Streams on clay subcrop will exhibit shallow, wide alluvial plains while streams on sand subcrop tend to incise creating steep valleys with narrow alluvial plains, silicified wood common. Thickness approximately 15 feet along larger streams, thinning up tributaries. | 1-1-1 | DMU Unit 1 | Qal | Qal | 255,255,179 | None | OF0365 | Alluvial sediment, mostly fine-grained | High | DMU03 |

| 6 | Ql | Loess | Loess | Pleistocene | Silt, buff to tan, pale yellow, red, gray to gray-green where in anoxic conditions, quartzose to feldspathic. Loess is considered an eolian deposit derived from glacial outwash. Loess is typically calcareous with dolomite and calcite; however, the upper portion of the loess can be deeply weathered, leached / noncalcareous, and has been commonly referred to as "brown loam." Loess deposits unconformably blanket the pre-loess topography with substantial local variations in thickness but generally thickening towards the west. In places, weathered loess contains secondary deposits of small calcareous concretions such as caliche and loess dolls. Loess can be locally and sparingly fossiliferous, commonly containing tests or steinkerns of pulmonate gastropods and less commonly containing fossils of Pleistocene vertebrates. | 1-2-1 | DMU Unit 1 | Ql | Ql | None | Hollow cirlces of 38,115,0 | OF0365 | Loess | High | DMU06 |
| 7 | Qtpl | Pre-Loess Terrace Deposits | Pre-Loess Terrace Deposits | Pleistocene | Pleistocene ancestral Mississippi River terraces deposited prior to Pleistocene loessification. Sand, yellow, orange, purple, red, pink, fine- to coarse-grained, predominantly quartzose, cross-bedded to massive; graveliferous, pea to large cobble size clasts, boulder size ice-rafted clasts of sandstone and chert. Economically significant gravels are predominantly chert with lesser amounts of vein quartz, metaquartzite, agate, sandstone, and rare rhyolite clasts; clay, pink to white, generally occurring as discontinuous lenses and as rip-up clasts up to boulder-size. Conglomeratic ironstone ledges are common in the graveliferous sands at the base of the deposits. The base of this terrace occurs at approximately 250 ft MSL and is masked by about 40 ft of loess overburden. | 1-2-2 | DMU Unit 1 | Qtpl | Qtpl | 255,214,230 | None | OF0365 | Alluvial sediment, mostly coarse-grained | Medium | DMU07 |

| 11 | Ty | Yazoo Formation | Yazoo Formation | Eocene | Outer neritic to bathyal marine clay. Clay is calcareous and montmorillonitic, blue- green when unweathered. Sparingly fossiliferous, with marine mollusk shell hash common along partings. Bentonite seams present. Limestone ledges occur in places. The Yazoo Formation is marked by the planktonic foraminifera Hantkenina alabamensis. The Yazoo Formation conformably overlies the Moodys Branch Formation. Total thickness is approximately 400 ft. | 2-1-1-1 | DMU Unit 1 | Ty | Ty | 255,204,0 | None | OF0365 | Marine sediment, mostly fine-grained | High | DMU11 |
| 12 | Tmb | Moodys Branch Formation | Moodys Branch Formation | Eocene | The Moodys Branch Formation is the basal member of a marine transgression towards the close of the Eocene epoch in the northern Gulf, 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. | 2-1-1-2 | DMU Unit 1 | Tmb | Tmb | 171,107,79 | None | OF0365 | Marine sediment, mostly fine-grained | High | DMU12 |

Clays are gray to brown in color, silty to fine sandy, plastic, highly carbonaceous with thin beds of lignite common, slightly micaceous, and locally pyritic. Sands are quartzose and are cross bedded to massive, locally lignitic, and can be silty to clayey. Conformably overlies the Cook Mountain Formation. Thickness is approximately 400 feet. | 2-1-2-1 | DMU Unit 1 | Tco | Tco | 237,222,130 | None | OF0365 | Sandstone and mudstone | Medium | DMU14 |
