The Mongol-Okhotsk suture and the Adaatsag ophiolite belt are associated with the closure of the Mongol-Okhotsk paleo-ocean and are located within the Central Asian Orogenic Belt (CAOB) and Mongolia. The suture zone is flanked by volcanic-plutonic belts that host significant meta ...

Regional magnetotellurics across Mongolia

Constraining lithospheric properties and architecture

Mongolia is a region of major scientific relevancy because it is a prime example of continental intraplate surface deformation, which is poorly studied and not well understood. There are open questions regarding the tectonic evolution of the region, including the closure of the M ...
Within the Ulaanbaatar region, Mongolia, 120 earthquake events were recorded with a magnitude between 3.4 and 5.6 and 978 earthquake events had a magnitude between 2.5 and 3.4, for the period from 1994 to 2016. Several of these have been strongly felt by residents of Ulaanbaatar. ...
We are investigating the lithospheric properties and lithospheric architecture beneath Mongolia with three-dimensional models of the electrical resistivity generated from magnetotelluric measurements. In addition, thermo-mechanical numerical modelling, with geophysically-guided c ...
Deformation in the continental interior, far from tectonic plate boundaries, is not fully understood. Due to its location, Mongolia is a prime natural laboratory for studying effects such as intracontinental deformation and intraplate volcanism. A previous regional magnetotelluri ...

Magnetotelluric Data Across Mongolia

Implications for Intracontinental Deformation and Intraplate Volcanism — Report on New Measurements

Intracontinental deformation and intraplate volcanism, which occur far from tectonic plate boundaries, are not fully understood. Their origin and evolution are linked by crust-mantle interactions and mantle convection dynamics. Mongolia is an ideal natural laboratory for studying ...

Investigating the whole-lithosphere structure of a mineral system

Pathways and source of ore-forming fluids imaged with magnetotelluric modeling

Whole-lithosphere structure has direct implications for both the genesis of minerals and the locations of mineral emplacement; thus knowledge of the deep structural framework of the lithosphere can advance understanding of the development and evolution of mineral systems (e.g., H ...

An Asthenospheric Upwelling Beneath Central Mongolia

Implications for Intraplate Surface Uplift and Volcanism

Intraplate processes, such as continental surface uplift and intraplate volcanism, are enigmatic and the underlying mechanisms responsible are not fully understood. Central Mongolia is an ideal natural laboratory for studying such processes because of its loca ...
Central Mongolia is a prominent region of intra-plate volcanism and deformation. To study these processes, many of which are poorly understood, magnetotelluric data was collected in the Hangai and Gobi-Altai region in central Mongolia. The geologic history of this region exhibits ...
The Bayankhongor Metal Belt passes through the Valley of the Lakes, south-central Mongolia, between the Hangai Dome and the Gobi-Altai Mountains. It is an important region because it is associated with significant mineral occurences, including important sources of gold and copper ...

Images of intraplate volcanism

The upper crustal structure below Tariat volcanic zone, Mongolia, imaged with magnetotellurics

West-central Mongolia is characterized by the Hangai Dome, and intra-continental plateau, and by dispersed, low-volume, intraplate, basaltic volcanism. The results of a recent broadband magnetotelluric study across the young volcanic zones of Tariat and Chuluut are presented. The ...
The Valley of the Lakes, south central Mongolia is located between the uplifted Hangai Dome and the Gobi Altai Mountains , within the Central Asian Orogenic Belt . It includes many interesting features, including t he South Hangai f ault system that represents an ancient suture z ...
