terms:sawtooth_sp
When a very permeable salt-water sand containing shaly streaks is invaded by fresh mud filtrate, the filtrate and saline interstitial solutions tend to separate because of the difference between their specific gravities. As a result, the filtrate tends to accumulate just below the shaly streaks setting up an electrochemical cell which causes the SP to develop a sawtooth appearance.
