|---|---|
| contact_certain | Boundary between two mapped units that retains the original depositional or intrusive relationship. The contact has been observed or is closely constrained, so it is well located as described in Positional_Accuracy. |
| high_angle_flt_certain | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault has been observed or is closely constrained, so it is well located as described in Positional_Accuracy. |
| high_angle_flt_concealed | Structural boundary between mapped units or structural discontinuity withina mapped unit that has experienced relative offset between the rok bodies on either side of the fault. The fault is obscured by overlying mapped units, so it is not well-located as described in Positional_Accuracy, but the location isconstrained to be within 3 mm at mapscale or within about 95 meters on the ground |
| map_boundary | Edge of the mapped area. Used primarily to bound polygons at the edge of the map database. The location of the boundary is well located as described in positional_accuracy. |
| Value | Definition |
|---|---|
| fault_ball_fill | Arcmarker attached to an arc describing the nature of displacement along a fault. Side of arc with bar and ball is the side with downthrown displacement. |
| xx | No arcmarker is to be attached to an arc containing the xx value in the PTTYPE field. |
| Value | Definition |
|---|---|
| anticline_certain | The surface trace of the axis of an anticline. The axis cannot been observed, but the location is constrained to be within about 3 mm at map scale or within about 72 meters on the ground. |
| monocline_certain | The surface trace of the axis of a monocline. The axis cannot been observed, but the location is constrained to be within about 3 mm at map scale or within about 72 meters on the ground. |
| monocline_concealed | The surface trace of the axis of a monocline. The axis cannot been observed, but the location is constrained to be within about 3 mm at map scale or within about 72 meters on the ground. The axis is concealed by younger units unaffected by earlier folding. |
| syncline_certain | The surface trace of the axis of a syncline. The axis cannot been observed, but the location is constrained to be within about 3 mm at map scale or within about 72 meters on the ground. |
| syncline_concealed | The surface trace of the axis of a syncline. The axis cannot been observed, but the location is constrained to be within about 3 mm at map scale or within about 72 meters on the ground. The axis is concealed by younger units unaffected by earlier folding. |

|---|---|
| anticline | Point element placed on line indicating the anticlinal nature of the particular fold axis. Defined only in conjunction with an LTYPE of anticline_certain |
| monocline | Point element placed on line indicating the monoclinal nature of the particular fold axis. Defined only in conjunction with an LTYPE of monocline_concealed or monocline_certain |
| syncline | Point element placed on line indicating the synclinal nature of the particular fold axis. Defined only in conjunction wiht an LTYPE of syncline_certain or syncline_concealed |
| xx | No point element is to be placed on an arc with PTTYPE defined as xx |

Thank you to Scott Graham for his digital review of the database and to Jan Zigler for editing the layout. Thanks also to Carolyn Donlin and Rich Koch for making this data available on the WWW.
This geologic map is part of a cooperative project between the U.S. Geological Survey and the Kaibab National Forest Service to provide geologic information for the Paradine Plains Cactus (Pediocactus pardinei B,W. Benson) Conservation Assessment and Strategy conducted by the Kaibab National Forest, Williams, Arizona. The map area includes part of House Rock Valley and part of the Kaibab Plateau, sub- physiographic provinces of the Colorado Plateau. This part of the Colorado Plateau was not previously mapped in adequate geologic detail. This map completes one of several remaining areas where uniform quality geologic mapping was needed. The geologic information in this report may be useful to land management, range management, and flood control programs for all federal and state agencies, and private affairs.
