| Description | Several alternative models were proposed for the origin and mode of formation of channels and valley networks on Martian volcanoes, notably Hecates Tholus, Ceraunius Tholus, and Alba Patera. Early interpretations of Mariner 9 and Viking images suggested that these features on Alba were lava channels, while those on Ceraunius Tholus were interpreted as fluvial or volcanic debris channels. Subsequent mapping of Tyrrehna Patera and Hecate Tholus has suggested that pyroclastic activity may have characterized eruptions on these volcanoes, and that at least for Hecates the channels were probably formed by fluvial erosion of unconsolidated ash deposits on the flanks of the volcano. As part of a continuing program to better understand the eruptive history of the young volcanic centers on Mars, numerous channels were identified on the flanks of Alba Patera that resemble the channels on Hecates. As a result, the possibility is being explored that some of the small channels on the flanks of Alba Patera may be fluvial in origin and potentail water sources and modes of formation are being explored. |
