Jarosite is very rarely found on Earth—it is generally seen in mining waste that has been exposed to air and rain. The researchers with this new effort were not looking for it in their ice cores—they were focused on minerals in deep ice cores that might help to better understand ice age cycles. But when they came across the yellow-brown mineral, their interest was piqued. X-ray absorption testing and electron microscopy showed it be jarosite.

The yellow-brown mineral, called jarosite, requires both water and acidic conditions to form. More proof that Mars did in fact have water on it's surface at one time in its past.
Finding Jarosite on Earth might also provide clues to a more turbulent time on Mars. Perhaps meteorites or asteroids colliding with Mars sent chunks of Jarosite into space. As Earth came to its closest distance from Mars, the chunks of Jarosite became trapped by the Earth's gravity as the gravity of the Sun pulled the chunks to the Sun.
Finding the largest source of Jarosite on Mars could be a prime location where water once existed. Determining the overall size of the body of water on Mars where the Jarosite could have come from could be determined by the concentration of water in Jarosite and how much water is needed to form Jarosite.
Finding large quantities of Jarosite on Mars would also be the best location to build on as there could still be water far below the surface of Mars.
