and has a chemicalcompositionsimilar torhyolite. Obsidian has a glassylustreand is slightly harder than window glass. Though obsidian is typically jet-black in colour, the presence ofhematite(ironoxide) produces red and brown varieties, and the inclusion of tiny gas bubbles may create a golden sh...
Finally, eucrite meteorites, which are highly depleted in volatile elements, are isotopically heavier than chondrites and exhibit negative odd-MIF. The origin of volatile depletion in eucrites has been vigorously debated. We show that Δ199Hg versus Δ201Hg relationships point toward an equilibrium ...
sentences of different length and different structure, because they more clearly express the thought of the whole and state it in a form more in accordance with the mental activity of the hearer. When we have done this, we at the same time secure a variety that avoids monotony.In...
aSince the dawn of time, man has gazed upon the face of the moon in awe and wonder. Our nearest planetary neighbour provoked endless speculation about its origin, composition and influence over our lives. Some of the moon's secrets were revealed after the invention of the telescope but, des...
The model of the origin of the Moon in the circumterrestrial swarm during the active stage of the Earth's growth [1, 2] receives now a support (see e.g. [3]). In this model the feeding substance is the same for both bodies. However two different processes may be mentioned of chemic...
