heal.abstract	The paper describes two unusual lithologies that occur in a sequence of Mg-rich lacustrine sediments in northern Greece. The first is a laminated mudstone in which layers composed of magnesian smectite alternate with layers composed of an amorphous clay of similar chemical composition. The second lithology is a thin bed of mudstone in which the only crystalline constituent is hydrotalcite (a magnesium aluminum hydroxide), accompanied by amorphous high-magnesium clay. Hydrotalcite has not previously been recorded from sedimentary rocks except as a product of industrial pollution. The high-magnesium clay is considered to have formed by precipitation from Mg rich lake water onto volcanic ash particles, whilst the hydrotalcite has filled the molds left by dissolution of volcanic glass within the clay-coated particles.	en
