Weathering of Chlorite Illite Deposits in the Hyperarid Qaidam Basin: Implications to Post-Depositional Alteration on Martian Clay Minerals

Frontiers in Astronomy and Space Sciences, 2022
Chlorite is the second-most common class of clay minerals on the Martian surface and has been found to coexist with illite in some regions. Although previous studies have paid much attention to the formation of this assemblage, the post-depositional ...

D/H ratios of the inner Solar System [PDF]

, 2017
The original hydrogen isotope (D/H) ratios of different planetary bodies may indicate where each body formed in the Solar System. However, geological and atmospheric processes can alter these ratios through time.

First mineralogical maps of 4 Vesta [PDF]

, 2012
Before Dawn arrived at 4 Vesta only very low spatial resolution (~50 km) albedo and color maps were available from HST data. Also ground-based color and spectroscopic data were utilized as a first attempt to map Vesta’s mineralogical diversity [1-4]. The

Alkali Metallicity, Mineral Clouds, and Deep Atmospheric Variability on Jupiter

The Astrophysical Journal
The bulk elemental abundances of Jupiter provide critical insights into its formation history and interior structure. Recent observations by the Juno Microwave Radiometer (MWR) reveal a deep Jovian atmosphere significantly depleted in electrons, implying

Stages in evolution of Earth's crust recorded by the Huliaipole block of the West Azov area (4.0-2.0 Ga)

Доповiдi Нацiональної академiї наук України
The U-Pb age of zircon populations from metadacite of the Huliaipole Suite was determined using the LA-ICP-MS method as 3085-2850 and 3700-3360 Ma. In addition, two crystals of zircon were discovered with an age of more than 3800 Ma.

Water-driven Accessible Potential Karstic Caves in Hebrus Valles, Mars: Implications for Subsurface Habitability

The Astrophysical Journal Letters
The Hebrus Valles region on Mars exhibits geomorphological indicators of past aqueous activity, such as fluvial channels and aligned sinkholes. While Martian skylights have mostly been linked to volcanic or tectonic origins, caves formed by water ...

Raman, MIR, VNIR, and LIBS Spectra of Szomolnokite, Rozenite, and Melanterite: Martian Implications

Universe
Different sulfates (Ca-, Mg, and Fe- sulfates) have been extensively detected on the Martian surface. As one of the Martian sulfates, the presence of ferrous sulfates will provide valuable clues about the redox environment, hydrological processes, and ...
