This database is LEVEL 3 COMPLIANT.
The database-level FGDC metadata are formally correct although the metadata record should be reviewed to verify that it is meaningful.
This file should be accompanied by MS_2025_MageeNorth_1-1.gdb-ValidationErrors.html and MS_2025_MageeNorth_1-1.gdb-vFgdcMetadata.xml_errors.txt in the same directory.
If this database will be submitted to the NGMDB, it also needs to be accompanied by a reviewed Geologic Names report that includes identification of any suggested modifications to Geolex. Use the Geologic Names Check tool to generate that report or provide other documentation of a review.

Sand is gray, pale yellow to white; fine to coarse grained; cross bedded to massive. Contains rare thinly bedded pea gravel layers. Gravels consist of highly polished black chert and milky quartz, ranging from subangular to well rounded. Sand is commonly indurated near the surface to sandstone. Predominantly quartzose with lesser amounts of chert, metaquartzite, mica, and heavy minerals; slightly glauconitic in places. Silicified wood and fossil palm fragments are common. Clay is green, gray, and brown; weathers white to brown in color; silty to sandy. Lignite is common in basal clay intervals. Unit is fossiliferous in part. Limestone (Tatum Limestone Member) is characterized by the benthic foraminifera Heterostegina texana. Occurs in the subsurface within the Catahoula Formation. The Catahoula Formation unconformably overlies and locally incises into the underlying Bucatunna Formation.

14 | Tv | Vicksburg Formation | Vicksburg Formation | Oligocene | Includes the undifferentiated associated marine units, listed in descending stratigraphic order: Bucatunna Formation, Byram Formation, Glendon Formation, Marianna Formation; and Mint Springs Formation. The Bucatunna Formation consists of carbonaceous clays dark brown to gray in color, silty to fine sandy, averaging about 45 ft in thickness but reaching up to 60 ft within the mapping area. The Byram Formation is composed of sandy to clayey marl, glauconitic and fossiliferous, with a thickness of up to approximately 12 ft. The Glendon Formation consists of semi crystalline limestone interbedded with softer clayey marls and represents the marine highstand of the early Oligocene Vicksburg sequence. The underlying Marianna consists of soft clay marls. Collectively the Glendon-Marianna section reaches a maximum thickness of about 30 ft in the mapping area; The Mint Springs Formation consists of gray to green colored glauconitic and fossiliferous quartz sand. The Vicksburg Group is biostratigraphically characterized by the presence of Pecten byramensis and the larger benthic foraminifera Lepidocyclina sp. The Vicksburg Group unconformably overlies the Forest Hill Formation. | 2-3-1-2 | DMU Unit 1 | Tv | Tv | 168,0,0 | None | OF0359 | Mostly carbonate rock | High | DMU13
15 | Tfh | Forest Hill Formation | Forest Hill Formation | Oligocene | Deltaic sands, silts, and clays. Sand is fine-grained, silty, and quartzose; clay is carbonaceous and laminated, with lignite and silicified wood common. Carbonized plant fossils occur along fissile partings in clay intervals. The Forest Hill Formation unconformably overlies and commonly incises into the Yazoo Formation and represents the lowermost unit of the Vicksburg Group, distinguished from overlying units by its terrestrial to deltaic depositional setting.

Clay is calcareous and montmorillonitic, blue green when in color unweathered, sparingly fossiliferous marine mollusk shell hash common along partings and bentonite seams present. Limestone ledges occur in places. The Yazoo Clay reaches a thickness of approximately 515 ft. The Yazoo Formation is marked by the planktonic foraminifera Hantkenina alabamensis.

19 | Tmb | Moodys Branch Formation | Moodys Branch Formation | Eocene | The Moodys Branch Formation represents the basal member of a marine transgression towards the close of the Eocene epoch, situated unconformably above the deltaic to estuarine Cockfield Formation and conformably below the outer neritic to bathyal clays of the Yazoo Formation. It consists of sandy, fossiliferous marl containing abundant marine mollusk shells of the genera Glycymeris and Venericardia. The unit unconformably overlies the Cockfield Formation, reflecting the delta destructional phase and subsequent marine transgression, and it conformably grades upward into the Yazoo Formation. Total thickness is approximately 15 ft. | 2-4-1-2 | DMU Unit 1 | Tmb | Tmb | 171,107,79 | None | OF0359 | Marine sediment, mostly fine-grained | High | DMU18
