l <br /> tL <br /> The site is located within San Soa <br /> gain County, Lodi, California. <br /> Lodi is located near the center of the Great Central Valley of <br /> California. This valley was formed by the filling of a large <br /> k <br /> structural trough or downwarp in the bedrock formations. The <br /> trough is situated between the Sierra Nevada Mountains on the <br /> east and the Coast Range Mountains en the west, The sediments { <br /> � I <br /> which fill the trough originated as erosional debris from the ! <br /> adjacent mountains and foothills. The bedrock.complex is <br /> {++ composed of. metamorphosed marine sediments similar to those :'ound <br /> in the foothills of the western Sierra Nevada and the eastern <br /> a i <br /> Coast.Range. Mountains. The overlying sediments exhibit a fairly <br /> a <br /> complete atratigraphic section of Cretaceous, Tertiary, and <br /> Quaternary deposits which have a maximum thickness of <br /> ,.. . <br /> 'approximately x,000 feet beneath the Lodi area. <br /> U <br /> ter } <br /> Prior to Tertiary time, sediments were apparently deposited in a <br /> 4 marine environment. Charges in sea level and subsequent uplifts <br /> resulted in later deposition of sediments in a: continental <br /> environment. The recent sediments have likely been deposited by <br /> a flooding and meandering of the Mokelumne River. The Mokelumne <br /> River- is located approximately 1.3 =ilea north of the project <br /> SAF property. It is likely that sediments of this area have also <br /> been influenced by the delta, since the present-day Stockton <br /> i <br /> �#� delta area is approximately 6 miles west of the project property. <br /> �p <br /> FJVO hydrogealogfcal soil zones have been identified within the--------- — - -- <br /> near surface sediments below the site.
