What would be the location of a pole if the azimuth/ dip is 260/ 70?

it depends wether you are working on upper or lower emisphere projections.

In upper hemisphere, locating it on a watch's dial, it would be a point almost at 9 hours, at a little distance from the dial's edge.

In lower hemisphere, it would be specularly symmetric

Thanks for the reply. How about if you wanted to plot on a stereonet?

It's difficult to describe a point on a stereo-net. The pole would be in the NW quadrant, pretty close to the center of the stereo-net, just north of the E-W meridian.

Hmm! But I think the borehole/ pole should be located in the NE quadrant. The dip should fall 70 degree on the right side of the stereonet from 90o, and for a pole you should count another 90 degree. After plotting the pole, turn the stereonet back to the original N.

Not sure what you mean by borehole?

But you are correct, I meant to say NE quadrant, and the pole would be about 20 degrees inside the edge of the stereonet.

Appreciate your reply. Borehole represented as pole.
Thank you.

Goephysics?

Are you speaking of the anatomical physique of the Goeduck?
