Mineralogy and petrology of a lunar highland breccia

Mapping the Spatial Distribution, Mineralogy, and Geochemistry of Lunar Highlands

Introduction: Knowledge of the surface mineralogy and chemistry of the crust is central to understanding the evolution of the lunar crust. Using the 5-band ultravioletvisible (UVVIS) Clementine data set, Tompkins and Pieters [1] showed that approximate mineralogy could be determined from Clementine data and analyzed 109 impact craters detailing the approximate mineralogy, or rocktypes, of their...

Mineralogy and petrology of comet 81P/Wild 2 nucleus samples.

The bulk of the comet 81P/Wild 2 (hereafter Wild 2) samples returned to Earth by the Stardust spacecraft appear to be weakly constructed mixtures of nanometer-scale grains, with occasional much larger (over 1 micrometer) ferromagnesian silicates, Fe-Ni sulfides, Fe-Ni metal, and accessory phases. The very wide range of olivine and low-Ca pyroxene compositions in comet Wild 2 requires a wide ran...

Petrology, Geochronology, Mineralogy, and Geochemistry of the Beemerville Alkaline Complex, Northern New Jersey

The Beemerville alkaline complex, New Jersey, occurs at the western end of the CortlandtBeemerville magmatic belt. The eastern end of the belt is defined by the Cortlandt complex, New York, which largely consists of ultramafic and mafic rocks. Between these two intrusive centers is a linear almost east-west trending zone of lamprophyre and felsic dikes. The Beemerville complex consists of two l...

Petrology and geochemistry of lavas

“This continuity disappears, however, if one considers individual parts of the [Central American] chain and examines separate groups of volcanoes within a restricted volcanic field. It then becomes apparent that the continuity of the province as a whole is the result of grouping excessively large segments of the chain.” A.R. McBirney: Compositional variations in Cenozoic calcalkaline suites of ...
