Already popular in countries like Australia and Israel, the quartz countertop market is now growing in the U.S, where engineered quartz has a 5% share.
Rocks laid down at the time - some 65.5 million years ago - show a thin layer abundant in rare elements like Iridium, spherules and shocked Quartz that could only have come from a meteorite impact.
