I don't mean to be grumpy, but this is just a bunch of pretty colors with an unreadable color key. I found the original here. It's high enough resolution to read the descriptions of the map symbols and units.

Yeah, I noticed that too, thanks. The original is great!

rightwingcrazy , you might be crazy but youre right — it is a reduced resolution image with an unreadable legend. When you get the original and blow up the legend, you find the title and premise of the OP article are incorrect . This isn’t a mineralogical map, it is a geographical one showing what areas are covered by ejecta from various craters etc. I didn’t see a single mineral or mineralogically meaningful rock type mentioned in that extensive legend. Essentially the linked article is the equivalent of a low quality blog that didn’t comprehend what the map was.

A better description of the new map (original accompanying article from USGS ) is https://astrogeology.usgs.gov/search/map/Moon/Geology/Unified_Geologic_Map_of_the_Moon_GIS_v2
