terrane

Kenny owns a land-surveying business, Terrane, “So I’m around a lot of really nice houses,” he says.

Dubbed the Wrangellia Terrane, after Alaska’s Wrangell Mountains, these lavas are part of a Large Igneous Province formed by volcanoes spewing out huge volumes of lava over hundreds of thousands or millions of years, around 232 million years ago.

Kayama and his team believe the mineral formed on the surface of the moon in the area called Procellarum Terrane, as water originally present in lunar dirt evaporated due to exposure to strong sunlight.

“Plymouth Rock is a glacial erratic at rest in exotic terrane.”

Beneath it is the Little Jack Terrane, and then we’re back down on the Metamorphic Core Domain.
