Station 3: There are three types of cementing agent. They are calcite, silica, and iron oxide. Station 4: Out of the three sand samples, two of them were very alike. They both had a grain size of about 1/10 mm and were beige colored. But one of them was more rounded and had darker grain too. Station 5:In this station we three sandstones. Even though they are all sandstone, they are not cemented with the same cementing agent, and you can tell by the different colors in the sandstones. Station 6: This rock had rippled appearance meaning that they were deposited in marine environment. Station 7: You can tell where the sediments were deposited by observing them carefully. Station 8: We learned from this station that coal is formed from peat through compaction. Peat was brown with light brown spots, tan streaks, and small pores while the coal was black, sparkly with white streaks, and some brown areas. Station 9: There are three types of chert. The red one due to iron oxide is jasper, the multi-colored one due to all the combination of silica, iron oxide, and organic matters is agate, and the grey one due to organic matters is rock gypsum. Station 10: The distribution of sediments are according to the grain sizes. Clay which has the smallest grain size is the bottom layer while gravel which has the biggest grain size is the top layer. Station 11: In some rocks there are tracks of living organisms that used to be there. This is called bioturbation. Station 12: The major methods of preservation or type of fossilization are petrification, mold and casting, carbon film, fossil, and in amber. Station 13: Some animals look like plants and some plants look like animals. Crinoid that looks like a plant under water is actually a plant. Station 14: If a rock reacts with HCl, it is because it has CaCO(little)2. When the HCl is put on the rock, it releases oxygen. Another rock we looked at had many different types of fossil brachiopoded in there. || Station2: In this station we learned about what was friable and what was well cemented we had to do all sorts of strength test. Station3: There are three different types of sandstone specimens and we had to see which ones were the hardest. Station4: at this station he had to draw the three types of sand that we saw under microscope. Station5: the sandstones are different colors but and tells where they came from and what they are made of. Station6: by the rock texture you can tell where it came from which was water Station7: the rocks you cam tell which grains the they came from and the environment. Station 8: At this station we learned how coal was made from other organic materials. Station 9: there are different types of chert and they are made from different materials Station 10: in this station we learned about grain size and the way they are friable Station11: the organic material can be can be left in rocks and can be found everywhere. Station12: this station we learned the ways that fossils can be made and from what material Station13: all animals and plants also get fossilized the same ways Station14: in this station the HCL reacted with the rocks and that meant that it had chemicals inside the rock || 2) This sample ha light componing elements. 3) This sample was made of charcoal. It was compacted into layers. 4) This sample was also made from other materials. It was made out of organic materials; roots, dirts, ect. 5) This was different than the other ones. Carbon was made from it. Type of chert 6) This was made the same way but of iron, and quartz. Type of chert 7) This was te last one made similarly but it was mostly made of quartz as well. type of chert 8)This sample was layered by compaction of charcoal. 9) Clay was compacted making this sample layered. 10) contains silt and was probably under ocean. could contain fossils 11)has crystals but no grains. Made fast 12)Gypsum mineral crystals formed underneath 13)Halite mineral Crystals formed underground 14)sand mixed with mud and hardened 15) easily boroken and breaks to layers 16)large fossils were preserved 17)Rock fragments didnt sort well 18)made in a way to make them sharp 19)large rocks were caught within it 20)fossil shells stuck to the ground and got buried 21)made in sandy area and has quartz 22)rock fragments stuck together making lithic sandstone 23)made with alot of feldspar to give a light color. || Station 2 : I learned the definition of friable and chose which one of the rock samples were friable and which was well-cemented. Station 3 : We observed three different sandstone specimens and found the cementing agent holding each of them together. The cementing agents are silica, iron oxide, and calcite. Station 4 : Two of the samples had similar particle sizes but with different colors. One of the samples had bigger particle size than the other two. Station 5 : The three sandstones in this station had different cementing agents. The colors were different for each sandstone. Station 6 : The sandstone in this station had waves on it. It appeared to be formed in a shallow-nearshore environment. Station 7 : The rocks in this station had to be matched to the particles. They had to be observed carefully in order to be matched correctly. Station 8 : This station shows how coal is formed from the compaction of peat. Coal is darker than peat and is also heavier than it. Station 9 : There are three different types of chert in this staion that are cemented with different agents. Station 10 : The specimen in this station were identified by their order in the tube. The heaviest particles were at the bottom. Station 11 : This station explained how some animals could leave tracks in rocks that can be used to identify the environment from which it came. Station 12 : In this station playdoh was used to show how some rocks can be preserved with mold and cast. Station 13 : Animals and plants have similar ways of being fossilized. Station 14 : The rock reacted with HCL meaning the rock had some chemicals in it that caused the reaction. || ||
