40Ar/39Ar and cosmic ray exposure ages of plagioclase-rich

 · Argon isotopic data is used to assess the potential of low-mass samples collected by sample return missions on planetary objects (, Moon, Mars, asteroids), to reveal planetary surface processes. We report the first 40Ar/39Ar ages and 38Ar cosmic ray exposure (CRE) ages, determined for eleven submillimeter-sized (ranging from to mg) plagioclase

Shock metamorphism in plagioclase and selective

Plagioclase feldspar is one of the most common rock-forming minerals on the surfaces of the Earth and other terrestrial planetary bodies, where it has been exposed to the ubiquitous process of hypervelocity impact. However, the response of plagioclase to shock metamorphism remains poorly metamorphism in plagioclase and selective amorphization

The minerals included in this group are the orthoclase, microcline and plagioclase feldspars. Relation to Mining. The top states producing feldspar are North Carolina, Virginia, California, Oklahoma, Idaho, Georgia and South Dakota, in descending order of estimated tonnage. Feldspar processors reported co-product recovery of mica and silica sand. Feldspar is mined

Clouding of pyroxene and plagioclase in eucrites

The clouding of pyroxene and plagioclase in the basaltic eucrites ALHA 77302, Juvinas, Pasamonte, and Stannern, is caused by finely disseminated inclusions. This clouding is interpreted to be the result of exsolution of minor components which became incompatible and crystallized on microfractures and other nucleation sites during postbrecciation metamorphism.

Processes and Sources during Late Variscan Dioritic

Processes recorded in plagioclase core compositions include contamination by high 87 Sr/ 86 Sr crustal material and interaction with water-rich magma. The studied samples represent magmas that probably formed either by continuous differentiation and crustal contamination of originally more mafic magmas or by remelting of ∼ 1·3–2·1 Ga basaltic materials in the lower crust. This

Introduction to Rocks — [email protected]

 · Because this cooling process is slow, visible (or, phaneritic) mineral grains have time to form and are usually visible with the naked eye. When any mineral grains in a sample exceed 2 cm in size, the rock is called a pegmatite. Crystalline intrusive igneous rocks are classified based on their underlying mineral compositions (as are equivalent extrusive igneous

Trace element partitioning between plagioclase and melt

 · This experimental plan, which has a long history [, Drake, 1972], is often justified on the basis of the observed difficulty of plagioclase to nucleate, resulting in either no crystals or crystals that are too small to analyze. In the case of set 2, we chose a middle ground wherein the temperature was raised to the point where almost all, but not all, nuclei were destroyed. This

Back-scattered electron (BSE)-derived zoning patterns of plagioclase phenocrysts are used to identify magma processes at Bezymianny Volcano, Kamchatka, based on the 2022-2022 sequence of eruptive products. The erupted magmas are two-pyroxene

Chemical Weathering – Physical Geology

plagioclase + carbonic acid —-> kaolinite + dissolved calcium + carbonate ions. This reaction shows calcium plagioclase feldspar, but similar reactions could also be written for sodium or potassium feldspars. In this case, we end up with the mineral kaolinite, along with calcium and carbonate ions in solution. Those ions can eventually combine (probably in the ocean) to form

Shock metamorphism in plagioclase and selective amorphization

 · Plagioclase feldspar is one of the most common rock‐forming minerals on the surfaces of the Earth and other terrestrial planetary bodies, where it has been exposed to the ubiquitous process of hypervelocity impact. However, the response of plagioclase to shock metamorphism remains poorly understood. In particular, constraining the initiation and

Experimental Constraints on Homogenization of Plagioclase

 · Thus, the controlling process is not dependent on the plagioclase composition. However, it is important to have caution when homogenizing different compositions (different An-content of plagioclase megacrysts) at the same temperature. It is likely that this will lead to over or underheating, thus showing different results for specific major and trace elements. While

Such twinning is one of the most diagnostic features of plagioclase. If the composition surfaces are not parallel to one another, they are called cyclical twins. Shown here is the cyclical twin

Mineral layering in the Twin Lakes granodiorite, Colorado

The Twin Lakes intrusion is composed mainly of coarse-grained porphyritic granodiorite, and is zoned from a felsic core to a slightly more mafic border. Steeply dipping mineral layers, typically a few inches to 5 feet thick and several tens of feet long, occur in discontinuous marginal zones as wide as 5000 feet. Four main types of layers are defined by increased abundances of
