towards the chersky mountain range of eastern siberia (russia), as seen at right. from the chersky range, the north american plate boundary continues along the oceanic, divergent gakkel ridge, which becomes the mid - atlantic ridge (steblov, 2003) .
…of the lena, and the chersky range, which reaches a maximum elevation of 10, 325 feet (3, 147 metres). north of this system the low - lying, swampy kolyma lowland fronts the arctic ocean, extending for some 460 miles (740 km) to the chersky range. …
( e. g. , mount pobeda [ victory ], 10, 325 feet [ 3, 147 metres ]). the upper courses of the kolyma and indigirka rivers flow along narrow valleys between the ranges, cutting through them in majestic gorges. the southern part of the chersky range is a series of plateaus separated by depressions .
the chersky seismic belt (ne - russia) forms the modern plate boundary of the eurasian−north american continental plate. the geodynamic evolution of this continent−continent setting is highly complex and remains a matter of debate, as the extent and influence of the mid - arctic ocean spreading center on the north asian continent since the eocene remains unclear. the progression from a tensional stress regime to a modern day transpressional one in the chersky seismic belt, makes the understanding even more complicated. the alkaline volcanism that has erupted along the chersky range from eocene through to the recent can provide constraints on the geodynamic evolution of this continental boundary, however, the source and petrogenetic evolution of these volcanic rocks and their initiating mechanisms are poorly understood .
…sayan mountains, the stanovoy and chersky ranges, and the marginal ranges of the west asian highlands were deeply cut by the rivers, which created deep superimposed gorges and canyons. …
plate interactions in northeastern russia have been studied using seismological and structural field investigations; however, tectonic interpretations in the region remain widely debated and unknown. the chersky fold and thrust belt in northeastern russia is situated on the western margin of the north american plate adjacent to the indigirka - zyryanka foreland. within it lies the moma basin system, often interpreted as a continental rift environment, and the moma range, a topographically elevated antiformal structure. we apply fluvial geomorphological techniques, specifically longitudinal stream profile analyses, to rivers that dissect the internal regions of the chersky fold and thrust belt and proximal regions of the adjacent foreland. the major river draining the central chersky region, the indigirka, increases its sinuosity as it cuts through the moma range, which may be an indication of active fold growth. the rivers draining the northern slope of the moma range form a linear pattern of transient knickpoints near the myatis thrust, and this along with a trend of minor seismic events in the region suggests that the myatis is acting as a frontal thrust sheet. our study supports the idea of compression along the north american - eurasian plate boundary, and that the moma basin system may be an actively forming wedge top basin with fold and thrust growth to the north in the moma range .
the chersky range is a chain of mountains in northeastern siberia between the yana river and the indigirka river. it generally runs from northwest to southeast through the sakha republic and magadan oblast. the highest peak in the range is peak pobeda, which is 3, 003 meters tall. the range lies on the boundary between the eurasian and north american tectonic plates. - - - image - copyright - and - permission - - - about the author (s): michiel1972, using demis maps license: public domain author (s): michiel1972 (urltoken) - - - image - copyright - and - permission - - - this channel is dedicated to make wikipedia, one of the biggest knowledge databases in the world available to people with limited vision. article available under a creative commons license image source in video
a scenario of major plates (eur: eurasia, nam: north america; pac: pacific) and microplates (amu: amurian, okh: okhotsk) investigated in this work. gps observations confirmed that siberia to the east of the chersky range belongs to the north american tectonic plate. existence of the microplates was not confirmed. the pole of relative rotation of eur and nam determined from gps (blue circle) differs from the geologically determined pole (green circle), probably because of reorganization of the plate motion within the last 3 million years. the recent large hokkaido earthquake (red star) illustrates the fact that the seismic activity is associated with plate boundaries .
we studied basanites of the central chersky belt, which are thought to represent the first alkaline volcanic activity in the area, after initial opening of the arctic ocean basin. we present mineral and bulk rock geochemical data as well as sr–nd–pb–hf isotopes of the alkaline suite of rocks combined with new precise k–ar and 40 ar / 39 ar dating, and discuss an integrated tectono - magmatic model for the chersky belt. our findings show that the basanites were generated from a homogeneous asthenospheric mantle reservoir with an em - 1 isotopic flavor, under relatively ‘dry’ conditions at segregation depths around 110 km and temperatures of ~ 1500 °c. trace element and isotope systematics combined with mantle potential temperature estimates offer no confirmation of magmatism related to subduction or plume activity. mineral geochemical and petrographical observations together with bulk geochemical evidence indicate a rapid ascent of melts and high cooling rates after emplacement in the continental crust. our preferred model is that volcanism was triggered by extension and thinning of the lithosphere combined with adiabatic upwelling of the underlying mantle at 37 ma. this suggests that at that time, rift tectonics in the mid - arctic ocean most likely had also affected the north - asian continent, causing volcanic activity in the chersky belt, before the regional geodynamic regime changed from a tensional to compressional. our conclusions contribute not only to the understanding of volcanism in the chersky seismic belt (ne - russia) but also to general aspects of plate dynamics between the eurasian and north american continent .
