The first is the law of superposition, which states that in layers of horizontal sedimentary rocks, the oldest rock layer is at the bottom, and the youngest is at the top (Figure 3.2 ...

Ironstone is a name for any sedimentary rock that is cemented with iron minerals. There are actually three different kinds of ironstone, but this one is the most typical. The official descriptor for ironstone is ferruginous ("fer-ROO-jinus"), so you could also call these specimens ferruginous shale—or mudstone.Jun 2, 2019 · Granite. Andrew Alden. Granite is a type of igneous rock that consists of quartz (gray), plagioclase feldspar (white), and alkali feldspar (beige), plus dark minerals such as biotite and hornblende. "Granite" is used by the public as a catchall name for any light-colored, coarse-grained igneous rock. The youngest rock layers are at the top of the canyon, while the oldest are at the bottom, which is described by the law of superposition. Distinctive rock layers, such as the Kaibab Limestone, can be matched across the broad expanse of the canyon. We know these rock layers were once connected, which is described in the rule of lateral continuity. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. …
