Thanks for that!!
You’re welcome.
As a one-time geology major I found it very interesting, and actually not too surprising, as, here on earth, the green mineral Olivine is commonly associated with the type of rock that Mars bedrock is comprised of. Only thing is, here on earth, it is a highly unstable mineral at the surface and is so easily eroded away through weathering, it rarely appears on the surface. However, since Mars has a very different sort of climate and weathering processes it is able to remain on the surface there, in minor amounts.
