Formation of Load Casts
Density of sand unit > densityof mud unit
2 cm
2 cm
Denser sand sinks down
into the mud due to theforce of gravity and the
greater density, forming a
load cast. The sand may
separate completely and
form a blob in the mud.

Formation of Flute Casts
A turbulent water current, often foundin the deep sea, flows over mud.
cause erosion of the mud to take place.
As the velocity of the
current decreases,
sediments aredeposited in the
mould, forming the
flute casts.
