The Candelaria Formation is a geologic formation in Nevada, United States . The formation comprises shales and limestones deposited in an open marine environment and preserves fossils dating back to the Induan (Griesbachian to Dienerian) age of the Early Triassic epoch.[1][2][3] Outcrops of the Candelaria Formation are present in the Candelaria Hills southeast of the now abandoned mining town of Candelaria (Mineral and Esmeralda counties), and near Willow Springs (Nye County).[2]
