Structure - Answer-the three dimensional geometric arrangement of the rock units
Geologic history - Answer-The sequence of geologic events that produced the observed
stratigraphy and structure
To be a professional geologist, you need two objectives - Answer-Basic Techniques of
field geology and an understanding of the philosophical problems they entail
There is a necessity for - Answer-Professional attitude and intellectual honesty

WHAT ABOUT MY FIELD NOTEBOOK?!?!? - Answer-Should always contain the
geologist's: name, address, notice stating it contains valuable field notes and asking the
finder to return it.
*Entries should be made in pencil*
YOUR FIELD NOTEBOOK IS COMPANY PROPERTY, NOT YOURS
, Purpose of field Notebook - Answer-Record facts and observations (data)
Text, measurements, diagrams, cross sections
Record interpretations, ideas and working hypotheses
Diagrams and sketches -- always indicate perspective and scale
Planning and record of field expenses and other logistic issues
Overturned bedding symbol - Answer-
FIRST DAY OF A NEW PROJECT -Entries in a Field Notebook - Answer-Date
Title of Project
Objective(s) of project
Geographic location of project
Magnetic Declination used
Base map name and type of aerial photograph ID and approx scale
Field partner (if any)
EACH DAY Entry in a Field Notebook - Answer-Date
Weather Conditions
Field Partner (if any)
Data, observations, ideas, etc
Notes about Entries - Answer-Entries should contain all relevant information NOT on the
map, the map should be the primary vehicle for information. Never rely on memory.
Write notes in a way that, if you should die, another geologist could finish your report by
means of them.
It should be possible to tell the date and place of every entry. short phrases about
observations. Descriptions from general to specifics
Always have the final report in mind. Do not be afraid to express confusion
Map Scales - Answer-Fractional: specific to the page you are on
Graphical: this will change as you go up an down
Verbal: the least reliable
Magnetic declination - Answer-the angle between geographic north and the north to
which a compass needle points
Contour mapping rules - Answer--contour lines do not cross other contour lines
-where one closed contour line surrounds another, the inner contour line represents the
higher elevation
-Index contour - every 5th contour line is darker and has the elevation marked
-highest possible elevation will have an "x" or mark
-depressions are shown by small marks (*hachures*) pointing inwards
