From introduction: This report describes work done in the Aztec, New Mexico, National Topographic Map Series (NTMS) quadrangle (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From preface: The report which follows is the second phase of a DOE contract designed to address various aspects of the genesis of the uranium deposits of the Grants mineral.belt. Many of the problems outlined in Phase 1 of this study (Brookins, 1976a) have been answered, others have been raised.

Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.

From introduction: This report describes work done in the Tularosa, New Mexico, National Topographic Map Series (NTMS) quadrangle (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

"Eight high-explosive charges weighing 8 to 1000 pounds were detonated in playa. Each event included 24 to 40 locations of tracer material in the expected crater region. The objective was to obtain data relating the origin of crater ejecta to its depositional location. Resulting data are presented for craters, ejecta areal densities, crater and ejecta mass quantities, tracer dispersion, and an empirical prediction model."

From introduction: To improve understanding of uranium mineralization of the Todilto Limestone of Late Jurassic age in the Grants district, New Mexico, the mines active in 1957 were reviewed to determine the major types of deposits. A representative example of each type was selected and mapped in great detail to establish a prototype. It was hoped that the analysis of prototypes might shed considerable light on the mineralization process and aid evaluation of other deposits by offering a standard of comparison.

This is a report on aerial gamma ray and magnetic survey, Raton Basin Project, in the Albuquerque Quadrangle, New Mexico.

From introduction: This final report .is organized in two logical sections: (a) Volume I, containing the survey description, specifications, data processing methods, interpretation methods, regional geologic review and regional survey results and (b) one volume, Volume II, for each of the three quadrangles covered by the Raton Basin Project Area. Each Volume II contains a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer-controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.
