Suggestions, corrections, or comments? The “line” either is the horizontal projection of an inclined linear object, or a horizontal line on an inclined plane. Thus, in Europe and other places, the format may be dip amount, dip direction, which is a vector e. Once all three are lined up and the compass is level, the reading for that azimuth can be made. Some discussions are given in the context of the lower hemisphere stereographic projection brunton compass manual the brunton compass manual objects for the bfunton of clarity and practical value.

The magnetic compass has been used kanual a direction-finding device. On a typical topographic map, the magnetic declination is indicated as shown below: Brunton compass manual quadrant scale uses manal alphanumeric notation e. There are numerous other compasses used by geologists: Bearing is a scalar feature, i. By pressing ‘print’ button you will print only current page.

If you are East of the zero declination line, your compass will brunton compass manual West of true North, This is called westerly declination. Unlike analogue compasses, janual digital compass relies brunton compass manual an accelerometer and a teslameter, and may provide much information as to the reliability of a measurement e.

See why the E and W on compass faces are reversed? To take a bearing hold the compass level in front of you.

Page of 4 Go. If next brunton compass manual the feature, the strike is measured by leveling with the bull’s eye level the compass along the plane being measured.

When the true dip orientation and magnitude is registered, measure the strike of the plane perpendicular to this line. Since they are measured only using brunton compass manual rotating leveldip measurements brunton compass manual unaffected by magnetic fields. Detailed measurement of geological objects, such as fold hingeline, axial trace, and axial plane, and geological mapping becomes essentially impractical without the use of the compass i.

brunton compass manual It wasn’t until centuries later when mariners in China and, by the 12th century, mariners in Europe noticed that a piece of lodestone, when floated on a stick in a bowl of water, aligned itself to point in the direction of the north star. This is called azimuthal notation.

To determine the magnetic declination in a study area we can use: To determine the orientation of the plane that contains the two lines, plot the lines as two points on the stereonet, and align them on brunton compass manual same great circle.

Measuring pitch is only possible if the linear feature lies on a physical plane. For brunton compass manual, if the user is near an outcrop that contains magnetite or some other iron -bearing material, compass readings can be affected anywhere compzss several inches from the outcrop to tens of yards away depending on the strength of the magnetic field.

How to use a Brunton Compass

Don’t have brunton compass manual account? Since strike is the bearing of a horizontal line, we can read the bearing of either of its ends; thus, o brunton compass manual o are the same strike. Pitch is an alternative to trend and plunge, although, sometimes, it is the only practical way of measuring a line correctly, especially if the line is steeply plunging. If the linear feature is above our head e.

In either case, level the bull’s eye, round level while aligning. Stretch the brunton compass manual arm and bend the sighting tip. Determining the magnetic declination If the compass needle points east or west of the true north, the offset is called east or west declination, respectively.

Contact Steven Schimmrich at schimmri kutztown. Magnetic declination is constant along the so-called isogonic lines.

The different features unique to a Brunton compass will be discussed in other tutorials when we learn how to measure the orientations of geologic structures and how to create a geologic map.

With the brunton compass manual of portable electronic devices a new generation of compasses has emerged, some again of specific interest to geologists.
