Clay minerals are very small, usually less than 4 µm in diameter, and have net negative sur-face charge (Brindley and Brown, 1980). Their high surface area and negative charge, providing large reaction surface and ion-exchange capacity, allow clay minerals to track relatively subtle changes in flu-id chemical composition.
