Peach
Tree Rock Preserve Field Trip
Columbia/South Carolina
Introduction
The Sedimentology
and Stratigraphy Basins (GEOL 325) class field trip to Peach Tree
Preserve close to Columbia in South Carolina. This Preserve is owned
and managed by the is owned by the South Carolina Nature Conservancy.
The sandy outcrops exposed in this Preserve accumulated in the middle
Eocene and were deposited when the sea level was about 125 meter
higher than the present . The outcrops at the Peachtree Rock Preserve
are now about 500' above sea level and represent an exposure which
is about 3-10 meters high.

sands outcropping in Peach Tree Park Preserve in Lexington County
just west of Columbia Metropolitan Airport.

Deliverables
1) Field
notes
2) A
measured section
a) Include
paleocurrent measurements
b) Identify at least 3 different facies you observed
–
Each facies should have:
a) Name
b) Description
c) Interpretation
3) A detailed description
of Peachtree Rock – the hoodoo block
a) Texture and grain
size
b) Sorting
c) Bedding
d) Lithologic composition
4) Short paragraph
of the depositional environment. Remember, marshal you argument
so that your interpretation fits the data.
Useful Links
for this exercise
To aid in your write
up you might want to the visit the terminology page and look under
parasequence-shoreline.  Also
check the four examples that Van Wagoner et al (1990) provided
for coarsening upward parasequences for a beach;
delta;
stacked
beaches ; and fining upward
stacked tidal flats in the terminology section of this site.
Also you might want to search with Google and under the images
search look for sedimentary structures like Hummocky Cross beds.
