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.

Compliance Criteria

LEVEL 1

Criteria for a LEVEL 1 GeMS database are: Databases with a variety of schema may meet these criteria. This script cannot confirm LEVEL 1 compliance.

9 Qal Alluvium Alluvium Holocene Flood plain sands, silts, clays, and quartz gravels. Thickness is variable and, is dependent upon the size of the associated stream; thickest, up to 45 feet, along the Pearl River flood plain. Minor quartz gravel is present along the active channel of the Pearl River in Section 3, 4, and 9, Township 6 North,Range 2 East. Silicified wood common. 1-1-3 DMUUnit1 --- Qal 255,255,179 --- DAS1 Alluvial sediment, mostly fine-grained High DMU05

15 Ql Loess Loess Pleistocene Silt, buff to tan, pale yellow, red, or gray. Loess represented in this quadrangle is highly weathered, leached, noncalcareous and clayey; also referred to as brown loam. Loess deposits unconformably blanket the underlying units west of the Pearl River. 1-2-1 DMUUnit1 --- Ql --- Hollow Green (38,115,0) Circles overlay all older units DAS1 Loess High DMU07
20 Qth High Terrace High Terrace Pleistocene Sand, yellowish brown to reddish brown, fine- to medium-grained, silty to clayey, locally contains silicified wood and logs, commonly exhibits a coarsening downward fluvial sequence, with rip-up clay clast conglomeratenear unconformable basal contact with the Yazoo Clay. Predominantly associated with the Pearl River drainage system and confluences of itstributaries. Terrace thickness is variable from approximately 1 foot up to30 feet. 1-2-2 DMUUnit1 --- Qth 255,255,128 --- DAS1 Alluvial sediment, mostly fine-grained High DMU08

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