Deep electromagnetic (MT and AMT) sounding of the suture zones of the Ukrainian shield

The article discusses the results of deep magnetotelluric sounding of suture zones in the Precambrian structures of the Ukrainian shield in the context of collisional settings. All the considered suture zones (Orekhovo-Pavlograd, West Ingulets-Krivoi Rog, Golovanevsk-Yadlov-Traktemir, Nemirov-Kocherov or Brusilov) are associated with the regional anomalies of increased electric conductivity, which mark deep fault zones and characterize collisional settings. The nature of such deep anomalies might be due to the transport of the ore components together with the fluids from the crust and the mantle during the tectonomagmatic activation, which offers the possibility to predict the prospective areas of endogenic mineralization. A correlation has been established between the endogenic ore deposits located close to or within the suture zones and the low-resistivity anomalies.