within the bounds of the north american plate lie several remarkable geological subprovinces. the shallow dip of the kula plate subducting beneath the west coast of north america during the laramide orogeny generated the rocky mountains far inland. (marshak 2008) the basin and range province in southwestern united states represents an area of thinned and stretched continental crust. tertiary highlands underwent widespread normal faulting, creating horst mountains and graben valleys. the basin and range is believed to have formed from back - arc spreading, plume induced spreading, or from movements along the san andreas fault. (wicander 2004) the appalachians and ouchita mountains of the east coast are what remain of a series of mountain building events that began in the early paleozoic. collisions with other major plates and microplates uplifted the mountains to heights comparable to the present - day himalayas. (wicander 2004 )
from 1996 to 2002, the team of scientists measured the position of more than 50 points throughout the region. by looking for very small changes in relation to one another and to the stable interior of both plates, the team was able to determine that the boundary of the eurasian and north american plates passes through the cherskiy range in eastern siberia. in addition, they calculated the relative rates of rotation of the eurasian, north american and pacific plates and found that they differ by five to seven percent from the geologic plate model .

two columbia university researchers, in collaboration with scientists in russia and the u. s. , recently resolved a decades - old debate when they discovered that the boundary between the north american and eurasian tectonic plates passes through eastern siberia. the study carried out by mikhail kogan and christopher scholz at columbia' s lamont - doherty earth observatory, grigory steblov and dmitry frolov of the russian academy of sciences, robert king at the massachusetts institute of technology and roland bürgmann of the university of california, berkeley appeared in a recent issue of geophysical research letters. in addition to pinpointing the location of the boundary, their work used the satellite - based global position system (gps) to determine the relative motion of three of the major tectonic plates that make up the earth' s crust .
about 99 percent of earthquakes occur at the faults between plates such as the san andreas fault in california, which marks the boundary between the pacific and north american plates. geophysicists generally use concentrated belts of seismic activity to pinpoint the exact location of boundaries, but some are notoriously diffuse. the junction between eurasian and north american plates, which together comprise most of the northern hemisphere, is not only poorly defined seismically, but it passes through a sparsely populated, arctic region of eastern siberia where there is very little in the way of seismic detection equipment. as a result, the precise location of the boundary has been unverified since the theory of plate tectonics was widely accepted in the late 1960s .
by using gps data instead of the geologic record, the researchers also hoped to discern the actual movement of the plates relative to one another. geophysicists have for years relied on the so - called geologic plate model to calculate the motion of plates. the model uses geologic data such as anomalies in the record of the earth' s magnetic field over the past three million years to estimate the present rate and direction of tectonic plates .
their research was supported by grants from the national science foundation, nasa' s jet propulsion laboratory and the incorporated research institutions for seismology .

the north american tectonic plate, shown above, encompasses the majority of the surface area of north america, as well as greenland, the northern caribbean, and parts of siberia (russia), iceland, and the azores (portugal). (dutch, 2009) the large plates with which it is in contact are the eurasian, african ,
plates; as the number of neighbouring plates suggests, the north american plate is rife with tectonic activity .
the north american plate’s interactions with other plates generate various geologic features on its surface, from mountain belts to faults. a few noteworthy examples are detailed below. for a complete map of tectonic plate boundaries and their velocities of activity, as well as of seafloor age, follow this link: urltoken you can use it to follow along the plate boundaries as they’re described below. to the east, the north american plate shares the mid - atlantic ridge with the eurasian plate. this divergent margin, offset throughout by transform faults, began spreading approximately 180 ma ago, opening the north atlantic ocean (kearey, 2009). evidence of mesozoic juvenile crust formation in new england can be correlated with the event (mchone, 1984). below, a video shows the simulation of a spreading ridge like the mid - atlantic ridge with wax .
along the western border of the north american plate in a dextral transform fault lies the pacific plate (nicholson, 1994). their contact is broken by several plates and microplates :
, these plates are what remain on the earth’s surface of the farallon plate, a section of basaltic oceanic lithosphere that has almost fully subducted beneath the plates composing north, central and south america (pavlis, 2012) .
the san andreas transform boundary between the pacific and north american plate originates from the shallow, oblique subduction by the north american plate of the monterey microplate (a fragment of the farallon plate sharing a spreading ridge with the pacific plate) (nicholson, 1994). by 20 ma, the monterey - pacific ridge stopped spreading and monterey accreted to the pacific plate. as a result, the pacific plate’s motion with respect to the north american rotated, transforming a network of shallow faults into dextral transform faults (san andreas) (nicholson, 1994). the rotation from 24 ma to 0 ma is represented in the figure below, where mtp is the monterey plate. the faults cut through california land; as a result, the pacific plate’s annual motion 6 cm north with respect to the north american plate in the area is actively splitting the state (marshak, 2008; atwater, 1970) .
extends north of cascadia up to alaska (united states) (rohr, 2000). it connects to the aleutian trench, a subduction zone, which runs south of alaska into the northern margin of the
during the paleogene, greenland sat on a separate plate from the north american plate and they were spread apart. (oakey 2013) however, greenland currently follows the motion of the north american plate, leading to a debate on whether the greenland plate still exists disjointedly. due to lack of evidence, a consensus on the matter has not yet been reached.
