Mapping the Growth of Seafloor Carbonates in Deep Time

EarthByte researchers combined their model of plate tectonics with records of carbonate layers logged from cores collected during scientific ocean drilling expeditions. Together, these resources enabled them to estimate the growth and eventual recycling of carbonate deposits through subduction over the last 120 million years.
