| 摘 要： | 环形构造是一种常见的地质现象,特别是在月球上分布更为普遍。本文论述了三种成因的环形构造,即:侵入岩成因的环形构造,火山成因的环形构造,以及小天体撞击形成的撞击坑。文中详细介绍了它们的成因与结构特征,指出侵入岩成因的环形构造主要由岩浆冷凝收缩形成,在遥感影像上主要表现为影像色调的不同;火山成因的环形构造为火山口,在遥感影像上具有环形结构;而小天体撞击形成的撞击坑形态复杂,如碗形坑、中心锥环形坑与多环撞击坑,撞击坑的坑沿外缓内陡,遥感影像上表现为环形或弧形构造,有些撞击坑具有辐射纹。 |

| Abstract: | The circular structure is a hackneyed structure,and it is especially universal on the Moon.Three kinds of circular structures of different origins were discussed in this paper: the mechanism of intrusion,the mechanism of volcanism and impact craters caused by the impact of minor bodies.This paper introduced their causes of formation and features in detail and pointed out that circular structures caused by intruded rocks were mainly formed by condensation and subsequent contraction of magma,in remote sensing image they mainly manifest different image tones.The circular structures caused by volcano are volcanic vents,and they possess circular features.Yet,the impact craters caused by the impact of minor bodies have complex conformation,such as bowl crater,ringy crater with center cone and multiring craters.The edge slope of the craters is gentle outside and steep inside.They exhibit ring or arc structures.Some impact craters have radiation lines. |
| Keywords: | circular structure contraction ring of magma impact crater volcanic vent |
