Overview of attributes

The ARC/INFO version of the Digital Geologic Map of the Cougar Buttes
7.5'quadrangle consists of five coverages:
1)	coug_geo - geology
Geologic units are delineated by geologic line entities and
described by polygons which are attributed with the following set
of attribute items in coug_geo.pat.  For display purposes, the
geology coverage contains three annotation subclasses: anno.geo
contains unit labels, anno.fault contains formal fault names, and
anno.twn_rnge contains township and range data.

PLABL	coded geologic map unit label used to generate plot labels
with relevant stratigraphic symbols. The geologic units with
LABL MzPrgg (Mesozoic or Proterozoic) and Prgn (Proterozoic)
appear as }<gg, <gn respectively in the item PLABL.
The replacement characters call their corresponding symbols
from the Stratagem Font Group.  Geologic map unit labels will
plot on derivative  map plots with appropriate stratigraphic
symbols if PLABL is used as the source of unit labels.
The Stratagem Font Group is accessed through geofont.txt,
and is included in the data package.
TAG	enables identification of polygons, within a unit, of which
the geology is sufficiently distinct from that of the overall
unit.  The default designation is the unit label with the
suffix A.  Polygons representing unique properties other
than the default can be identified with suffixes B, C...etc.
All polygons in the Cougar Buttes quadrangle are designated
by the suffix A.
SHDPS	polygon color from shadeset scamp2.shd (included in the
data package)
NAME	geologic name of each unit
SHDFIL	polygon fill pattern from shadeset geology2.shd (included
in the data package)
Geologic lines, which include features such as faults, contacts,
and marker horizons  are attributed with the following set of feature
attribute items contained in coug_geo.aat.
(A complete description of each line type is available in the data
table, lines.rel.)

L-SYMB	calls up the appropriate line symbol from the lineset
geoscamp2.lin (included in the data package)
L-NAME	formal name, where applicable, of geologic linear feature
The Helendale Fault is the only formally named fault
in the Cougar Buttes quadrangle.
2)	coug_str - structural lines
Geologic stuctural features in the Cougar Buttes quadrangle
include upright anticlines and upright synclines. The attribute
values, L-TAG and L-SYMB, link the line tag to the data table,
lines.rel and call up the appropriate line symbol from the
lineset geoscamp2.lin respectively.

P-DIP		the dip of planar features
P-STRIKE	the azimuth strike of planar features
P-SYMB		calls the point-type from the markerset
geoscamp2.mrk (included in the data package)
P-TAG		point tag which consists of a character(s) and
numerical value, e.g. FN42, allows the user to relate
the point entity to its corresponding definition in
the data table, points.rel
Point types (quantitative orientation data) in coug_pts.pat and
their corresponding, abbreviated descriptions from points.rel:
>
>B2	Bedding attitude, sedimentary, inclined
>FN42	Foliation attitude, metamorphic, inclined
>L26	Lineation, metamorphic, minor fold axes, sinistral
>	rotation
>
P-PLUNGE	lineation plunge value
P-DIPDIR	azimuthal direction of dip
To date, there is no other way to indicate to the user the
cardinal direction of dip using the traditional convention
(traditional geologic notation allows a quadrant
designation following the dip value).
4)	coug_ptsorn - structural line ornamentation
The point data included in coug_ptsorn allow a visual representation
of the type of structural linear feature, e.g. anticline and syncline
symbols.  The items P-TAG and P-SYMB link the point tag to its full
description in points.rel and call up the appropriate point symbol
from geoscamp2.mrk.

entities are attributed with only  a single attribute, L-SYMB, and
all have the same value, 1.

The data dictionary tables, lines.rel and points.rel each
contain three items: L-TAG and P-TAG establish the links
between the .aat, and the .pat to the respective data
tables. The items L-DEF and P-DEF, respectively provide the
coded definition for an entity.  The items L-EXP and P-EXP
provide a parsed explanation of the code contained in the
corresponding -DEF items.
