Who produced the data set?

1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
   • Edward J. LaRock
   • Samuel L. Moore

2. Who also contributed to the data set?

3. To whom should users address questions about the data?

Why was the data set created?

To provide to the public a digital geologic map of the Roswell resource area, New Mexico.

How was the data set created?

1. From what previous works were the data drawn?

   Bartsch-Winkler (1992) (source 1 of 1)

   Bartsch-Winkler, Susan, ed., 1992, Mineral and energy resources of the BLM Roswell Resource Area, east-central New Mexico: U.S. Geological Survey Open-File Report 92-0261.

   Type_of_Source_Media: paper

   Source_Contribution: Digital geologic map was digitized information in this report.

2. How were the data generated, processed, and modified?

   Date: unknown (process 1 of 1)

   Geologic data was transferred onto a 1:500,000-scale stable greenline base with a Lambert Conformal Conic projection and digitized from the greenline base using GSMAP 6 (Selner and Taylor, 1989). The digital line data was then transferred to ARC/INFO via GSMARC 1.0 (Green and Selner, 1988). Geologic polygons were built using ARC 5.0 to produce the final color geologic map for publication. Geologic data was modified from the New Mexico Highway Geologic Map (New Mexico Geological Society,1982) according to the following:
   Quaternary gravels in Carrizozo Valley were remapped as Quaternary and Tertiary intermountain gravels. Tertiary intrusive dikes contained in the Tertiary volcanic flows of the Sierra Blanca area on the southwest part of the Roswell area were omitted for simplicity. Near the west edge of the Tertiary volcanic flows, a Tertiary intrusive stock and an outcrop of associated Cretaceous sedimentary rocks were deleted, because they were not located during fieldwork by Moore. Subdivided Cretaceous units on the New Mexico Highway Map have been modified to include two units -- KTru, that includes the Pajarito Shale, Mesa Rica Sandstone, and Tucumcari Shale; and Kmmd, that includes the Redondo Sandstone, and the Mesaverde, Mancos, and Dakota Formations. In the northeastern corner of the Roswell geologic map, Ku represents only the Dakota Sandstone, and in the Ruidoso-Capitan area, Ku represents the undifferentiated Dakota, Mancos, and Mesaverde Formations. The San Andres Formation and the Glorieta Sandstone (Psg) crops out in the northwestern corner of the Roswell Resource Area. Abo, Hueco, Yeso, and Bursum Formations are undivided (Pu). The Bonito Fault in Lincoln County was not extended into the Capitan intrusive as indicated on the New Mexico Highway Map, and the southwestern extent of the Sixmile Buckle was omitted owing to lack of surface evidence. Most minor faults were deleted for simplicity, but a small fault cutting the Santa Rosa Sandstone was added along U.S. Highway 84 west of Santa Rosa.

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   Complete

5. How consistent are the relationships among the observations, including topology?

   This geologic map was prepared for a report on the mineral and energy resource potential of the Roswell Resource Area that is managed by the Bureau of Land Management (Bartsch-Winkler, 1992). Geologic map information was compiled, modified, and digitized at 1:500,000 scale from the New Mexico Highway Map (1982).
