Construct a diagram that illustrates a cross section of six rock units that would account for the features listed below (not in order). Clearly label your units. Remember, these events are not in order—you must determine the order of events based on the descriptions.
a) Rhyolite cross-cuts and covers all units except sandstone.
b) Dark, fine-grained igneous rock cross-cuts and covers conglomerate and older units.
c) Oldest rocks are made of black, biochemical layers that were later tilted.
d) Coarse-grained clastic rock is deposited immediately over coal.
e) Opaque chemical sedimentary rock is deposited directly over basalt.
f) River cuts partially into limestone.
g) Medium-grained clastic rock is deposited over small-grained, high-silica extrusive rock.
