当星球冷却后，覆盖其表面的岩浆海洋开始定形。
As it cooled, an ocean of magma covering its surface began to crystallize.
夏普认为最好的解释就是：月球的岩浆海洋中几乎不存在氢元素。
The best explanation, Sharp says, is that there was hardly any hydrogen in the moon's magma ocean.
他们提出，也许月球甚至从未存在过岩浆海洋或以另一种方式形成的岩石。
Perhaps the moon never even had a magma ocean and the rocks were formed another way, they suggested.
在月球冷却之前，它的表面有一个所谓的岩浆海洋-熔融岩，有保持大量水的能力。
Before it cooled, there was a so-called magma ocean on the Moon's surface - molten rocks, capable of retaining high quantities of water.
若非如此，月球可能从来都没有出现过岩浆海洋。之前科学家们曾认为，月球形成后不久，其表面处于岩浆的状态。
Or, if not, the moon may never have had the magma ocean that scientists think covered its surface soon after it formed.
该研究团队说，这个发现提示了创造月球的碰撞可能发生在以前所设想时间之后，或者月球上岩浆海洋在早期并没有覆盖月球的表面。
The team says this hints that the impact that created the moon may have happened later than previously thought or that a magma ocean did not cover the early moon's surface.
根据轨道数据资料，月球早期岩浆海洋的迹象显示了月球上含有丰富的斜长石，它是一种从岩浆中结晶出来、并漂浮在岩浆顶上的轻矿物。
Evidence for an early lunar magma ocean comes from orbital data showing an abundance of plagioclase, a lightweight mineral that crystallises from and floats to the top of magma.
岩浆大量涌现，在一些地方形成了广阔的熔岩海洋。
Magma appeared in abundance and in some locations formed vast molten oceans.
因此一个行星表面大部分的微量水元素到达岩浆的表面就凝固了，这将足够形成像地球上这样的海洋。
Thus, if the majority of the small amounts of water in a planetesimal reaches a planetary surface as its magma solidifies, this would be enough to form oceans that are similar to Earth's.
这不是由赤道处更深的海洋和更多的水体所引起的，而是地球本身的形状，特别是其岩浆层引起的。
This is not caused by deeper oceans, more water, at the Equator but rather the shape of the Earth itself, the magma layer in particular.
边缘海洋壳是玄武岩浆侵入并吞蚀破碎的大陆边缘地壳后形成的不同于大洋壳的新型洋壳。
The marginal sea crust is another kind of oceanic crust, which was formed after the basalt magma engulfed and devoured the tattered continental margin crust.
那里是由岩浆形成的，在某些地方是由海洋来支撑的。
Formed from volcanic lava flows which in some places are supported by the ocean.
