Lacui Formation (Spanish: Formación Lacui) is a marine Miocene sedimentary formation located in Chiloé Island with minor outcrops near Carelmapu on the mainland.[1][2] Gastropod shells are the most common macrofossils of Lacui Formation.[2] According to Sernageomin (1998) the formation dates to the earliest Serravallian — that is the Middle Miocene.[2]
