Abstract
The Kuhn-Magnyo copper-nickel deposit is located in the southeast of the Aldan-Stanovoy shield. Based on the results of geological exploration, the object is assessed as promising. The ore field, within which the deposit is located, is confined to a complex junction of several regional tectonic structures. The area has an intensely dissected relief, increased seismicity. Therefore, an assessment of the possibility of dangerous geodynamic phenomena during its operation is required. This work describes its preliminary assessment based on the results of morphometry on digital elevation models (DEM). Several morphostructural elements have been identified that directly determine the geodynamics in the area of the earth’s crust containing the deposit. The result of the study revealed a potential hazard.
Highlights
The study area is located practically at the junction of three tectonic structural units: the Ilyun structural-facies zone of the Aldan region, the ledge of the early Archean base of the Stanovoy fold system and the Udsko-May structural-facies zone of the Stanovoy system
To identify global and regional structures, digital elevation models (DEM) are used based on SRTM30, GTOPO30, containing the elevations of the relief, distributed on a regular grid with a step of 30 arc seconds
In fig. 2 and 3, one can see that over most of the area there is a breaks of the relief
Summary
The study area is located practically at the junction of three tectonic structural units: the Ilyun structural-facies zone of the Aldan region, the ledge of the early Archean base of the Stanovoy fold system and the Udsko-May structural-facies zone of the Stanovoy system. The area of the Kurumkansky ore field is confined to the junction of the Janinsky and Tuxanian blocks of the crystalline basement of the Aldan-Stanovoy shield. The Kun-Manyo field is located within several isolated, linearly elongated in the north-western direction areals of mafic-ultramafic intrusions. Ore bodies are composed of disseminated sulfide mineralization [1, 2]. The morphological features of ore bodies force at least part of the reserves to be mined underground. A preliminary assessment was made based on the morphostructural features of the areas
