We suggest that intra‐arc rifting accompanied the rapid rotation of the arc during the early Miocene, and that the extensional tectonics and rotation ended simultaneously. 0 votes.

If Pluto had a rapid, violent formation, the heat from the colliding rocks from which Pluto coalesced would have faded relatively quickly, leading the icy shell to grow rapidly, generating, This freezing would pause as heat from radioactivity became a major factor, and resume as radioactive elements broke down, slowly creating, The researchers used thermal model simulations and photographic evidence of, In that scenario, the liquid ocean would slowly freeze over time, although not completely, and cause the, Continental rifting requires the existence of, Post the Definition of extensional to Facebook, Share the Definition of extensional on Twitter, An Editor's Guide to the Merriam-Webster January 2021 Update. googletag.pubads().setTargeting("cdo_pc", "dictionary"); 'increment': 0.5, },{ var pbMobileLrSlots = [ "sign-up": "https://dictionary.cambridge.org/auth/signup?rid=READER_ID", { bidder: 'ix', params: { siteId: '195467', size: [300, 250] }}, { bidder: 'sovrn', params: { tagid: '387233' }}, window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date; iasLog("criterion : cdo_pc = dictionary"); { bidder: 'appnexus', params: { placementId: '11653860' }}, name: "identityLink", iasLog("criterion : cdo_ei = rifting"); 'max': 36, The southern end of the Upper Rhine Graben (URG) is formed by a major continental transfer zone, which was localised by the reactivation of ENE-oriented basement faults of Late Palaeozoic origin. Remnant subsidence modelling usually provides lower-bound estimates due to uncertainties in, The association of these two magma types is an example of bimodal mafic-ultramafic magmatism in a, Several pelitic and semipelitic intervals are present, perhaps indicative of thermal recovery during pauses in extensional, In this case the method will slightly overestimate as some thermal subsidence might be included, but it will underestimate the duration of, Furthermore, the high temperature of the granitic magmas and their intrusion at deep-crustal levels is consistent with magmatism generated by a rising mantle plume in an area of localized, Considering the age of the beginning of the, This lends support to a controlling influence for lithospheric, The evidence, including that of xenoliths carried in the magmas, supports the idea of melting of old metasomatized lithospheric mantle, usually associated with, These characteristics suggest that the initiation of sinistral strike-slip movement behind the trench caused the basaltic volcanism subsequent to, Selecting 100 km gives a conservative estimate as this area has the thinnest lithosphere and will produce the least lamprophyre on, The heavy line indicates the line of initial, Possibilities include there being laterally equivalent parts of a continuous passive margin, or conjugate passive margins following an earlier episode of, This method requires no a priori information about either the duration of, Therefore, the antecedent structures in most cases were not suitably oriented with respect to the external kinematic framework during initial, This thinning may be attributed to orogenic collapse or later. { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_leftslot_160x600' }}, expires: 365 'cap': true googletag.pubads().enableSingleRequest(); an area of flat land near a river that is often flooded when the river becomes too full, Rome wasn’t built in a day: Phrases with place names.
