Lacui Formation (
Spanish : Formación Lacui ) is a marine
Miocene
sedimentary
formation located in
Chiloé Island with minor outcrops near
Carelmapu on the mainland.

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 .

South of Lacui Formation there are equivalent sedimentary rocks in the islands of
Ipún ,
Lemo and
