"On the lateral surface, there are small insertions of brown siderite."

Is there any general rule for punctuating sentences like this? Can you give me a source reference?

The link here should explain when to use commas. But the answer to your question : yes should use (,) there to depict a pause as a narrative. It might be acceptable without the comma as well but it will be a just a simple statement. To make it more informative you may use the comma.

Also for comma usage rules - By Grammarly , refer this link.

  • Hello, K. Your first linked article doesn't address this situation. Grammarly has 'When an adverbial phrase begins a sentence, it’s often followed by a comma but it doesn’t have to be, especially if it’s short....' It would be better to add this to an answer. However, this has been covered on ELU before. – Edwin Ashworth Feb 13 '18 at 09:32
  • Hi, Edwin, thanks for the heads up. I answered not just considering the question but also the 'comma-dilemma'. You are definitely right, if it's short we should not put the comma to force-punctuate it. I saw it as a narrative, like they do in Discovery or Nat-Geo; they pause for a second during these situations. My response was with regard to that. I appreciate you pointed out, thanks. Cheers! – K-devlife10 Feb 13 '18 at 11:28
