Multitechnique characterization of secondary minerals near HI-SEAS, Hawaii, as Martian subsurface analogues [PDF]

open access: yesScientific Reports, 2023
Secondary minerals in lava tubes on Earth provide valuable insight into subsurface processes and the preservation of biosignatures on Mars. Inside lava tubes near the Hawaii-Space Exploration and Analog Simulation (HI-SEAS) habitat on the northeast flank

Strategies for Deploying a Sensor Network to Explore Planetary Lava Tubes [PDF]

open access: yesSensors, 2021
Recently discovered pits on the surface of the Moon and Mars are theorized to be remnants of lava tubes, and their interior may be in pristine condition. Current landers and rovers are unable to access these areas of high interest.

Islands Within Islands: Bacterial Phylogenetic Structure and Consortia in Hawaiian Lava Caves and Fumaroles [PDF]

open access: yesFrontiers in Microbiology, 2022
Lava caves, tubes, and fumaroles in Hawai‘i present a range of volcanic, oligotrophic environments from different lava flows and host unexpectedly high levels of bacterial diversity.

Tube coalescence in the Jingfudong lava tube and implications for lava flow hazard of Tengchong volcanism

open access: yesInternational Journal of Speleology, 2016
Tube-fed structure occurs as a general phenomenon in Tengchong basic lavas, such as lava tubes, lava plugs and tube-related collapse depressions. We deduced the development of Laoguipo lava flows, which is the longest lava tube (Jingfudong lava tube ...

Enhanced Seismic Backscattering for Lava Tube Detection

open access: yesGeophysical Research Letters
Lava tubes, a common volcanic feature on terrestrial planets, offer critical insights into lava flow processes and may serve as future potential habitats for space crews and other facilities on the Moon and Mars.

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Stability Analysis of Lava Tunnels on Santa Cruz Island (Galapagos Islands, Ecuador) Using Rock Mass Classifications: Empirical Approach and Numerical Modeling

open access: yesGeosciences, 2022
The cavities or lava tubes in the Galapagos Islands were formed by the differential cooling of the basaltic flow of the volcanoes surrounding these islands.

Lunar Pit Craters Presumed to be the Entrances of Lava Caves by Analogy to the Earth Lava Tube Pits [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2014
Lava caves could be useful as outposts for the human exploration of the Moon. Lava caves or lava tubes are formed when the external surface of the lava flows cools more quickly to make a hardened crust over subsurface lava flows.
