By finding and comparing rare collections that span the geologic record, researchers can make guesses about cosmic conditions that Earth experienced throughout its history. Trouble is, the farther back in time geologists go, the harder it is to find well-preserved micrometeorites. “I gave up trying to find them years ago,” said Taylor. “These aren’t tough particles. They’re fragile. Just a little acid etches out their glass, causing them to disintegrate. It’s amazing we find ones this old at all.” Quoted from 「WIRED」

En trouvant et en comparant les collections rares qui couvrent le record géologique, les chercheurs peuvent faire des suppositions sur les conditions cosmiques que Terre a connu tout au long de son histoire. Le problème est, le plus en arrière dans le temps géologues vont, plus il est difficile de trouver des micrométéorites bien conservés. «Je renonçai à les trouver il ya des années», a déclaré Taylor. "Ce ne sont pas des particules difficiles. Ils sont fragiles. Juste un peu d'acide décape leur verre, les obligeant à se désintégrer. Il est incroyable que nous trouvons ceux ce vieux du tout ".

Al encontrar y comparar colecciones raras que abarcan el registro geológico, los investigadores pueden hacer conjeturas sobre las condiciones cósmicas que la Tierra experimentó a lo largo de su historia. El problema es que, cuanto más atrás en el tiempo los geólogos van, más difícil es encontrar micrometeoritos bien conservados. "Me di por vencido tratando de encontrarlos hace años", dijo Taylor. "No se trata de partículas duras. Son frágiles. Sólo un poco de ácido graba a cabo su vaso, haciendo que se desintegran. Es increíble que encontramos los esta vieja en absoluto ".

通过寻找和比较,涵盖了地质记录难得的收藏,研究人员可以对地球经历了其历史的宇宙状况的猜测。麻烦的是,越往回赶地质学家去的,越难找到保存完好的陨石。 “我放弃了试图找到他们几年前,”泰勒说。 “这些都不是艰难的颗粒。他们是脆弱的。只是有一点酸蚀刻出来的玻璃,导致它们瓦解。令人惊讶的是,我们发现那些本老。“

Jeolojik kayıt yayılan nadir koleksiyonlar bulma ve karşılaştırarak, araştırmacılar Dünya tarihi boyunca yaşanan kozmik koşulları hakkında tahminler yapabilirsiniz. Sorun geri jeologlar gitmek zaman içinde uzak olduğunu, o kadar zorlaşır iyi korunmuş micrometeorites bulmaktır. "Ben yıllar önce onları bulmaya çalışırken vazgeçti," Taylor dedi. "Bu sert tanecikler değildir. Onlar kırılgan değil. Sadece küçük bir asit onları parçalamak neden onların camı etches. Biz de tüm olanlar bu eski bulmak inanılmaz. "
