Sinuous collapse chains and skylights in lunar and Martian volcanic regions have often
been interpreted as collapsed lava tubes (also known as pyroducts). This hypothesis has …

▪ Abstract Mantle plumes are recognized by domal uplift, triple junction rifting, and especially
the presence of a large igneous province (LIP), dominated in the Phanerozoic by flood …

Although the majority of volcanic and tectonic activity on Mars occurred during the first 1.5
billion years of its geologic history, recent volcanism, tectonism and active seismicity in …

Large igneous provinces are exceptional intraplate igneous events throughout Earth's
history. Their significance and potential global impact are related to the total volume of …

Earth history is punctuated by events during which large volumes of mafic magmas were
generated and emplaced by processes distinct from “normal” seafloor spreading and …

▪ Abstract Earth, Venus, and Mars all exhibit populations of giant (radiating, linear, and
arcuate) mafic dike swarms hundreds to> 2000 km in length. On Earth the dikes are exposed …

The northern plains of Mars cover nearly a third of the planet and constitute the planet's
broadest region of lowlands. Apparently formed early in Mars' history, the northern lowlands …

Seven possible skylight entrances into Martian caves were observed on and around the
flanks of Arsia Mons by the Mars Odyssey Thermal Emission Imaging System (THEMIS) …

Hundreds of ancient lake basins detected on Mars via orbital remote sensing represent rare
oases of hydrosphere–atmosphere–lithosphere interactions with great astrobiological …

The earliest history of the Moon is poorly preserved in the surface geologic record due to the
high flux of impactors, but aspects of that history may be preserved in subsurface structures …
