Loss Creek is a river on southern Vancouver Island
, British Columbia, Canada.
The creek runs east-west from north of River Jordan, British Columbia
to Sombrio Beach. It is geologically interesting since the creek follows the Leech River major thrust fault
and forms a distinct border between two different terrane
s: In the south the Crescent Terrane, an ancient volcanic island, and in the north the Pacific Rim Terrane, composed of gneiss
and schist

Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks.-Etymology:...
and schist
Schist
The schists constitute a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, and others. Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is...
