Regional Similarity of Leveed Lava Flows on the Mars Plains [PDF]

, 2008
The dynamics of lava flow movement are controlled by the fluid interior. Crust, solids, and nondeformable material can only retard the advance or spreading of a lava flow. Figure 1 shows a typical large, channelized lava flow found on the Mars plains. It

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

Journal of Applied Entomology, EarlyView.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

The genesis of a lava cave in the Deccan Volcanic Province (Maharashtra, India)

International Journal of Speleology, 2016
Lava tubes and channels forming lava distributaries have been recognized from different parts of western Deccan Volcanic Province (DVP). Openings of smaller dimension have been documented from the pāhoehoe flows around Pune, in the western DVP.

Is Additive Manufacturing of Dental Zirconia Comparable to Subtractive Methods When Considering Printing Orientation and Layer Thickness? A Systematic Review and Meta‐Analysis

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The aim of this systematic review and meta‐analysis was to determine whether the production of monolithic dental zirconia using additive manufacturing (AM), with consideration of different printing directions and layer thicknesses, enhances its mechanical and physical properties relative to subtractive manufacturing (SM ...

Chemical, Textural and Thermal Analyses of Local Interactions Between Lava Flow and a Tree – Case Study From Pāhoa, Hawai’i

Frontiers in Earth Science, 2020
Because many volcanoes are densely vegetated, understanding of the interactions between active lava flows and trees is essential for robust hazard modeling.

Managing Fractured Ceramic Restorations: Current Evidence and Best Practices—A Scoping Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This scoping review aims to assess the effect of different protocols on the outcome of ceramic restoration repairs. Materials and Methods An electronic search was conducted in three databases (PubMed, Cochrane Library, and Embase), up to July 31st 2025, with previously identified MeSH terms. Results Out of the 2423 records, title and

Moon's volcanic history revealed in glassy spherules from Apollo 17 soil 76501

Meteoritics &Planetary Science, EarlyView.
Abstract Rapidly quenched droplets of pyroclastically erupted lava are common in lunar regolith at landing sites proximal to the maria. Here, we document the U‐Pb chronologies, major element, and trace element compositions of picritic glassy particles from Apollo 17 regolith sample 76501. These particles are dominated by high‐Ti compositions similar to

Elastic Flexure of Young, Overlapping Basaltic Lava Flows Offshore the Galápagos and Hawaiian Islands: Observations, Modeling, and Thermal/Chronological Analysis

Geochemistry, Geophysics, Geosystems, 2020
A recent multibeam bathymetry survey in the Galápagos archipelago revealed a novel observation between the islands of Santa Cruz and Santiago: a steep flexural moat formed between two volcanic flows, nearly 50 m deep and about 500 m wide.

a comparison of morphological and petrological methods [PDF]

, 2013
In planetary sciences, the emplacement of lava flows is commonly modelled using a single rheological parameter (apparent viscosity or apparent yield strength) calculated from morphological dimensions using Jeffreysʼ and Hulmeʼs equations.

Substitution of Fe3+ into anorthite in oxidized, Al‐deficient ferrobasaltic systems with implications for the petrogenesis of angrite meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Angrite meteorites are critically silica‐undersaturated igneous rocks with high Ca/Al and Fe/Mg, along with depletion in volatile lithophile elements Na and K such that they crystallize anorthite along with olivine and calcic pyroxene. The anorthite in angrites contains substantial Fe, and in NWA 1670 and NWA 1296, it is present at major ...
