Mineralogy and Surface Composition of Asteroids [PDF]

open access: yes, 2015
Methods to constrain the surface mineralogy of asteroids have seen considerable development during the last decade with advancement in laboratory spectral calibrations and validation of our interpretive methodologies by spacecraft rendezvous missions ...

The Fourier transform infrared spectroscopy (FTIR) analysis for the clay mineralogy studies in a clastic reservoir

open access: yesJournal of Petroleum Exploration and Production Technology, 2022
The complete characteristics knowledge of clay minerals is necessary in the evaluation studies of hydrocarbon reservoirs. Ten samples taken from two wells in a heterogeneous clastic gas reservoir formation in NE Iran were selected to conduct the ...

Modeling dust mineralogical composition: sensitivity to soil mineralogy atlases and their expected climate impacts

open access: yesAtmospheric Chemistry and Physics, 2023
. Soil dust aerosols are a key component of the climate system, as they interact with short- and long-wave radiation, alter cloud formation processes, affect atmospheric chemistry and play a role in biogeochemical cycles by providing nutrient inputs such

Olivine-Carbonate Mineralogy of the Jezero Crater Region [PDF]

open access: yesJournal of Geophysical Research - Planets, 2019
A well‐preserved, ancient delta deposit, in combination with ample exposures of carbonate outcrops, makes Jezero Crater in Nili Fossae a compelling astrobiological site.

Mineralogy of Vera Rubin Ridge From the Mars Science Laboratory CheMin Instrument

open access: yesJournal of Geophysical Research: Planets, 2020
Vera Rubin ridge (VRR) is an erosion‐resistant feature on the northwestern slope of Mount Sharp in Gale crater, Mars, and orbital visible/shortwave infrared measurements indicate it contains red hematite.

Soil Color and Mineralogy Mapping Using Proximal and Remote Sensing in Midwest Brazil

open access: yesRemote Sensing, 2020
Soil color and mineralogy are used as diagnostic criteria to distinguish different soil types. In the literature, 350–2500 nm spectra were successfully used to predict soil color and mineralogy, but these attributes currently are not mapped for most ...

An evolutionary system of mineralogy. Part I: Stellar mineralogy (>13 to 4.6 Ga)

open access: yesAmerican Mineralogist, 2020
Minerals preserve records of the physical, chemical, and biological histories of their origins and subsequent alteration, and thus provide a vivid narrative of the evolution of Earth and other worlds through billions of years of cosmic history.

The influence of particle shape and mineralogy on the particle strength, breakage and compressibility

open access: yesInternational Journal of Geo-Engineering, 2020
It is widely accepted that both particle shape and mineralogy could have a great effect on the particle strength. However, due to the complexity of nature grains, it is difficult to distinguish the influence of particle shape from mineralogy.
