内容記述 | Using topography and gravity data on Mars obtained by Mars Global Surveyor (MGS), crustal and lithospheric thickness are calculated. At first, reference crustal thickness is evaluated, which means the thickness under 0 m elevation, assuming that topography of Hellas region is fully supported isostatically. As a result, the reference crustal thickness of 60 km is obtained. Using that value, lithospheric thickness is calculated. Because the supporting mechanism of topography depends on its wavelength, the elastic thickness can be estimated by investigating relationship between topography and gravity on wavelength domain. The resulting value is about 80 km in volcanic region, and 48 km in northern lowland, which may indicate that the martian lithosphere becomes thinner from south to north as is the case for the crustal thickness. | |||||
