Inspection of drill cuttings indicated that the
Arcadia Formation is often present within
five meters of the surface in the vicinity of
southern Longboat Key and northern Siesta
Key. It should be noted that much of Lido
Key and Bird Key were artificially
constructed from surrounding dredged
material (Slattery, et al., 1914). Therefore,
the true top of Tha in this area is uncertain.

beneath the undifferentiated Tertiary/
Quaternary fossiliferous sediments and the
undifferentiated Quaternary sediments. It is
commonly present within 20 feet (6.5
meters) of the surface near the southern
edge of the De Soto Plain. It is also present
in a small area west of Lake Manatee and
east of Interstate 75, near the northern edge
of the study area. The Peace River

The surficial sediments and soils of the
western portion of the U.S.G.S. 1:100,000
scale Sarasota Quadrangle are moderately
variable in their makeup. End-member
lithologies of sediments in the study area
include quartz sand, silt, clay, and organic
material.
For the purposes of this map, surficial
sediment types were determined by
examining material from within the upper
two meters of the land surface. Data
utilized in creating this map came from a
variety of sources, including the United
States Department of Agriculture
(U.S.D.A.) soil surveys of Manatee,
Sarasota, and Charlotte Counties (Hyde
and Huckle, 1983; Hyde, et al., 1991; and
Henderson, 1984), hand-augered samples,
surficial samples, well cuttings, and cores.
Over 50 different soil classifications
were identified for the Sarasota quadrangle
in the U.S.D.A. soil surveys for Manatee,
Sarasota, and Charlotte Counties. For the
purposes of this map, these soil types were
combined into six units. These units are
based on the lithologies of the constituent
components of the soil types and did not
take into account factors such as moisture
content and plasticity. For more detailed
information on soil types in the area, the
reader should refer to the U.S.D.A. Soil
Surveys for Manatee, Sarasota and
Charlotte Counties (see Hyde and Huckle,
1983; Hyde et al., 1991; and Henderson,
1984, respectively)
The predominant constituent of the
surficial sediments throughout the
quadrangle is quartz sand. This is most
evident in the northeastern part of the
study area, where elevations are relatively
high, and the undifferentiated Quaternary
(Qu) sediments are thickest (see
accompanying geologic map). All of the
sediment types shown on this map contain
at least some quartz sand. In some areas,
the unit mapped as sand contains minor
shell material. Although much of the area
mapped as Tertiary/Quaternary
undifferentiated fossiliferous sediments
(TQsu) on the accompanying geologic map
does contain significant amounts of shell
material, it was generally deeper than two
meters below the land surface.
The next most common sediment type
in the study area is loam. Loam, which is
defined as "soil material that is 7 to 27
percent clay particles, 28 to 50 percent silt
particles, and less than 52 percent sand
particles" (Hyde, et al., 1991, p. 97.),
occurs throughout much of the map area,
particularly in drainage features and basins.
Occurrences of loam are most prevalent in
areas where the Qu is relatively thin (see
geologic map).
The remaining units depicted on this
map: sand/loam, clay/sand/loam, muck,
and sand/rock, are relatively minor in areal
extent. Mixtures of sand and loam are
most prevalent in the southern part of the
study area. Clayey sediments, with
admixtures of sand and loam, are present
near the southern Myakka River basin.
Muck, soil material which contains slowly
decaying organic matter and may contain
some silt and clay, is present around the
Myakka River basin, the Braden River
basin, and in other areas where drainage is
poor. The unit mapped as sand/rock
generally coincides with areas where the
Arcadia Formation is within a few meters
of the land surface, such as around the
Braden River and Bradenton.
