Hello,
I'm glad to see so much action on #geology today. Ore deposits are an incredible subject and I think it is great that you started to cover it.
If you want to remain active in the scientific community you should start by giving a list of sources you used at the end of the post. Then people can assure that you did not plagiarise. Plagiarism is an important topic, as steemit is a commercial webpage. This goes for image plagiarism as well. All images used in posts should be public domain and labelled for re-use. Your first image has a copyright stamp on it, which is already a bad indicator. Multiple people have written posts about what to do and how to do it. With a little google you should be able to find enough information.
In the end, you can also check out some helpful html commands to help you layout your post and make it more attracting to readers. Here is one example of a list of things.
I hope this helps a little and am looking forward to seeing more of your work.
