Tay Salt Marsh Sediment Fabrics
Abstract
Silts trapped within broken stems of the reed Phragmites communis form plugs which fall to the marsh floor as organic decay destroys the stem. The plugs form cylindrical plant-wrapped nodules within the sediments. Such structures have formerly been attributed to infilled roots, but the reed rhizomes of the Tay marshes collapse after death and are flattened, not flied.
