Abstract:

By controlled experiments that simulate marine conditions, it is shown that accelerated weathering and mineral authigenesis occur during the combined process of digestion, ingestion and excretion of sediment by worms. Previously characterized synthetic mud, composed of finely ground, low-grade metamorphic slate dominated by highly crystalline chlorite and muscovite, was unchanged in control tanks over a 20 week time scale, but was significantly different in faecal samples from an ...
