- Precambrian Basement Rock - formed 1.8 billion years ago when the continent collided with a group of volcanic islands; intense heat and pressure from the collision formed the metamorphic rock called Vishnu Schist.
- Molten rock from deep within the earth flowed up between the layers of Vishnu Schist to form igneous rock called Zoroaster Granite.
- Bright Angel Shale is found in the flat plateau called the Tonto Platform - formed 515 million years ago when the area was covered by a warm, shallow sea.
- Redwall Limestone - 340 million years ago; up to 500 feet thick; formed beneath another shallow sea.
- Supai Group - shales, limestones and sandstones formed 300 million years ago as the coastline rose and fell.
- Hermit Shale - formed 280 million years ago when the area was covered by a broad coastal plain.
- Coconino Sandstone -formed 275 million years ago from coastal sand dunes.
