V31C:
Magma Channelization across the Solar System Posters


Session ID#: 8936

Session Description:
Understanding magma emplacement mechanisms are important in volcanology, planetary science, and economic geology.  On Earth, much work is being done to understand better how magma emplacement is focused in channels, tubes, and conduits, and the relative roles of construction vs. thermo-mechanical in their formation.  On Earth, it is clear that most magmatic Ni-Cu-PGE deposits and some Cr deposits occur in lava channels and magma conduits, so they also have important economic implications. And across the Solar System, new data from NASA missions continues to reveal more detailed morphological and compositional information about extraterrestrial lava flows.  We propose this session to bring together terrestrial and planetary volcanologists and economic geologists to review the latest results from our various studies, and to identify topics that would benefit from future collaboration and joint research.
