Analysis
Chemical analyses of the beads showed they were mostly composed of lead, silicon, and iron. Some of the drops contained significant amounts of zinc, bismuth, and rare earth elements. An analysis of the soil, rocks, and burnt wood taken from the landing ground was also performed. It was noted that the chemical composition was similar to the composition of similar samples taken from the site of the Tunguska event.
The mesh fragments were also analyzed. The material of which the fragments were composed did not dissolve in strong acids and organic solvents, even when exposed to high temperatures for prolonged periods of time. One of the mesh fragments was discovered to be composed of scandium, gold, lanthanum, sodium, and samarium. An analysis of another mesh fragment showed gold, silver, and nickel. After that fragment was heated in a vacuum, the analysis no longer showed these elements; however, molybdenum and rhenium were detected.
The concentration of gold detected in one of the mesh fragments was equivalent to 1,100 g per metric ton. This is much higher than gold deposits in the region, which become economic to extract when the concentration of gold reaches 4 g per metric ton. There are no gold deposits in Dalnegorsk that contain gold at concentrations high enough to extract.

Famous quotes containing the word analysis:
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
“A commodity appears at first sight an extremely obvious, trivial thing. But its analysis brings out that it is a very strange thing, abounding in metaphysical subtleties and theological niceties.”
—Karl Marx (1818–1883)
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
