补充资料:喷射物盖层
分子式:
CAS号:
性质:靶岩熔岩和碎块从撞击坑向外抛射,又回落到地面,在坑周围形成一连续的喷射物堆积层。喷射物回落的堆积形态与距撞击点距离、坑大小、靶岩产状、气体或挥发物含量(特别是水)有关。喷射物抛射距离(R)与出射速度(V)和角度(θ)关系:R=(V2/g)sin2θ。45度出射角抛射距离最远,若考虑空气阻力和纬度的重力变化。R值应进行修正。撞击抗周围的喷射物堆积,在坑缘脊处最厚,随距坑缘距离增加而变薄。高出射速度(最高可达5km/s,平均700m/s)和角度(>70 )的抛射物分布的远区,低速低角的堆积在坑缘周围。盖层可延伸到距坑缘约一个坑半径(R),平均半径R∞(2.3±0.5)R1.006。
