隕石拍賣 (Meteoriten Haus Collection)

利比亚沙漠玻璃（LDG）是在两千八百万年前形成的，当时一颗巨大的陨石击中了撒哈拉大沙海的砂岩地层。撞击地面时，动能在一次巨大的爆炸中释放，气化了陨石和周围地表。热量把砂岩熔化，现今被发现为冲击玻璃。LDG 已被用于在早期石器时代制工具。在新石器时代，制作了精细的刀片和刮器。最著名的用 LDG 制成的珠宝是法老图坦卡蒙胸饰上的圣甲虫。

Libyan Desert Glass (LDG)  was created 28 million ago, when a big meteorite hit the sandstone formation at the great sand see in the Sahara.
By hitting the ground the kinetic energy was set free in a huge explosion that vaporised the meteorite and the surrounding earth surface. The heat melted the Sandstone that is now found as impact glass. LDG has been used for making tools already in the early stone age. In the Neolithic times fine blades and scrapers have been made. The most famous piece of jewellery made from LDG is the scarab in the pectoral from pharaoh Tutankhamen.
