Strewn amidst the Libyan Desert in southwestern Egypt lie many pieces of the purest natural silica compound found anywhere. This Libyan Desert Glass,
which is very similar to tektites, is another mystery of scientific origin. Many classify it as the result of meteorite impact, yet there are no
impact craters. Like tektites they cannot be classified as obsidian because of their extra-terrestrial makeup. Yet unlike tektites, they seem not to
have been molten or formed into globules. LDG is also uniquely characterized by it's high resistance to heat and does not melt until it reaches
fairly high temperatures.
The argument FOR meteorite impact is that the glass is composed of meteoritic elements...
"Libyan Desert Glass is a natural glass composed of nearly pure silica (98 wt %). The formation of this glass, because of its unusual composition has
for long been considered as mysterious. Chemical analyses show that the glass is locally enriched in meteoritic elements, with typical chondritic
proportions. The only explanation for these observations is that Libyan Desert Glass results from a meteorite impact on a silica-rich target."
However, others believe the chemical analysis disproves meteorite impact...
"The results of a thermal, microstructural, and chemical analysis of LDG suggest that it is more likely derived from a low-temperature chemical
process rather than meteorite impact on sand. "
(McPherson, D., et al; "Was Libyan Desert Glass (LDG) Formed by a Low Temperature Chemical Process?" Eos, 66:296, 1985.)
Another theory suggests they were formed from the surrounding sand heating up after an atomic explosions thousands of years ago.
Along with tektites, LDG has eluded scientists as to unanimously concluding their origin. To this day their origin remains a mystery.
Why should there be such ambiguity to their origin?
Is it not also reasonable to assume, after all the above mentioned reasons, that this Libyan Desert Glass is shattered fragments of the glasosphere
resulting from the penetration of a celestial orb?
