Libyan Desert Glass - 3 Grams Tremolite is part of aLibyan Desert Glass (LDG), is a tektite found in the Sahara deserts of Western Egypt, near the Libyan border.

The heat and pressure from this impact would have melted the silica through radiation, similar to the thermal radiation present in a nuclear explosion. Another theory is the bursting of an asteroid as it passes through
