Some of the extensions to the GeMS schema identified here may be necessary to capture geologic content and are entirely appropriate. Please document these extensions in metadata for the database, any accompanying README file, and (if applicable) any transmittal letter that accompanies the dataset. Other extensions may be intermediate datasets, fields, or files that should be deleted before distribution of the database.

3	Qal	Alluvium	Alluvium	Quaternary	Sand, yellow- to brownish-white in color, fine- to coarse-grained, subrounded to rounded, predominately quartzose, locally graveliferous containing aggregate derived from the Pre-loess Terrace deposits, silty to clayey; humus lenses common; floodplain deposits are heavily loess-derived. Silicified wood common. Tributaries have narrow alluvial valleys and are deeply incised through the loess terrain. Thickness is interpreted to be approximately 10 feet with the exception of the Big Black River.	1-1-1	DMUUnit1	Qal	Qal	255,255,179	---	OF0329	Alluvial sediment, mostly fine-grained	High	DMU03
4	Qaf	Alluvial Fan	Alluvial Fan	Quaternary	Alternating silts, sands, and gravels deposited by streams entering the Mississippi River Alluvial Plain from the adjacent uplands. Coarsest at the apex of the fan, fining laterally (radially) from the apex of the fan. Alluvial fans interfinger with the Mississippi River Alluvium and are a significant source of recharge for the Mississippi River Alluvial Aquifer. Typically, the basal sand gravels of the Mississippi River alluvium beneath the alluvial fan can be recognized by the presence of numerous granite and metamorphic rock clasts.	1-1-2	DMUUnit1	Qaf	Qaf	255,255,179	Brown Speckled	OF0329	Alluvial sediment, mostly fine-grained	High	DMU04

Silicified wood common.

7	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 (caliche, 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	DMUUnit1	Ql	Ql	---	Hollow Green (38,115,0) Circles overlay all older units	OF0329	Loess	High	DMU07
8	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 220 ft MSL. "Head-of-hollow”, terrace-derived valley-fill deposits are common at lower elevations and are isolated to valley walls adjacent to the erosional remnants of the higher of the two terrace deposits. These deposits are of such limited extent as not to warrant representation on this map.	1-2-2	DMUUnit1	Qtpl	Qtpl	255,214,230	---	OF0329	Alluvial sediment, mostly coarse-grained	Low	DMU08

11	Tv	Vicksburg Group	Vicksburg Group	Oligocene	Includes the Bucatunna Formation, Byram Formation, Glendon Limestone, Marianna Limestone, and Mint Spring Formation. The Glendon Limestone is white to gray, commonly indurated to semi-crystalline bioclastic limestone, either massive or with alternating ledges separated by thinly-bedded glauconitic marl. The Glendon Limestone commonly contains solution cavities at or near outcrop. Larger cavities usually form at the contact with the underlying Marianna Limestone. The Marianna Limestone is white to pale-yellow, soft to indurated, glauconitic marl, containing an admixture of fine-grained sands and clays in places. There is an abundance of the large Foraminifera Lepidocyclina mantelli in the Marianna Limestone and Lepidocyclina supera in the Glendon Limestone and the echinoid Clypeaster rogersi. The Vicksburg Limestone unconformably overlies the Forest Hill Formation. Thickness is approximately 100 feet.	2-1-1	DMUUnit1	Tv	Tv	168,0,0	---	OF0329	Limestone	High	DMU11
