Exercise 4 depositional environments 2. what does the red color suggest about the envi procedure ronment of deposition? figures 4.7 through 4.12 show outcrop images of mesozoic formations from central utah along with sedimentary data collected at each locality. careful- ly study the images and accompanying information. compare outcrop data with information provided 3. rocks of the north hom formation were most in table 4.1 to determine the depositional environ ment in which each of the formations was formed. answer all of the accompanying questions. likely deposited in which of the sedimentary environments listed in table 4.1? explain your part a north horn formation, cretaceous, red narrows, utah (figure 4.7) 1. what is the dominant sedimentary rock type shown in figure 4.7? 05 m cretaceous north horn formation, utah rock type: conglomerate with interbeds of sandstone composition: boulders, cobbles, and pebbles comprised of sandstone and limestone. matrix comprised of quartz, lithics, and mud texture: poorly sorted, large clasts subrounded, sand-size material angular to subrounded color: red to reddish brown sedimentary structures: thick-bedded with primary dips of a few degrees to the east; gravel-filled channels fossils: none regional trend: formation is over 2,000 feet thick in centra utah; it becomes thinner and finer-grained to the east 1 m figure 4.7 cretaceous north horn formation, utah
