ANDESITIC-DACITIC VOLCANISM OF THE LENA-VILYUY WATERSHED: THE VOLCANIC STRUCTURES AND METALLOGENIC SPECIALIZATION (EAST SIBERIAN PLATFORM)

The article discusses the structural features of Tyugeninskiy field of volcanic rocks on the Lena-Vilyui watershed, which is located close to major highway and available for scientific research. There are two types of volcanic units: andesitic type is presented by pyroclastic volcanic cone and ring bars around the cone, dacitic type ? by volcanic cone and several lava flows. The placement of igneous rocks is controlled by snaps with left shift kinematics.
