No less indicative are the apparent-resistivity curves obtained on the Kamchatka
peninsula (Fig. 12.14). At many sites, the descending branches of the longitudinal
-curves lie between the h- lines 40 and 60 km detecting the elevation of the par-
tially melted asthenosphere in the region of contemporary volcanism. At the same
time, the transverse
-curves exhibit the vertical scattering that ranges up to two
decades and is hard of interpretation.
The last example is drawn from the magnetotelluric soundings carried out in the
mountains of the Kirghiz Tien Shan (Trapeznikov et al., 1997). The longitudinal and
transverse apparent-resistivity curves,
, are presented in Fig. 12.15. The
