Question
Acient Envinonments 13. As a micropaleon tologist working for a major oil company, your job is to count likely to foraminifera shells and determine which units are from environments I proxduce oil. Benthic forams may have shells formed of calcite or shells formed by cementing sediment parti intertidal marshes. Forams with calcareous shells are from more shallow utinated forams tend to live in environments where there is less terrestrial sediment. Planktonic forams will be abundant in more open water. Units A-F are marine sedimentary rocks. The number entages of each and type to complete the chart, then use this information to correlate the columns answer questions 14-16. Unit 283 152 58 18 35 75 0 28 79 25 240 24480 F278 17 0 Correlate the columns below by facies (not by letters): West East sediment. Which unit is the best candidate for producing oil?Explanation / Answer
14) The oil production of any unit is greatly depends upon the components or the composition of many organic as well as inorganic substance. The component may be varied in the ratio of organic to inorganic but if in case the percent of organic components are more, the unit will be suitable to choose as the oil production unit. In the above situation the unit C is having a good percentage of organic composition which can be effective to produce oil.
15) in the above context of correlation we would be try to explore the oil in the west direction. It is because to the fact that if We take the case of west side, we can find the unit that is C which having the suitable percent of components and which would be beneficial to obtain a good and large quantity of oil. As this is to the west side so we will explore to the west.
16) if we take the case of how The faces change with respect to time than here we can see that the unit in the top of the list are having increase in the compo of organic mattera. Similarly in the buttom section it is decreases. So the net rate of change is transgressive sequence.
18) in the west of united, the map have the mountains on the line of ranges of the zero representation. In this section as there's a deposition of sediments and thus it a formed of the mountain formation. And this can be taken as the evidence for this.
19) in the map, the oceans are ThisThose parts which are having the representation of marine shale. As it is denoted with 3 so in map the three named regions are ocean ranges.
20) periods of rock formations -
As it is directed from the above figure so here we are having The period for this
1-2 billions years ago
2-1.5 biLlions yrs ago
3-1.5 million yrs ago
4-1 million years ago
5-.5millions yrs ago.
