This database is
LEVEL 3 COMPLIANT, pending completion of a peer-reviewed Geologic Names report that includes identification of any suggested modifications to
Geolex.
The database-level FGDC metadata are formally correct. The
metadata record should be examined by a human to verify that it is meaningful.

Compliance Criteria
Criteria for a LEVEL 1 GeMS database are:
- No overlaps or internal gaps in map-unit polygon layer
- Contacts and faults in single feature class
- Map-unit polygon boundaries are covered by contacts and faults lines
Databases with a variety of schema may meet these criteria. This script cannot confirm LEVEL 1 compliance.
A LEVEL 2 GeMS database is accompanied by a peer-reviewed Geologic Names report, including identification of suggested modifications to Geolex, and meets the following criteria:
2.1 Has required elements: nonspatial tables DataSources, DescriptionOfMapUnits, GeoMaterialDict; feature dataset GeologicMap with feature classes ContactsAndFaults and MapUnitPolys |
PASS |
2.2 Required fields within required elements are present and correctly defined |

Yazoo Formation |
Yazoo Formation |
Eocene |
Clay, bluish-green to bluish gray, weathers yellowish brown to tan, montmorillonitic, calcareous, silty, locally fossiliferous, locally contains, framboidal pyrite. Weathered sections commonly exhibit selenite gypsum, jarosite, and weathered pyrite in the form of limonite. Due to its high shrink -swell potential, the Yazoo Clay poses a high-risk for engineering andconstruction projects. A typical marine shell bed is visible along the east bankof Pearl River in (SE 1/4, SE 1/4, Section 3, Township 6 North, Range 2 East.Total thickness is approximately 450 feet, however, the maximum thicknessin the quadrangle is approximately 380 feet in the southeast portion of the quadrangle. |

Identity of a feature cannot be determined using relevant observations and scientific judgment; therefore, one cannot be reasonably confident in the credibility of this interpretation. For example, IdentityConfidence = questionable is appropriate when a geologist reasons "I can see some kind of planar feature that separates map units in this outcrop, but I cannot be certain if it is a contact or a fault." |
