<blockquote>
<p>Alluvial: Detrital material which is transported by a river and usually deposited along the river's pathway, either in the riverbed itself or on its floodplain.</p>
<p>Colluvial: Weathered material transported by gravity action such as on scree slopes.</p>
<p>Eluvial: Weathered material still at or near its point of formation.</p>
