause the density log reading to be higher than the matrix density (sand). This is due to the high density value of pyrite mineral of about 5.0 g cc-1 (Rider 2002et al 2001) which affects the low resistivity reading.
