Dealing with magnetic data at low latitudes

[ziongeophysics]

Hi Geophysicists,

I recently published a couple of articles on my blog @ ziongeophysics.com dealing with processing and interpretation of magnetic data acquired at low latitudes and containing effects of remanence, etc.

I finished up deciding that Geosoft's Magnetization Vector Inversion, when used in conjunction with Iterative Re-weighting Inversion focusing and selecting an appropriate scalar quantity to use for mapping the results, provided the best solution (at least the best that is readily available to most practitioners; I'm always happy to look at recent developments from academia, service providers, etc). Rather than focusing on studies using model data, I chose to use a warts-and-all ground magnetic dataset, to see how different methods perform on real data.

Take a look and let me know what you think:

While you're there, take a look at some of the other pieces I published on my blog, as well as the rest of my website. I'm always looking for work, or even a full-time job in the right company. But I also like to hear about experiences other people had dealing with the same problems in geophysics and exploration generally.

I also summarized the material from these two blog posts in an article on LinkedIn intended for a more general audience (though I never seem to resist the temptation to go in-depth...):
