Scientific paper

In an electrifying paper published in August, 1996 in the journal Science, David McKay (NASA Johnson Space Center) and his colleagues suggested there were fossils of Martian organisms associated with carbonate minerals in Martian meteorite ALH84001. How these carbonate minerals formed (biologic origin or not) and the temperature at which they formed (low or high) are hotly debated questions. Edward Scott and colleagues have proposed an entirely different origin: the carbonates in ALH84001 formed in seconds at high temperatures (>1000 C) from melts produced during a large impact on Mars 4.0 billion years ago. They infer that it is unlikely that the carbonates or any minerals in them contain mineralogical evidence for ancient Martian life.
