The data were extracted from a compilation for the AlbuquerqueBbasin area (U.S. Geological Survey Open-File report 00-0490 by Gillespie and others), which builds on data collected by previous workers since the 1970s. Data for the Santo Domingo Basin area originate primarily from the statewide compilation of Heywood (1992) and secondarily from a database of the Rio Grande rift maintained at the University of Texas at El Paso. Purpose: Gravity studies place constraints on basin geometry, the nature and orientation of basement structures, and regional variations in the thickness of basin fill. These constraints aid in understanding the subsurface geology that influences groundwater flow and storage in the Santo Domingo Basin and adjoining parts of the Albuquerque and Espaņola Basins. Supplemental_Information: Gravity methods rely on measurements of the Earth's gravitational field at the surface to determine changes in bulk density of the crust, whereas aeromagnetic methods measure variations in the strength of the Earth's magnetic field from the air to determine variations in magnetization. From these measurements, geophysicists deduce the spatial distribution of the physical properties in the Earth and interpret these distributions in terms of lithologic properties and subsurface structure.

This previous report describes the data collection and processing procedures for the gravity data for the Middle Rio Grande and southern Espaņola Basins. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The data in the original grids are described fully in U.S. Geological Survey Open-File Report 00-0490 and U.S. Geological Survey Water-Resources Investigations Report 91-4065. Isostatic residual gravity was constructed by removing a regional field from standard Bouguer gravity data, where the regional field is based on an Airy-Heiskanen isostatic model. The isostatic regional field parameters are fully explained in USGS Water-Resources Investigations Report 91-4065. Bouguer gravity reduction used a density of 2,670 kg/ cubic meter. Logical_Consistency_Report: The parameters used to display the gravity data (color scale) were chosen to best enhance gradients considered to represent major structures related to the Santo Domingo basin, as discussed in the text that accompanies plate 3 (chapter D in U.S. Geological Survey Professional Paper 1720). Completeness_Report: Gravity data shown in the image are limited to those collected within the public sector and available at University of Texas El Paso prior to 1999. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal position is derived from the original gridded data and mapped with respect to latitude/longitude tick marks using NAD27 projection. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The data represent variable vertical accuracy, dependent upon the source of individual data points. These are best described in the two reports describing these data: USGS Open-File Report 00-0490 and USGS Water-Resources Investigations Report 91-4065.
