Horizontal magnetic components

Submitted by antonio.menghini on Tue, 2009-12-22 04:16

Is there anybody who is working with the horizontal magnetic field components of TEM soundings ? According to many authors and to some simulations of mine, they should show a better power of resolution, in comparison with the vertical one (up to 30 %).

I have found very few papers on this topic.

My feeling is that this approach is not routinely applied by EM geophysicists

Yes, I see that Asten & Price is available for AUS $25 from http://www.publish.csiro.au/paper/EG985165.htm

 

If this is actually in the public domain and someone can upload it, then problem solved, otherwise there is a cost unless you have a subscription to the journal.

Really I have just required the membership application to ASEG, hence I should get access to the paper as soon as possible

Two references that might be of interest to you are: Spies, 1988, Local noise prediction filtering for central induction transient electromagnetic sounding, Geophysics, v53, p1068-1079. Asten and Price, 1985, Transient EM sounding by the in/out-loop method, Exploration Geophysics v16, p165-168

Thank you for the suggestions. Unfortunately I am not able to read the Asten's paper.

Spies' paper deals really with the use of H components only for noise filtering (in fact they are collected in the central-mode sounding, where theoretically they are null). On the contrary I am looking for studies where an inversion of the H components has been performed (of course it is possible only for the offset-mode soundings).

Anyhow, there could be some intersting papers among the references...I will check

Can you recommend one or two good papers that show use of horizontal magnetic field components for (terrestrial) TEM soundings?

 

Thanks

I know unfortunately only one (!!!) published paper that suggests the use of H components: Passalacqua (1983) Electromagnetic fields due to a thin resistive layer. Geophysics 31, 945-976: but they are just a few words on this topic. I hope somebody has got more informations
