characteristics of the domes to estimate the yield strengths (� 10 5 Pa), plastic viscosities (� 10 9 Pa s), and effusion rates (� 50 m 3 /s) of the magmas which formed them. These values are similar to those of terrestrial rhyolites, dacites, and basaltic andesites and support the hypothesis that these domes are an unusual variation of typical highlands and mare compositions. The dikes which formed them are predicted to have had widths of � 50 m and lengths of about 15 km. The magma rise speed…

Lunar red spots: Stratigraphic sequence and ages of domes and plains in the Hansteen and Helmet regions on the lunar nearside

[1] Basaltic mare materials extruded between ∼ 4 Ga and ∼ 1.2 Ga ago and formed large expanses on the lunar nearside. In contrast to the maria, volcanic shields, domes, and cones also occur but cover

The nature and origin of Mafic Mound in the South Pole‐Aitken Basin

“Mafic Mound” is a distinctive and enigmatic feature 75 km across and 1 km high near the center of the vast South Pole‐Aitken Basin (SPA). Using several modern data sets, we characterize the



Ascent and eruption of basaltic magma on the earth and moon

Geological and physical observations and constraints are applied to the development of a model of the ascent and emplacement of basaltic magma on the earth and moon. Mathematical models of the nature

Gruithuisen domes region: A candidate for an extended nonmare volcanism unit on the Moon

Small lunar areas known as red spots are thought to represent good candidates for nonmare volcanic units predating or contemporaneous with the period of mare volcanism. In this study, we present

Viscoplastic Models of Lava Domes

It is proposed that lava domes possess a yield strength whose magnitude governs their shape and explosivity. Theoretical and laboratory modelling of the spread of viscoplastic material over a

Formation of Tertiary Crust on Venus by Remelting of Tessera Crustal Roots: The Ovda Regio Festoon

Tertiary crust forms by the reprocessing of primary and secondary crusts by several possible mechanisms; according to Taylor [I] the Earth's continental crust is the only presently known example of

An unusual volcano on Venus

Materials that issued from an unusual Venusian volcano produced (1) a complex domical structure about 100 km across with thick, broad flow lobes up to 41 km wide, (2) an extensive sheet of thick

A preliminary analysis of a global survey of Magellan data covering over 90% of the surface and designed to document the characteristics, location, and dimensions of all major volcanic features on

Nature of Local Magma Storage Zones and Geometry of Conduit Systems Below Basaltic Eruption Sites: Pu'u 'O'o, Kilauea East Rift, Hawaii, Example

The fluid dynamics of the well-documented eruptive episodes at Pu'u 'O' o, Kilauea (Wolfe et at., 1987) are used to investigate quantitativeely the size and shape of the shallow conduit system
