This file should be accompanied by MadisoninGeMS.gdb-ValidationErrors.html, MadisoninGeMS.gdb-vFgdcMetadata.txt, and MadisoninGeMS.gdb-vFgdcMetadataErrors.txt, all in the same directory.

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.

LEVEL 1

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

Predominantly associated with the Pearl River drainage system and confluences of itstributaries.

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.	2-2-1	DMUUnit1	---	Ty	255,204,0	---	DAS1	Mostly mudstone	Low	DMU11
