Geologic Map and Report for the Proposed State Route 95 Realignment Corridor, Mohave County, Arizona, v. 1
Dataset Identification:
Resource Abstract:
These geologic map sheets and report encompass the proposed State Route 95 RelocationCorridor in Mohave Valley, western Arizona,
between the Black Mountains on the east and theColorado River on the west (Figure 1). The maps were developed through compilation
ofexisting geologic mapping and extensive new geologic mapping. The map area includes aportion of the historical floodplain
of the Colorado River, a broad swath of the piedmont east ofthe river, parts of western flank of the Black Mountains, the
channels and terraces of SacramentoWash, and the northernmost piedmont of the Mohave Mountains (the Powell Mountain area).The
corridor is predominantly covered with late Miocene and younger alluvium deposited bylocal tributary washes and the Colorado
River. Deposits range in age from modern to at least 8Ma (millions of years ago), and deposit characteristics and composition
vary substantiallydepending on whether they were emplaced by the modern Colorado River, older versions of theriver, or tributary
washes derived from the Black Mountains or the northern end of the MohaveMountains. The northern, northeastern, and southernmost
parts of the map include a variety ofbedrock types ranging in age from early Proterozoic to middle Miocene. This map and reportdescribe
the physical characteristics of geologic units of different ages and sources, the mappedextent of various geologic units,
and potential geologic resource and geologic hazardimplications of this mapping. These maps include modified versions of portions
of severalpublished maps that have been completed in this area since 1997 (Howard et al., 1997; Howardet al., 1999; Faulds
et al., 2001; Murphy et al., 2004; Pearthree and House, 2005; Pearthree,2007; Spencer et al., 2007; Malmon, in review). Extensive
new surficial geologic mapping andbedrock mapping was done where needed.
