Scientist’s tell us that ... “The Moon flew off its parent after a giant impact. Because it stayed small, cold and undisturbed it gives a better picture of the past than does its parent. ... The Earth’s turmoil makes it harder to trace its own origin. It’s oldest rocks, found in Greenland and Western Australia are just under four billion years old.”
Easily one of the most laughable theories purported by ‘scientists’

I found this at www.lei.usra.edu
“What evidence is there of volcanism on other planets?
Moon:  Our closest neighbor has small volcanos, fissures (breaks in the crust), and extensive flows of basalt, a fine-grained dark volcanic rock. The large dark basins that you can see on the Moon are the maria — areas of these lava flows. However, all these volcanic features are old. There are no active volcanic features on the Moon. Most of the volcanic activity took place early in the Moon’s history, before about 3 billion years ago. The most recent lava flow occurred about 1 billion years ago.”
From your second link:
"The researchers hint that they may also be volcanic in origin."
"Without further studies it’s difficult to determine the exact origin and ages of these lunar formations."
