No doubts left that Mars had a much different atmosphere and wet environment in the past.
Amazing stuff.

One is deposition from sulfur rich volcanic gas.
Second is from the microbial breakdown of gypsum (calcium sulfate).
Mars had volcanic activity, and does have gypsum that formed as its water evaporated. So either of these are also a possibility for the Mar's sulfur as well.

Thanks James! I was not aware of the gypsum microbial path. This just after parfive posted his links for a sulfur eating bacteria genus Thiothrix deep inside the earth. |

There is one Mar's meteorite that there has been a long scientific debate as to what they are seeing in it are fossil bacteria or not.

It's not apparent to me that what has been found on Earth, living and eating minerals very deep underground and inside solid rock many thousands of feet (miles) deep inside the Earth, would be classified as typical bacterial life from what studies I've read. Pretty interesting stuff... maybe one day there will be a deep mine on Mars and we will find out if the same type organisms that are living inside deep rock on Earth are also living deep inside Mars.

Bugs in the basementThere are bacteria known as extremophiles that can withstand extreme conditions, such as deep in the Earth.
I would think that since a lot of gypsum is near or on the surface, and some sulfur deposits are found near or on the surface, that much of this bacterial activity occurs near or on the surface.

Some of the organisms they are discovering are living inside the Earth many thousands of feet below our crust, and are living without oxygen, nor sunlight and eating rock.
The microbes very deep beneath our feet, that have not seen the light of day in possibly hundreds of millions of years, are something to consider in this old universe.
These types of microbes are perhaps descendants from ancient impacts from outer space... the same bringing life to this old planet Earth a long time ago?
I will bet they eventually find similar type microbes living deep underground on Mars... eventually.
