2002, Professional Paper 1419
Poorly lithified to unconsolidated carbonate and clastic sedimentary rocks of Tertiary (Oligocene to Pliocene) and Quaternary (Pleistocene to Holocene) age compose the South Coast aquifer and the North Coast limestone aquifer system of Puerto Rico; poorly lithified to unlithified carbonate rocks of late Tertiary (early Miocene to Pliocene) age make...
Age and tectonic significance of volcanic rocks in the northern Los Angeles Basin, California
Thane H. McCulloh, Robert J. Fleck, Rodger E. Denison, Larry A. Beyer, Richard G. Stanley
2002, Professional Paper 1669
Volcanic rocks, mostly basalts and some andesites, are interbedded with middle Miocene strata and are overlain by younger rocks throughout the greater part of the Los Angeles Basin, California. Roughly correlative flows, previously dated radiometrically (or paleontologically) at about 16.4 to 10.7 Ma, crop out in five separate regions around...

Charles E. Heywood, Devin L. Galloway, Sylvia V. Stork
2002, Water-Resources Investigations Report 2002-4235
Six synthetic aperture radar (SAR) images were processed to form five unwrapped interferometric (InSAR) images of the greater metropolitan area in the Albuquerque Basin. Most interference patterns in the images were caused by range displacements resulting from changes in land-surface elevation. Loci of land- surface elevation changes correlate with changes in...

Charles Schalk, Thomas Schumann
2002, Water-Resources Investigations Report 2002-4167
Withdrawals of ground water in the central Mill Creek Valley near Evendale, Ohio, caused water-level declines of more than 100 feet by the 1950s. Since the 1950s, management practices have changed to reduce the withdrawals of ground water, and recovery of water levels in long-term monitoring wells in the valley...
