<div class="element">
<div class="element-text">Reddish brown rock made up of pinkish feldspar, colourless quartz, and some dark grey grains. Medium to coarse sand. Moderately rounded. Fairly well sorted.<span> </span><br />Contains <15 vol% clay, so this is an arenite.<span> </span><br />No fizzing with acid, so does not contain significant carbonate.</div>
</div>
<div class="element">
<h3>Thin-section</h3>
<div class="element-text">
<p>Quartz (~65%)<span> </span><br />- Includes fresh quartz grains with<span> </span><a href="/p1acollections/items/show/263">undulose extinction</a>, quartzite grains with internal<span> </span><a href="/p1acollections/items/show/257">sutures</a>, and quartz vein material. Some quartz grains have opaque rims.</p>
<p>Feldspar (~35%)<span> </span><br />- Mainly microcline, some plagioclase. Some<span> </span><a href="/p1acollections/items/show/228">microperthite texture</a><span> </span>and decomposition to clays.</p>
<p>All grains are moderately rounded and fairly well sorted. The rock is well compacted. A thin film of cement mainly hematite and clay coats the grains.</p>

<h3>Rock History</h3>
<div class="element-text">
<p>This rock contains too much feldspar, and the grains are not sufficiently well rounded nor well sorted to have been deposited in an<span> </span><a href="/p1acollections/items/show/167">aeolian</a><span> </span>environment. The sediments were deposited in an aqueous environment.<br /><br /><br /></p>
