(U–Th)/He thermochronometric mapping across the northeast Japan Arc: towards understanding mountain building in an island-arc setting

open access: yesEarth, Planets and Space, 2020
Topographic relief in arc-trench systems is thought to be formed by plate subduction; however, few quantitative investigations have so far been reported, with respect to the related mountain building process.

Plausible Constraints on the Range of Bulk Terrestrial Exoplanet Compositions in the Solar Neighborhood

open access: yesThe Astrophysical Journal, 2023
Rocky planet compositions regulate planetary evolution by affecting core sizes, mantle properties, and melting behaviors. Yet, quantitative treatments of this aspect of exoplanet studies remain generally underexplored.

Th e age of detrital zircon from metasedimentary rocks of the Ternuvate strata (West Azov block of the Ukrainian Shield)

open access: yesДоповiдi Нацiональної академiї наук України, 2023
The Ternuvate strata comprise metamorphic rocks that make up the Haichur arcuate structure, which is about 72 km long. Its western part lies within the Andriivka fault zone, which separates the Vovcha and Huliaipole blocks, while the eastern part is ...

Salt Distribution from Freezing Intrusions in Ice Shells on Ocean Worlds: Application to Europa

open access: yesThe Planetary Science Journal, 2023
Several icy moons and dwarf planets appear to have hosted subsurface liquid water. Liquid water intruding upwards into the icy outer shells of these worlds freezes, forming ice and (from ocean solutes) non-ice solids.

Iron Mineralogy and Sediment Color in a 100 m Drill Core From Lake Towuti, Indonesia Reflect Catchment and Diagenetic Conditions

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Iron is the most abundant redox‐sensitive element on the Earth's surface, and the oxidation state, mineral host, and crystallinity of Fe‐rich phases in sedimentary systems can record details of water‐rock interactions and environmental conditions ...

Implications of Reactions Between SO2 and Basaltic Glasses for the Mineralogy of Planetary Crusts [PDF]

open access: yesJournal of Geophysical Research: Planets, 2019
AbstractBasalts are ubiquitous in volcanic systems on several planetary bodies, including the Earth, Mars, Venus, and Jupiter's moon Io, and are commonly associated with sulfur dioxide (SO2) degassing. We present the results of an experimental study of reactions between SO2 and basaltic glasses. We examined Fe‐free basalt, and Fe‐bearing tholeiitic and

A GENERIC RIGOROUS SENSOR MODEL FOR PHOTOGRAMMETRIC PROCESSING OF PUSHBROOM PLANETARY IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Currently, each planetary exploration mission team always develops its own software modules to support the photogrammetric processing of planetary images, and as a result of that the main drawbacks are lacking software reusability and the high cost of ...

Stress Chatter via Fluid Flow and Fault Slip in a Hydraulic Fracturing‐Induced Earthquake Sequence in the Montney Formation, British Columbia

open access: yesGeophysical Research Letters, 2020
Source processes of injection‐induced earthquakes involve complex fluid‐rock interaction often elusive to regional seismic monitoring. Here we combine observations from a local seismograph array in the Montney Formation, northeast British Columbia, and ...

Planetary Materials (Reviews in Mineralogy, Volume 36) [PDF]

open access: yesEos, Transactions American Geophysical Union, 1999
Understanding the origin of planetary systems requires our comprehension of the materials from which the planets in our solar system formed. Exploring planetary formation draws from and contributes to a variety of scientific disciplines ranging from astrophysics to geology. One of the methods for understanding the composition and the geological history
