Olympus Mons Fan Shaped Deposit Morphology: Evidence for Debris Glaciers

Introduction: Olympus Mons is the largest volcano on Mars, rising over 25 km above the surrounding plains and with a basal diameter greater than 600 km. It is surrounded by a basal escarpment up to 6 km tall. Extending up to 1000 km beyond this scarp are lobes of ridged materials known as the aureole [1, 2]. Superimposed upon the west and northwest aureole deposits at the base of the escarpment...

Discrete Element Simulations of Volcanic Spreading: Implications for the Structure of Olympus Mons

Introduction: Large basaltic volcanoes, such as Olympus Mons on Mars, and the Hawaiian volcanoes on Earth, are thought to be subject to large scale slope failure and flank collapse, which scatter landslide and avalanche debris (a.k.a., aureole deposits) about the base of the edifice [1], [2], [3], [4], [5]. Volcano growth may also be accompanied by gravitational relaxation of the edifice, refer...

Large-scale Structural Manifestations of Phyllosilicate Generation and Deposition in Early Martian History

Introduction: Recent detections of phyllosilicate (clay) minerals in ancient terrains [1-3] have revolutionized our understanding of early hydrothermal activity on Mars. The spectral signatures of phyllosili-cates are seen exclusively in Noachian-aged outcrops and not in Hesperian or Amazonian materials [1-3]. Phyllosilicates are inferred to have been widely em-placed during a period of time (t...

Debris-covered piedmont glaciers along the northwest flank of the Olympus Mons scarp: Evidence for low-latitude ice accumulation during the Late Amazonian of Mars

We use Viking and new MGS and Odyssey data to characterize the lobate deposits superimposed on aureole deposits along the west and northwest flanks of Olympus Mons, Mars. These features have previously been interpreted variously as landslide, pyroclastic, lava flow or glacial features on the basis of Viking images. The advent of multiple high-resolution image and topography data sets from recen...

Olympus Mons, Mars: Inferred changes in late Amazonian aged effusive activity from lava flow mapping of Mars Express High Resolution Stereo Camera data

[1] Lava flow mapping was conducted on a north-south transect of Olympus Mons using the European Space Agency’s Mars Express High Resolution Stereo Camera (HRSC) image H0037. The HRSC image was coregistered to Mars Orbiter Laser Altimeter, Thermal Emission Imaging System, and Mars Orbiter Camera data, enabling lava flow structures to be differentiated and mapped consistently across the shield. ...
