摘要：

The Mars Orbiter Laser Altimeter (MOLA) was used to measure the topography of several putative near-polar martian volcanic craterforms. We believe they were formed by effusive lava shield building eruptions and were not hydromagmatic events, as previously suggested. Furthermore, these craterforms appear to be geologically recent, with ages between 1 and 20 million years, and may provide new evidence of localized thermal anomalies in the upper martian crustal column.
