Time-resolved Raman spectroscopy for in situ planetary mineralogy [PDF]

, 2010
Planetary mineralogy can be revealed through a variety of remote sensing and in situ investigations that precede any plans for eventual sample return. We briefly review those techniques and focus on the capabilities for on-surface in situ examination of ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Remote Compositional Analyses of Space-weathered Lunar Maria

The Planetary Science Journal
Visible-to-shortwave infrared (VSWIR) reflectance spectroscopy has revolutionized our understanding of planetary surface compositions. However, space-weathering processes on airless bodies complicate quantitative compositional analyses.

Thermal history, collisional history, and structure of the CK‐chondrite parent body

Meteoritics &Planetary Science, EarlyView.
Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.
