The Olympus volcano on Mars: Geometry and characteristics of lava flows

Neukum, G.; HRSC Co-Investigator Team; Basilevskaya, E. A.

The HRSC (image 0037) and MOC imagery and MOLA altimetry were used to determine the following parameters of the lava flows typical of the southern slope of the Martian volcano Olympus: the length (13-35 km), the width (0.2-4.8 km), and the angles of ground slopes along which these flows advanced (3.4°-6.9°). To measure the thickness of the flows, …

Search for causes of the low epithermal neutron flux anomaly in the Arabia Terra region (Mars)

Head, J. W.; Neukum, G.; Werner, S. +8 more

A geologic analysis of 274 images acquired by the high-resolution MOC camera onboard the Mars Global Surveyor spacecraft within the Arabia Terra low neutron flux anomaly (which is indicative of an anomalously high abundance of hydrogen: up to 16 wt % of the equivalent amount of water) was performed. Correlation between the enhanced abundance of eq…
