New section about polymorphs
I added a new section about the three crystal polymorphs of Calcium carbonate, mainly because I wanted to compare the three and talk about their differences. I talk about structure and their occurences in nature. Maybe this section could be combined with the others ? like the structure section ? I didn't really want to modify others' sections so i created a new one. Also English is not my first language, sorry for any typos. I think I&#39;m a banana tree (talk) 20:26, 15 December 2022 (UTC)
