Basalt models for the Mars penetrator mission: Geology of the Amboy Lava Field, California [PDF]

open access: yes
Amboy lava field (San Bernardino County, California) is a Holocene basalt flow selected as a test site for potential Mars Penetrators. A discussion is presented of (1) the general relations of basalt flow features and textures to styles of eruptions on ...

Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance

open access: yesAnnals of Geophysics, 2011
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bends in the flow are considered, as well as the formation

Lunar Mare Lava Flow Dynamics and Emplacement: Predictions of Non-Newtonian Flow Dynamics, Syn- and Post-emplacement Cooling and Volatile Release Patterns, and Vertical and Lateral Flow Structure Development

open access: yesThe Planetary Science Journal
We apply basic principles of magma ascent from deep source regions and its eruption into a low-gravity vacuum environment to develop a theoretical treatment of the fluid dynamics and thermodynamics of mare basalt lava flow emplacement and evolution on ...

Numerical Simulation of Lava Flow

open access: yesPROCEEDINGS OF HYDRAULIC ENGINEERING, 1990
Lava flows are regared as Bingam fluid and its property is explained by rate process which is shown by Arrhenius formula. Then, viscosity and yield steress are shown by exponential functions of temperature.The 1986 lava flows extruded by the fissuer eruption at lzu-Ooshima were repoduced by numerical calculation of two-dimensional unstady flow.

Studies of fluid instabilities in flows of lava and debris [PDF]

open access: yes
At least two instabilities have been identified and utilized in lava flow studies: surface folding and gravity instability. Both lead to the development of regularly spaced structures on the surfaces of lava flows. The geometry of surface folds have been

Erosion versus construction: The origin of Venusian channels [PDF]

open access: yes
Lava channels are a common feature in the volcanic regions of the Moon, and have now been observed on Venus. There has been much debate about the origin of lunar channels as to whether they are the result of erosional (either thermal or mechanical) or ...

Analysis of Vesicular Basalts and Lava Emplacement Processes for Application as a Paleobarometer/Paleoaltimeter [PDF]

open access: yes, 2002
We have developed a method for determining paleoelevations of highland areas on the basis of the vesicularity of lava flows. Vesicular lavas preserve a record of paleopressure at the time and place of emplacement because the difference in internal ...

Minor epic: Notes toward a different “Anthropoetry”

open access: yesAnthropology and Humanism, Volume 51, Issue 1, June 2026.
Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival
