The "carbonates" created can be used in making a variety of products, such as glass, resins and building materials.

That finding faced the same hurdles as the finding of magnetites did: no confirmation of liquid water on or near the surface of Mars and the contention that the carbonates were formed in a superhot environment, where no life could possibly exist.

Studies of their microbial descendants, known as cyanobacteria, suggest that these peculiar rocks slowly formed when mats of micro-organisms trapped sediments and precipitated carbonates.

His initial research had shown that the meteorites contained carbonates, which are minerals formed only in the presence of the liquid water needed for life.

The secret is using magnesium oxides instead of calcium carbonates, the main ingredient in Portland cement, the most common type.

The Svalbard expedition has also played a role in the Mars meteorite debate because Steele and Treiman found carbonates with magnetites in them around an ancient volcano there.

The idea that the carbonates were formed in a Martian cauldron is not heard much today.
