朱维斯丘(Jovis Tholus)是火星塔尔西斯区内位于北纬18.41度、西经117.41度处的一座火山丘,直径约58公里,高2990米(9810英尺)[1],其名称取自古典反照率特征[2]

地理和地质

[编辑]

朱维斯丘是一座孤立的小火山锥,位于奥林帕斯山东面和艾斯克雷尔斯山西北,靠近朱维斯堑沟群。山顶附近有一个直径28公里、深达1公里,由五个火山口组成的破火山口[3],距离火山口60公里处坐落了一座直径30公里的撞击坑[3]

这火山丘形成的确切年代尚不清楚,但通过相对定年,间接估计其最小年龄为37亿年,这使其成为一座诺亚纪火山,它的活动不会在赫斯珀里亚纪持续很长时间。因此,由于年代久远,这座火山大部分山体已被掩埋在凸起的熔岩层下[4],这也反映在它的破火山口相对于明显圆锥体的尺寸上。

此外,该火山丘的总体形状值得注意,火山口向西侧倾斜,就好像整个山丘被赫斯珀里亚纪塔尔西斯的抬升所破坏。
