Hello, Timmyhuanghe, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing.

If you have any questions, please don't hesitate to contact me on my talk page. Ian (Wiki Ed) (talk) 03:38, 13 February 2019 (UTC)Reply

Evaluate the Article

edit

The articles on cap carbonate is still a stub. It defines what is cap carbonate and talks briefly about the formation. Everything listed here is related to the topic, but not enough reliable and sufficient information is provided. Although this gives the basic information on the subject, it can't provide a strong overview of this topic. Since I am going to list the article, the following sections would be covered: the origins of the cap carbonate, the formation process and how it is related to snowball earth.Timmyhuanghe (talk) 04:55, 16 February 2019 (UTC)Reply

Introduce Myself

edit

I am a graduate student at Georgia Tech. I am going to edit this Wikipedia page as a final project for my Biogeochemical Cycles class. I will add a few sections to this article, including but not limited to, the origins of the cap carbonate, the formation processes and how it is related to snowball earth. I will keep updating my sandbox for the article weekly. My editing for the article should be done by April 12th. Feel free to give suggestion on my future editing.Timmyhuanghe (talk) 23:06, 17 February 2019 (UTC)Reply
