它会根据晶洞的中空程度下沉到一定的高度吗?还是会漂浮在顶部或下沉到底部?大多数晶洞由石英或方解石构成。它们的密度在2.6到2.7 g/cm3之间。为了简单起见，我们把它四舍五入为3。这是水的密度的三倍。< / p >

So, for a geode to float it needs to be at least two thirds empty volume.

But! This is assuming what's inside is air. Geodes form from various fluids or gases. When they formed, if they had a fluid inside, and it is no longer inside, then the geode is not hermetically sealed. This means that once you drop it in the ocean, water will start leaking inside and it will eventually sink. If the geode formed from gas, and it is sealed, then yes there is a chance it will keep on floating.

And could geodes form in the ocean and then break loose and be released into the ocean?

No, because if they form in the ocean, they have seawater inside. Not air. So their density cannot be lower than that of seawater, and they cannot float.
