Mysterious, Magical Moldavite　神秘的魔法石－捷克陨石

by Luke Dodds

This little-known and "otherworldly" stone is full of beauty and mystery.
这种鲜为人知的石头来自『另一个世界』，美丽且神秘。

With its strangewrinkled surface, glassy moldavite (捷克陨石) looks like a man-made prop for a science fiction movie. However, the stone occurs naturally and is found scattered across central Europe, from the Czech Republic to Austria to southern Germany. With colors ranging from olive green to brown, moldavite is a rare type of stone called tektite (玻陨石), the origins of _(1)_ are still uncertain. Two main theories have been _(2)_ for their origins. Both place it in outer space.
　　
Amonggeologists , the generally-accepted theory of tektite's origins is as _(3)_. Throughout history, the earth has been struck by countless meteorites that slam into the crust with tremendous speed and pressure. Not quite 15 million years ago, _(4)_ meteorite, enormous in size, smashed into the earth in central Europe. The _(5)_ heat of the impact instantly liquefied the surrounding rocks, and molten rocks were flung high into the atmosphere. The molten materials cooled and hardened rapidly as they fell back to earth, producing moldavite. There are three other tektite fields on earth, and _(6)_ they were all produced by different meteorite impacts.
　　
Another theory, which is less popular, places tektite's origins on the moon. Some scientists have noted similarities between tektite and rocks that exist below the surface of the moon. Some of these rocks reach the surface of the moon through volcanic processes. The theory states that our planet's tektite was actually blasted into space by an enormous moon volcano _(7)_.To end on an even more mysterious note: gem enthusiasts claim the stone's cosmic origins grant it magical powers.

玻璃状的捷克陨石有着皱巴巴的奇特表面，看起来就像科幻电影里的人工道具。不过，这种石头是自然形成的，散布在中欧一带，范围从捷克、奥地利一直到德国南部。捷克陨石的颜色从橄榄绿到棕色都有，是一种十分罕见的玻陨石。其来源尚不明确，不过主要有两套理论曾被提出，而且都认为它是外层空间的产物。
　　
关于玻陨石的起源，地质学家普遍接受的理论如下。综观历史，地球曾被无数陨石撞击过，它们以高速和高压撞上地壳。约 1,500 万年前，有这样一颗巨大陨石撞上欧洲中部的地表。冲击的强烈高温立刻使周围的岩石液化，而熔化的岩石被高高抛到大气层。熔化的物质掉回到地球时，很快地冷却变硬，捷克陨石因而诞生。地球上另有三处玻陨石产地，理论上都是因为不同的陨石冲击而产生的。
　　
另一个理论较少人支持，认为玻陨石来自月球。有些科学家注意到，玻陨石和月球表面下的岩石极为相似。它们有些经由火山运动露出月球表面。这套理论认为，由于某次月球上的火山爆发，被炸到外层空间的岩石落到地球，因而产生了玻陨石。
　　
以一个更神秘的批注来做总结吧。宝石迷们声称由于这种石头来自太空，因而赋予了它神秘的力量。
