This practice sample lab is not intended to submit a tutor’s work as my own. I am stuck trying to figure of the rock types before a huge lab exam next week in my Geology class. This work again, is a practice lab that we have been give to practice before the exam which is work a huge part of our grade. If I can get someone to help me solve and study this PRACTICE LAB I think I should be fine. Thank you! Also these links can be copied and pasted on to google and the website will pop off right there and then.Again, THANK YOU! I hope to heat from you soon! http://geode.net/sedimentary-rock-sample-set/https://learn.vccs.edu/courses/190905/files/45475002/download?wrap=1Question 1Examine sample A.What is the sorting of A?well sortedmoderately sortedpoorly sortedQuestion 2Examine sample A. What is the grain roundness of sample A? very angularsubangularsubroundwell-roundedQuestion 3Examine sample A. What is the composition of sample A?rock fragmentsquartz grainsfeldspar grainsclayQuestion 4Name sample A.brecciaconglomeratequartz sandstonearkoselithic sandstonegraywackesiltstoneshaleclaystonepeatlignitebituminous coalcoquinafossiliferous limestonechalkmicriteoolitic limestonetravertinedolostonerock saltrock gypsumironstonechertQuestion 5Think about the characteristics of sample A, and offer an interpretation for the depositional setting (sedimentary environmentevaporating playa lakehot springsbog or swampglacierdebris at base of cliff / alluvial fanriver channelriver floodplainlakedelta (where a river flows into a standing body of water like a lake or the ocean)sand dunesbeachshallow sea (clastic sediment)shallow sea (carbonate bank)carbonate reefturbidity current (deep sea fan) on the continental slopedeep sea (abyssal plain)Question 6Examine sample B.What is the sorting of sample B?well sortedmoderately sortedpoorly sortedQuestion 7Examine sample B. What is the grain roundness of sample B? very angularsubangularsubroundwell-rounded 8Examine sample B. What is the composition of sample B? (What minerals is it made of?)rock fragments (with hematite cement)quartz grains (with hematite cement)feldspar grains (with hematite cement)clay (with hematite cement) 9Examine sample B. Name sample B.brecciaconglomeratequartz sandstonearkoselithic sandstonegraywackesiltstoneshaleclaystonepeatlignitebituminous coalcoquinafossiliferous limestonechalkmicriteoolitic limestonetravertinedolostonerock saltrock gypsumironstonechert 10Think about the characteristics of sample B, and offer an interpretation for the depositional setting (sedimentary environmentevaporating playa lakehot springsbog or swampglacierdebris at base of cliff / alluvial fanriver channelriver floodplainlakedelta (where a river flows into a standing body of water like a lake or the ocean)sand dunesbeachshallow sea (clastic sediment)shallow sea (carbonate bank)carbonate reefturbidity current (deep sea fan) on the continental slopedeep sea (abyssal plain) 11Think about the characteristics of sample B, and offer an interpretation for the depositional setting (sedimentary environmentevaporating playa lakehot springsbog or swampglacierdebris at base of cliff / alluvial fanriver channelriver floodplainlakedelta (where a river flows into a standing body of water like a lake or the ocean)sand dunesbeachshallow sea (clastic sediment)shallow sea (carbonate bank)carbonate reefturbidity current (deep sea fan) on the continental slopedeep sea (abyssal plain)Question 12Examine sample C.Sample C is a quartz sandstone with red claystone “rip-up” clasts. The red color in the mudstone is due to oxidation of iron in the mud. This implies a depositional setting (sedimentary environment) that was rich in free oxygen.Given that sand is deposited under moderately-energetic current conditions and clay is deposited in low-energy water (i.e., still water), then what does the presence of the claystone “rip-up” clasts surrounded by sandstone tell you about how water energy must have changed at this location when these sediments were deposited (i.e., before they were lithified to make sedimentary rock)?It indicates that the energy / strength of the water currents must have stayed the same over time.It indicates that the energy / strength of the water currents must have decreased over time.It indicates that the energy / strength of the water currents must have increased over time.Question 13Examine sample C.There is a prominent sedimentary structure to be seen in this sampleraindrop impressionsgraded bed(s)current ripple marks (also called “asymmetrical ripple marks”)cross-beddingbimodal cross-beddingwave ripple marks (also called “symmetrical ripple marks” or “oscillation ripple marks”)mudcrack(s) (also called dessication cracks)salt cast(s) (preserved cubic shapes of halite crystals, now formed from sedimentary rock)flute(s)flute cast(s)fossil plant roots (trace fossils)animal burrows (trace fossils)animal tracks, trackways, and trails (trace fossils)body fossils (once-living tissue or skeletal material)Question 14Interpret sample C.Based on the sedimentary structure you identified in the previous question, what interpretive statement can you make about the conditions under which this sediment was deposited?It must have been on the land.It must have been exposed to the air.It must have had flowing currents of water.It must have been deposited in a swampy environment with stagnant water.It must have been in a shallow water environment where waves could reach the bottom.It must have been in the deep ocean, deposited by turbidity currents.Question 15Take another look at the sedimentary structure in sample C.Which way was the water moving when this sedimentary structure formed?from left to rightfrom right to leftQuestion 16Take another look at the sedimentary structure in sample C.Based on the way we understand this sedimentary structure to form, is this sample right-side-up or up-side-down? [Consult Figure 6.12 in your lab manual (page 169-170).] right-side-upup-side-downQuestion 17Examine sample D.Sample D is a graywacke sandstone. Two views are provided: On the left, an original view. On the right, the sample has been flipped and cut into four pieces. Each of the pieces has been rotated around a vertical axis (like looking at the face of a slice of bread). The dark gray color (particularly of the finer-grained portion) is indicative of high levels of organic carbon and dark clay (with reduced iron).What does this implies a depositional setting (sedimentary environment) in terms of its oxygen levels?It indicates that the depositional setting was relatively low in free oxygen.It indicates that the depositional setting was relatively high in free oxygen.Question 18Examine sample D.There is a prominent sedimentary structure to be seen in this sample. raindrop impressionsgraded bed(s)current ripple marks (also called “asymmetrical ripple marks”)cross-beddingbimodal cross-beddingwave ripple marks (also called “symmetrical ripple marks” or “oscillation ripple marks”)mudcrack(s) (also called dessication cracks)salt cast(s) (preserved cubic shapes of halite crystals, now formed from sedimentary rock)flute(s)flute cast(s)fossil plant roots (trace fossils)animal burrows (trace fossils)animal tracks, trackways, and trails (trace fossils)body fossils (once-living tissue or skeletal material)Question 19Interpret sample D.Based on the sedimentary structure you identified in the previous question, what interpretive statement can you make about the conditions under which this sediment was deposited?It must have been on the land.It must have been exposed to the air.It must have had flowing currents of water.It must have been deposited in a swampy environment with stagnant water.It must have been in a shallow water environment where waves could reach the bottom.It must have been in the deep ocean, deposited by turbidity currents.Question 20Take another look at the sedimentary structure in sample D.Based on the way we understand this sedimentary structure to form, is the original sample (i.e., the one at the left side of the screen) right-side-up or up-side-down?  right-side-upup-side-downQuestion 21Examine the loose sand samples E, F, G, H, I, and J.

In other words, the rock is defined by it’s prodigous fossil content.Question 36Compare samples M and N.Both show fossils.
