契克苏卢博白垩纪末期陨石撞击对墨西哥湾和加勒比海Ｋ—Ｔ界面沉积过程产生了重要影响。陨击诱发的海啸和广泛的重力流作用使得Ｋ—Ｔ界面沉积物具有被侵蚀、化石及不同年代岩层互相混合等特征。Ｂｒａｌｏｗｅｒ等（１９９８）称之为Ｋ—Ｔ界面“鸡尾”,并且提出可以将其用于
The Cretaceous Lulob Cretaceous meteorite impact on the Gulf of Mexico and the Caribbean K-T interface deposition process had a significant impact. The tsunami induced by the meteorite and the extensive gravity flow make the K-T interface sediments eroded, fossils and rock layers of different ages mixed with each other. Bralower et al. (1998) called the K-T interface “cocktail” and proposed that it could be used in
