The Florida Geologic Survey (FGS) maintains collections of well and surface outcrop samples. The well sample collection contains more
than 19,000 sets of samples from exploration, water, and oil wells. Most wells are represented by sets of drill cuttings. Approximately 1150
wells are represented by continuous core or core samples (a total of approximately 205,000 feet). The deepest continuous core in Florida,
2,707 feet, is housed in the FGS repository. The FGS, USGS, Water Management Districts, drillers and geologic consultants drill new core
and cuttings sample sets which are added to the archives. The sample repository facility occupies 12,090 square feet, with almost 35,000
cubic feet of shelf space, with room for expansion.
A collection of approximately 5,900 outcrop samples and mineral specimens is maintained by the FGS at its headquarters in the Gunter
Building, located on Florida State University’s Campus. These samples are cross-indexed by formation, lithology, county and location.
The collection is referred to as the "M-Series." The M-Series is particularly valuable given Florida's high rate of growth and
development. Surface exposures of critical lithologies have become inaccessible with the continued proliferation of roadways,
shopping centers, parking lots and high-rise housing. These sample archives and the FGS database are utilized by geologists at the
FGS, many other state, federal and local governmental agencies, universities (both in and out of the state), geological consultants,
well drillers and the public.
The FGS’s holdings also includes a collection of thin sections and geophysical logs. A complete listing of these items is available
In order to make arrangements to view our sample collection, please contact one of the geologists, assistant state geologist or the
acting director. A list of contacts can be found here in contacts. All requests to take samples
require advanced notice and approval. While we
are able to provide work space and microscopes, visitors are suggested to bring their own sampling materials such as: camera, sample
bags, markers, hand lenses, flash lights, brushes, hand picks, gloves, face mask for those who might be susceptible to mold and dust,
hand cleaner, etc.
If you are sending samples to the FGS please fill out and include a copy of our
well sample forms
The FGS is a participant in the National Geological and Geophysical Data Preservation Program
(NGGDPP). For more information about Geological sample preservation and repositories, see the brochure developed by the
