Interior dynamics and thermal evolution of Mars – a geodynamic perspective

چکیده

Over the past decades, global geodynamic models have been used to investigate thermal evolution of terrestrial planets. With increase computational power and improvement numerical techniques, these become more complex, simulations are now able use a high resolution 3D spherical shell geometry account for strongly varying viscosity, as appropriate mantle materials. In this study we review that interior dynamics Mars. We discuss how can be combined with local observations constrain planet's history. particular, recent InSight estimates crustal thickness, upper structure, core size show constraints improve our understanding dynamics, present-day state temperature variations in Our results thickness control surface heat flow elastic pattern, well location melting zones martian mantle. The lithospheric seismic velocities pattern shallow reflect pattern. large leads smaller scale convection than previously suggested. Strong plumes produce melt up times focused Tharsis Elysium, while weaker distributed throughout seismogenic layer, where events occur, discriminate between models, if source depth is known. Furthermore model predictions seismicity compared values measured by InSight. Future need consider from lithosphere at north pole Mars, effects lateral on waves propagation through lithosphere, test spatial distribution comparing observations.

Thermal and crustal evolution of Mars

[1] We present a coupled thermal-magmatic model for the evolution of Mars’ mantle and crust that may be consistent with estimates of the average crustal thickness and crustal growth rate. By coupling a simple parameterized model of mantle convection to a batchmelting model for peridotite, we can investigate potential conditions and evolutionary paths of the crust and mantle in a coupled thermal...

Giant Planet Interior Structure and Thermal Evolution

We discuss the interior structure and composition of giant planets, and how this structure changes as these planets cool and contract over time. Here we define giant planets as those that have an observable hydrogen-helium envelope, which includes Jupiter-like planets, which are predominantly H/He gas, and Neptune-like planets which are predominantly composed of elements heavier than H/He. We d...

features of short story in translated and non-translated literature: a polysystemic perspective

ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...

Mars Thermal Evolution: Aided by Tidal Dissipation?

Introduction: Early models of accretion of Mars [1] suggested long time scales and led to assumed cold post-accretion initial temperatures [2]. But later accretion models [3] gave much shorter time scales and led to the general acceptance of a hot Mars heated by the kinetic energy of impacting planetesimals. Evidence from isotopic studies also seems to require early melting; in particular, Hf-W...
