I have removed the following:
"This bias of distribution is thought to have assisted in the tidal locking of the Moon's rotation to its orbit (the phenomenon whereby the Moon spins on its axis in the same timespan as it takes to orbit the Earth). This results in only one side of the Moon being visible from the Earth (excepting some small leeway from libration). The reason the maria have assisted in tidal locking is that they are denser than much of the rest of the surface and are therefore more strongly attracted towards the Earth by gravity. Over many eons, the Moon's rotation has slowed so that the heaviest side of the Moon with the maria on it faces constantly towards the Earth."
This is wrong for several reasons. First, gravitationally, the lunar orientation is just as stable in its current configuration as in a state where it is rotated by 180 degrees. This means that it is only by chance that the mare basalts are predominantly on the hemisphere that faces the Earth. Second, tidal despinning occurs only because of the spherical harmonic degree two gravitational field (this is simply a triaxial ellipsoid in shape). It can be shown that the mare basalts make little to no contribution to the current degree-2 gravitational field of the Moon.

The article gives the pronunciation of mare but not maria; I tend to use MAH-ria, but I can also imagine saying it mah-REE-ah like the woman's name (and certainly this is acceptable Latin pronunciation, cf Ave Maria). Which is it?
The Moon article contains the statement:
This appears to contradict the statement in this article, Distribution section part 4, and possibly the discussion on tidal locking above. I know little about the subject - which is right? Chris55 ( talk) 23:16, 5 June 2012 (UTC)
The Distribution of mare basalts section seems to be quite argumentative, especially during the following section:
I thought that Wikipedia wasn't supposed to have stuff like this in the articles, but I would like some advice before I make any changes. 5donuts ( talk) 19:06, 4 February 2014 (UTC)
Please could our resident experts include information about S-type (red) and T-type (blue) basalts. Cheers. nagualdesign ( talk) 08:54, 1 January 2014 (UTC)
I've seen both of these words used to describe the plural of mare, but which one is correct? 5donuts ( talk) 19:16, 4 February 2014 (UTC)
Hello fellow Wikipedians,
I have just modified one external link on Lunar mare. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Looking at the full Moon one sees a map of Africa. It's true!
Therefore please add a section discussing how does that Africa's size compare with the real Africa?
 OK, with Mare Crisium (176,000 km2) corresponding to Madagascar (592,800 km2), and Mare Nubium corresponding to Liberia, using Google Earth's ruler tool we find the line connecting them on Earth is 7000 km., vs. 2500 km. on the Moon! I.e., I may see a map of Africa on the Moon, but real Africa is three times wider. Jidanni ( talk) 01:02, 26 February 2021 (UTC)
I think the standard view of how the maria formed was from magma migrating up through fractures in the moon's crust. These fractures were likely caused by the asteroid impact that created the basin into which the basaltic lavas flowed. Impact cratering on the lunar farside has nothing to do with it. I would double check the reference. Schaffman ( talk) 15:44, 14 March 2023 (UTC)
