Painite crystals (in italics) [photograph].

The references look great, but there are still a couple of issues.
1.First, they need to be listed In alphabetical order.
2. Second, I’m not seeing references for your images listed in your references.
For example your figure caption for painite is: Fig 12: Painite Image Credit: crystal-treasure.com
Your citation should also be in the author, year format: Fig 12: Painite (Ziggi, n.d.). I couldn’t find any other name except Ziggi or that specific image, so I’m going to make up part of the reference:
Ziggi. (n.d.). Painite crystals (in italics) [Photograph]. treasurecove.com. URL.
For gypsum, it looks like the image came from the same source as your value information. Since the formatting is different, you would need two Sanz et al. references and each would have a lower case letter letter:
For the value information:
Sanz, J., Tomasa, O., Jimenez-Franco, A., Sidki-Rius, N. (2022). Gypsum. In: Elements and Mineral
Resources. Springer Textbooks in Earth Sciences, Geography and Environment. Springer, Cham.
https://doi.org/10.1007/978-3-030-85889-6_89
For the Photograph if there is no specific person listed as the photographer (I can’t access the book to find out), then:
Sanz, J., Tomasa, O., Jimenez-Franco, A., Sidki-Rius, N. (2022). Gypsum (in italics) [Photograph]. Elements and Mineral Resources. https://doi.org/10.1007/978-3-030-85889-6_89
You can also make other revision besides the references including adding the heading slides and addressing all the information needed.
Can you adding the heading slides and addressing all the information needed.
