chilled so quickly that the individual minerals have little or no chance to grow. As a result, the rock is either composed of minerals that can be seen only with the aid of a microscope (calledaphanitic, from the Greekaphanēs, meaning “invisible”) or contains no minerals at all (in ...
incompositionfrom granitic to gabbroic. Amphibole, from the Greekamphibolos, meaning “ambiguous,” was named by the famous French crystallographer and mineralogistRené-Just Haüy(1801) inallusionto the great variety of composition and appearance shown by thismineralgroup. There are 5 major groups...
Similarly, social epistemic rhetorics have shown that the making of meaning through writing is a chaotic process conceived of as more complex than ever before. This study concludes that chaos theory resonates within both expressionist and social epistemic rhetorics, allowing for the elusive hope of ...
At the potential –E2, the two characteristics intersect, meaning that the two partial currents of A and B are the same; this does imply that the fraction of A (and therefore of B) is 0.5 only in the case that the number of electrons necessary to reduce the two metals is the same, ...
The condition of low fractions of the A and B elements is the antecedent,X, which is correlated with the consequent,Y, the high value of the target property. While these rules represent correlations and do not imply causation, they have directionality meaning that while antecedent X leads to...
The Allende meteorite is classified as a chondrite.Chondrites take their name from the Greek word chondros—meaning "seed"—an allusion to their appearance as rocks containing tiny seeds.These seeds are actually chondrules: millimeter-sized melted droplets of silicate material that were cooled into ...
Since practically all the solar system's mass resides in the Sun, this similarity in chemistry means that chondrites have average solar system composition, except for the most volatile elements; they are truly lumps of nebular matter, probably similar in composition to the matter from which ...
