A column-flow cesium migration experiment has been conducted in support of the safety assessment program for the Waste Isolation Pilot Plant (WIPP) in Southeastern New Mexico. The column was a monolithic cylinder of Magenta dolomite obtained from a core sample drilled near the proposed WIPP site. The fluid was a Magenta equilibrated de-ionized water solution that had been doped with 0.001 ppM of /sup 137/Cs. The experiment ran continuously for an 18 month period at flow rates comparable to those measured for natural groundwater at the site. After flowing for 18 months, the apparatus was disassembled and the dolomite column examined for cesium distribution. Cross sectional radiographs of the sample showed that most of the cesium had penetrated only 0.4 cm into the solid Magenta column with a well defined wave front. On the other hand, trace quantities (2 x 10/sup -7/ ppM) of /sup 137/Cs were detected in effluent samples collected during the experiment. The distribution coefficient (120 ml/gm) calculated (assuming porous flow) from the average depth of cesium penetration (0.3 cm) is considerably less than the value obtained from a batch equilibration measurement made on the same system (650 ml/gm), indicating that cesium will migrate through Magenta rock …

This following report discusses the studies and findings of the East Chaco Canyon drilling project of northwestern New Mexico. These studies took place between July and November of 1978.

Introduction: This report is a brief review of the uranium and/or vanadium mining in the eastern Carrizo Mountains, San Juan County, New Mexico and Apache County, Arizona. It was prepared at the request of the Navajo Tribe, the New Mexico Energy and Minerals Department, and the Arizona Bureau of Geology and Mineral Technology. As this report deals only with historical production data, the reader is referred to reports by Blagbrough and Brown (1955), Masters and others (1955), and Stokes (1951, 1954) for descriptions of the geology and ore deposits. Figure 1 shows the locations of the mines and the production is summarized in Table 1 and Figure 2. A separate report (Chenoweth and Learned, 1980) covers the production history of the northern and western Carrizo Mountains.

This report is an issue of the original draft copy of the "Interim Staff Report on Uranium Exploration on the Colorado Plateau", dated June 1951. The original draft copy was only recently located and is being published at this time because of the interest in the contained historical content.

From abstract: As part of the Department of Energy (DOE) National Uranium Resource Evaluation Program, a rotary-wing high sensitivity radiometric and magnetic survey was flown covering portions of the State of New Mexico, Arizona and Texas. The survey encompassed six 1:250,000 scale quadrangles, Holbrook, El Paso, Las Cruces, Carlsbad, Fort Sumner and Roswell.

A report discussing the Hydrogeochemical and Stream Sediment Reconnaissance conducted for uranium un the Socorro NTMS Quadrangle

A report describing the results of a detailed hydrogeochemical survey directed by the Los Alamos Scientific Laboratory of well waters in parts of the Saint Johns and Socorro Quadrangles.

"Objectives of the Halo Identification Project were to (1) characterize specific deposits, (2) Develop or improve genetic models, and (3) develop and evaluate cost-effective exploration methods for deposits in specific geologic environments."

This report discusses uranium findings from a reconnaissance of the Gallup NTMS quadrangle through water, sediment, and water samples collected from streams, springs, and wells.

From introduction: This report describes the objectives, scope, design, drilling and hydrologic history, and the test results collected during permeability testing of sub-horizontal boreholes drilled in the waste-handling shaft (WHS) at the Waste Pilot Plant (WIPP) site located in southeastern New Mexico.

From abstract: The La Jencia fault is a recently reactivated late Cenozoic basin margin structure of major proportions that forms the western margin of the Rio Grande rift, which borders the eastern sides of the northern Magdalena Mountains and the southern Bear Mountains in central New Mexico. Stratigraphic throw on the fault has not been determined, but Precambrian rocks of the Magdalena Mountains are uplifted a minimum of 800 m (meters) above the adjacent basin floor, below which lie a thick section of upper Cenozoic basin-fill deposits. Most of the implied displacement is probably Neogene in age.
