minerals can have controlled compositions, they are often viewed as "unnatural". Here, we show how trends in the interaction of RNA with natural mineral specimens, synthetic mineral specimens, and co-precipitated pairs of syntheticminerals, can make a persuasive case that the observed interactions reflect
sulfate minerals, where those trends are the same when measured in natural and syntheticminerals. They are also validated by comparison of co-precipitated syntheticminerals. We also show differential binding of RNA to polymorphic forms of calcium carbonate, and the stabilization of bound RNA on
aragonite. These have relevance to the prebiotic stabilization of RNA, where such carbonate minerals are expected to have been abundant, as they appear to be today on Mars.
