Abstract
Physical properties of rocks from western Priokhotye were studied and petrophysical maps revealing large-scale heterogeneities of tectonic elements of the territory were constructed. Petrophysical heterogeneities and anomalies of respective geophysical fields were compared. A relationship between magnetic anomalies and near-surface rock assemblages is established only for the Mesozoic volcano-plutonic structures of the Okhotsk-Chukotka volcanic belt and partially for the Yudoma-Maya tectono-stratigraphic area. In the ancient blocks of the Aldan-Stanovoy shield and the Uchur-Maya plate, magnetic anomalies are mainly associated with the intensification of tectonic-magmatic processes and to a lesser extent with magnetic properties of specific rocks. Inverse relationships are established between gravity anomalies and rock dense anomalies within the regions of gravity low (Tyrkansky and Yuzhno-Verkhoyansky gravity fields) and the Vilyui syneclise, where domains of gravity high correspond to domains with low density.
