Zebra Schist: Geological Wonders of Kangaroo Island

Zebra Schist

Zebra schists are tightly folded, thinly bedded schists derived from sedimentary rocks, which are exposed on Kangaroo Island. The layering, consisting mainly of quartz and biotite, largely reflects the original sedimentary layers rather than metamorphic differentiation, as the secondary biotite helps preserve and outline various sedimentary structures. Small cross-beds, troughs, and climbing ripples in this area indicate a south-facing sequence of Zebra Schist. The Geological Society of Australia has designated this section of the coastline (Zebra Schist) as a geological monument.

What is Schist

Schist is a medium-grade metamorphic rock characterized by medium to large, flat, sheet-like grains that are typically aligned in a parallel orientation. It consists of over 50 percent platy and elongated minerals, such as micas, talc, chlorite, hornblende, and graphite, which are often interleaved with quartz and feldspar. Quartz can sometimes occur in such a way that it forms a distinctive rock called quartz schist. Schist often contains garnet and forms at higher temperatures than phyllite, resulting in larger grains. The alignment of medium to large-grained flakes in a sheet-like orientation within schist is known as schistosity, a type of geological foliation.
