Contour

I am doing Tilt derivative map.How to get +45 degree and -45 degree contour and depth from it?

Hi @PankajKumarDas, There was a webinar last year about modelling a geothermal prospect. In this webinar Gerry Connard uses Tilt Derivative to calculate magnetic depth to basement solutions as part of the modelling process. He provides a Geosoft script that will determine the distance from the zero contour to +/-45 degree contours for you.

Information on the script file and a link to the webinar can be found in this forum post: https://my.geosoft.com/forum#/discussion/comment/3386. The part about using the tilt derivative start around 9:43 but it's a great webinar worth watching in it's entirety if you missed it!

Once u get ur tilt map Go to contour and insert the values 0 ; 0.785; and -0.785 in the respective contour lines

There's also an Exploring with Data blog post about it here: https://blogs.geosoft.com/exploringwithdata/2018/01/tilt-derivative-script.html
