Youanmi MT Survey 2010 (Geoscience Australia) BBMT 134 / LPMT 49

Magnetotelluric survey · Western Australia · Geoscience Australia

Geoscience Australia recorded 184 magnetotelluric soundings between 22 May and 16 August 2010 along the Youanmi deep seismic reflection traverses 10GA-YU1, 10GA-YU2 and 10GA-YU3 in the Yilgarn Craton, Western Australia, funded by the Geological Survey of Western Australia; 183 are served here and one is withheld.

About this survey

Geoscience Australia recorded 184 magnetotelluric soundings between 22 May and 16 August 2010 along the Youanmi deep seismic reflection traverses 10GA-YU1, 10GA-YU2 and 10GA-YU3 in the Yilgarn Craton, Western Australia, funded by the Geological Survey of Western Australia; 183 are served here and one is withheld. As recorded, the survey occupies 160 distinct positions: 135 broadband soundings about 5 km apart (134 served) and 49 long period soundings about 15 km apart, 24 of them beside a broadband site. Broadband sites recorded two horizontal magnetic components on induction coils, long period sites three components on a Bartington fluxgate, both on Earth Data PR 6-24 recorders with GPS timing and two orthogonal L-shaped electric dipoles of 41 to 52 m. Transfer functions were processed with BIRRP and remote referenced. Served periods run 0.0267 s to 655 s at broadband sites and 1.07 s to 13,107 s at long period sites, which alone carry the tipper. README.md carries the caveats.
