"It is curious that the human mind could blindly accept an infinite speed but had reservations to accept a finite one, simply because it was too large!" ~ Felix Alba-Juez

Geology: The Dolomite Problem

Original post by @mountainwashere

One of the biggest problems that has confronted geology over the years is the dolomite problem. Dolomite is a sedimentary rock of remarkably similar composition to calcite, the mineral that makes up limestone- but rather than being calcium carbonate, it's calcium magnesium carbonate. In rock form, dolomite is also occasionally known as dolostone, but only as dolomite when referring to it in mineral form. It's far from the most exciting mineral on the planet, but it's possibly the most challenging- largely because we don't really understand how it forms.

Transparency

The project tries to be as transparent as possible. For any questions you can reach out to the discord channel.

The initiative and actual selection of posts is done by me, @samve. For sake of convenience I will never upvote my own posts, but since I put effort in writing as well, please give my blog a look and follow me if you would like what you see 😉.

Upvoting and resteeming posts of Geopolis allows us to grow which will results in larger upvotes flowing back to the people creating quality posts = you. All rewards from posts by Geopolis will be used by the community to grow.
