Hi there, I wanted to bring up an issue that I had with the new Calcite and Tuff rock blocks. As a geologist, I have studied petrology and mineralogy and the combination of these with the amethyst cluster makes absolutely no sense. Chemically, amethyst is a quartz (SiO2) while calcite (caCO3) is a nonsilicate, meaning it is nothing like a quartz in formation or chemical composition. It would be more fitting to find calcite at the bottom of the ocean where deposits of dead ocean invertebrates die. These invertebrates actually create their shells and bodies out of calcite, so the ocean is rich in calcium as a result.
Amethyst would be created from metamorphism due to heat and pressure, so its current placement by itself is fine. If you think there should be a block surrounding the amethyst geode, then please use quartzite. it is essentially compressed quartz and is solid SiO2.
Tuff is an exclusively volcanic rock that is formed from ash. it is a sedimentary rock, so it is likely to form at the surface of the world, whether it is in the ocean or on land. Tuff formation may be loosely correlated to amethyst production, but I would be hesitant to place them together, thus implying that these completely different rocks could form under the same circumstances.
I still have my mineralogy textbook, so I do have a reliable source to draw upon. Let me know if this is the wrong place to put this request or if you'd like me to elaborate on what I mean. The implementation of somewhat accurate geology would be a huge deal, not only to me, but to other scientists and children interested in the hard sciences. Giving them an inaccurate image of rock formation may not be beneficial to learning about geology.
