The intense heat of the impact would produce heat-shocked quartz in many types of rock.
撞击所释放的强烈高温会在许多类型的岩石中形成一种热冲击石英。
To date, several such secondary craters have been found along Mexico's Yucatan Peninsula, and heat-shocked quartz has been found both in Mexico and in Haiti.
到目前为止，在墨西哥尤卡坦半岛已经发现了几个这样的二级陨石坑，而且，在墨西哥和海地都发现了热休克石英。
These end Permian fullerenes are also associated with shocked quartz, another direct indicator of impact.
与这些二叠纪末期富勒烯一齐发现的，还有变形石英，即另一个撞击的直接遗迹。
Scientists subsequently found enhanced iridium levels at more than 100 end Cretaceous sites worldwide and shocked quartz at more than 30 sites.
世界各地的白垩纪末期遗址中，科学家发现了超过100处有铱含量高得异常的层位，采集到变形石英标本的遗址也超过30处。
This story, though, raises the question of why there is but a single ejecta layer of iridium and shocked quartz in late Cretaceous rocks around the world.
然而，查特基博士的说法引发了疑问：为什么全球白垩纪晚期岩石中含有冲击石英和铱的喷发物地层只有一层？ 答案或许是，两次撞击是在同时发生的。
