Contour

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!

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