Burial
by Gabe Reitzes
Sedimentary rocks are formed
when sediment
a naturally occurring material
broken down
by processes of
weathering, erosion
Deposited out of air,
ice, wind, gravity,
and water flows,
carrying the particles
in suspension.
Everything will be buried eventually.
Ships sunken, bones
broken or in tact,
butterfly wings
and cow pies
lose definition,
in time.
As sediments accumulate in a depositional environment,
older sediments are buried by the younger, and
undergo diagenesis
includes all the chemical,
physical, and biological changes
exclusive of surface weathering
undergone.
Under, gone.
Compaction
Lithification
a deeper burial takes place.
Texture
flavor
smell
will not survive the process.
The mineral dissolved from
strained contact points is
redeposited in the unstrained
pore spaces.
Pressure solution—
This further reduces porosity
and makes the rock more
compact, competent.
Heat, pressure, time
Mud, silt, detritus
At sufficiently high temperature and pressure,
the realm of diagenesis makes way
for metamorphism
transformation
of existing rock to a rock
with different mineral composition
or texture.
The rock remains
mostly solid.
