grauvacas

This, too, was no ordinary rock, but a shard of graywacke or greenstone, a basaltic lava that was perhaps shoved to the surface of the earth 3.5 billion years ago during the Keewatin. Howah!
Esta tampoco era una roca corriente, sino una esquirla de grauvaca o una roca verde, un magma basáltico que quizá emergiera a la superficie de la Tierra hace 3.500 millones de años, durante la Edad de Hielo en la corriente de hielo de Keewatin.
