Ferroan anorthosite from lunar breccia 64435: Implications for the origin and history of lunar ferroan anorthosites
A composite clast of ferroan-anorthosite-suite rocks from lunar breccia 64435 is shown to contain three lithologies. The results suggest that the structures of the 64435 composite clast were produced in an early deformation that consisted of extensive granulation followed by pervasive recrystallization, and that some granulitic breccias are nearly monomict. The REE concentrations in the coarse-gr

100 years of sedimentation study by the USGS
On January 15, 1889, the U.S. Geological Survey began collecting sediment data on the Rio Grande at Embudo, New Mexico. During the past 100 years the U.S. Geological Survey's Water Resources Division (WRD) has collected daily sediment data at more than 1,200 sites. Projects have addressed the problems associated with reservoir construction, agricultural irrigation projects, energy production, and

Artificial recharge to the Floridan aquifer system, Orlando Area, Central Florida
Approximately 400 drainage wells exist in Orange County, central Florida. The rate of recharge through drainage wells is limited by the rate of surface flow to the wells; the hydraulic properties of weirs, overflow pipes, and well casings; or the water level above the top of the casing. The rate commonly is not limited by the hydraulic properties of the very transmissive aquifer system.
