How would you determine that the layer of basalt was an igneous intrusion rather than a lava flow that was extruded out onto the surface?Coconino Sandstone is a geologic formation named after its exposure in Coconino County, Arizona. This formation spreads across the Colorado Plateau province of the United States, including northern Arizona, northwest Colorado, Nevada, and Utah . Vertebrate tracks known as Chelichnus gigas from the Coconino Sandstone in Grand Canyon.

Sandstone was formed from sand that became washed or blown into place and later cemented together by waterborne minerals to become solid rock. Crossbedding refers to a specific type of layering which is noticeable in many sandstone deposits. In the picture above, notice the flat horizontal line and then the layers dipping downward to the …Some thin sandstone layers are affected by the thin mudstone of the adjacent layer, so there is collapse and expansion diameter in the interbedded section of sand and mudstone. From the core of the Shahejie Formation salvaged from underground ( Figure 2 ), the sand and mudstone interbeds in the Shahejie Formation are relatively developed, and ...
