<h2 id="classification">Classification</h2> <ul><li><i>S-tectonites</i> (from the German, <i>Schiefer</i> for schist) have a dominant planar <a href="/facts/Fabric_(geology)/SXCqKBwm">fabric</a> and may indicate a flattening type of strain. This may also be due to a lack of minerals capable of giving a lineation e.g. in a <a href="/facts/Mylonite/eGscFoI4">phyllonite</a>.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a></li> <li><i>L-tectonites</i> have a dominant linear fabric and generally indicate a constrictional type of strain. This may be due to a lack of platey phases.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a></li> <li><i>L-S tectonites</i> have equally developed linear and planar fabric elements and may indicate a <a href="/facts/Plane_strain/j4CJFdsU">plane strain</a> deformation. Many <a href="/facts/Mylonite/eGscFoI4">mylonites</a> are L-S tectonites consistent with a <a href="/facts/Simple_shear/kSPvFWkE">simple shear</a> deformation.</li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Best, Myron G., Igneous and Metamorphic Petrology, Wiley-Blackwell, 2nd ed. 2002, p. 448 <a href="#fnref:1" class="footnote-back-ref">↩</a></p></li> <li id="fn:2"><p>"Tectonite".
