Alayer of sedimentary rock lies next to a layer of igneous rock. if inclusions from the igneous layer are scattered in the sedimentary layer, then the layer of sedimentary rock is than the igneous layer.

A layer of sedimentary rock lies next to a layer of igneous rock. If inclusions from the igneous layer are scattered in the sedimentary layer, then the layer of sedimentary rock is richer in minerals than the igneous layer.

Explanation:

The igneous rocks are a good source of minerals like pyroxene, mica, amphibole, olivine, etc. Some common minerals like quartz, feldspar and muscovite are found in both igneous and sedimentary rocks.But the major clay minerals like calcite, gypsum, dolomite and halite are only found in the sedimentary rocks. Thus, scattering inclusions from the igneous layers over the sedimentary layer would make the sedimentary layer richer in minerals
