Geology and Minerals
The Late Paleozoic Icehouse, also known as the Late Paleozoic Ice Age (LPIA) and formerly known as the Karoo Ice Age, was an ice age that began in the Late Devonian and ended in the Late Permian, occurring from around 360 to 255 million years ago, and large land-based ice sheets were then present on Earth's surface. It was the second major icehouse period of the Phanerozoic, after the Hirnantian glaciation.
