Besides morphological proof for ooids on Mars (http://wretchfossil.blogspot.tw/p/putative-martian-microbes-formed.html ), the following is a method for chemical proof for ooids on Mars. The method is to study the chemical compositions of ancient ooids of Earth and compare them with the chemical compositions obtained from the wet chemistry experiment done on Mars (note 1).
The method will confirm that the Martian organics originated from Martian ooids (note 2) rather than from meteorites, because ooids contain biogenic calcium carbonate, fatty acids (note 3), and other organic matter while meteorites do not contain ooids or the combination of calcium carbonate and lipid acid. The only exception is ALH84001 (note 4), but it is a Mars rock, not a meteorite from the standing point of Mars.

 

Note 1: See the April 18 entry in https://ssed.gsfc.nasa.gov/sam/blog.html
Note 2: See ooids from Ogunquit Beach, Mars:

Note 3: “More intriguing still are a handful of longer chain, heavier organic molecules, detected thanks to the ambient bath of leaked solvent. They have defied identification, but may resemble remnants of fatty acids. Life tends to churn out fats in even numbers, with chains 12, 14, 16, and 18 carbons long; finding hints of such a pattern is the biosignature that Mahaffy dreams of discovering.” Quoted from the last sixth paragraph in http://www.sciencemag.org/news/2017/02/mars-rover-steps-hunt-molecular-signs-life
Note 4: See http://wretchfossil.blogspot.tw/2016/04/ooids-found-in-martian-meteorite-alh.html
