Barber Creek Observation

One of the major things noticeable from the cross section is that quite a few of the rock layers are over turned, where the older rock layers are above the newer rock layers. This is seen in the contact between the Quartz Monzonite of Papoose Flat and the Campito Formation which is also a disconformity. Next there is some fault zones separating the Camptio, Poleta, and Harkless formations. We then see some more overturned layers with the contacts between Saline Spring Valley Formation (lower and upper members) above the Mule Spring Formation along with some inferred folding. With a normal fault separating the inferred folding event, we see where the overturning occurs. In between the Cambrian layers we see Tertiary Basalt nonconformities also being folded, thus with that we know that the folding event was more recent than the formation of the Basalt. Next there is a large Basalt field with a spot of the Harkless formation. Again we see over tuning as the Basalt field ends there are the Devonian and Mississippian rock Layers on top of the basalt. Separating these overturned layers from the Harkless Formation and the Saline valley Formation (upper member), which are not overturned, is a thrust fault. From this information, there was a major stress event sometime after the Tertiary period causing the rock layers to fold and overturn. And from this stress event and from the folding, normal and thrust faults are formed. Finally we see that there were alluvial and landslide deposits from the Quaternary after the folding, faulting, and over

On October 8th, 2015 our 8-Orange team took a field trip to the Conodoguinet Creek to test the water quality. The Conodoguinet Creek was tested about 2 different times. It was tested about 2 times to take a test to see if the water was polluted or unpolluted. The results will help you understand the conflict of the Conodoguinet Creek.The water came up to about our knees. This trip was different but very informational.

This formation is a very fine grain Mississippian limestone. To test to see if this was the Bangor formation we used HCL and because there was a reaction we know its limestone. This formation could also be described as gray in color as well as an average thickness of 700 feet. We see the Bangor until stop eight, where we see a very different vertical bedding. Also different at stop eight is the outcrop no longer reacts with HCL. From this we gathered that we had moved into the Hartselle formation. In the Hartselle Formation, Mississippian aged sandstones are dominant. This particular stop had a large amount of jointing. After the Hartselle, we figured the Pride Mountain Formation would be next, however at stop nine we see the Maury Formation present. This stop focused on the rock located inside the creek. Because we were unable to go into the creek to get the strike and dips, we once again had to do a projected orientation. Also found on this stop were natural sulfur springs, easy to notice with the smell that it gives off. The Maury formation consist of Mississippian- Silurian aged shale. At the next stop, stop 10, we encounter the Ft. Payne formation. Although this area location was thickly vegetated, we were able to conduct the acid test and saw that the HCL reacts in some places but not all. From this we concluded that this was the cherty limestone of the Ft. Payne formation. The following stop, 12, we went up section and arrived at the Maury Formation once again. At the final stop, location 13, we see Ft. Payne Formation. All of the metamorphism and deformation in the southernmost Appalachians can be related to the movement of the thrust sheets and stacks (Higgins,

With our observation of the Shawangunk formation, we see a sedimentary rock formation containing a range of grain size. Such sizes range from pebbles (3cm-5cm), fine-grain sand, and medium-grain sand. There is some grading towards the bottom left of the outcrop known as a reverse grading with some small cross beds present (Figure 2). The grading occurs towards a slight part of the outcrop where we see the grading beginning as fine grain sediments and working up to coarser grain. With moderate sorting we see variations of degree of sorting per bed. As the degree of sorting varies as does the sphericity. The sediment bedding is well seen ranging in sizes of +/--20 cm to 40 cm. This outcrop has thick beds as one can see the basic units with cracks in between each (Figure 3). With mostly tabular beds consisting of sub-angular, and sub-rounded sediments, this outcrop also consists of some ventricular beds (Figure 4). When looking at figure 4, we have a small space of a ventricular bed present. This is because the bed comes in, pinches thicker bedding,

Bola Creek Track is located within Sydney, New South Wales, within the Royal National Park. This famous heritage listed site holds the title for being Australia’s oldest national park and the second oldest in the world. The field study conducted in the surrounding rainforest of Bola Creek, south end of Lady Carrington Drive, is aimed at assessing and recording data from the area to determine the overall condition of the local ecosystem and the impact human activities are having on the area. Natural flora and fauna abundance and distribution of populations were studied and also the developed adaptations that assists their survival. Observations were recorded on the impact human activities were having on the temperate forest

Around the world our water supply is depleting. Our water is becoming contaminated making it harmful for both mammals and aquatic life. Today over one billion people go without adequate water supply and every fifteen seconds a child dies of waterborne illness. Sources of water that once supplied water to millions can no longer meet the supply and demand of the water need. Scientist predict that the amount of useful water will keep depleting greatly in the years to come. In the next couple of pages it will talk about both the geological and human reasons as to why are water supply is depleting.

Shrimptons Creek Parklands, located in the City or Ryde in the northern Suburbs of Sydney, comprises of seven parks that lie adjacent to Shrimptons Creek. The creek is approximately 3.3 kilometres in length, flowing in a north-south direction through the suburbs of Denistone East, Ryde and Macquarie Park. It is part of the Macquarie Park Catchment which flows through Lane Cove National Park into Lane Cove River. The park’s surroundings consists of low to medium density residential in single dwellings, commercial centres and business institutions.

The South Brae oilfield is mainly Kimmeridgian to mid-Volgian in age, however on some accounts it may possibly be of Oxfordian (Turner et al, 1987). The oilfield is heavily developed along the western, fault-bounded margin of the South Viking Graben approximately 161 miles NE of Aberdeen flanking Fladen Ground Spur (see Fig.1). The Upper Jurassic rifting of the South Viking Graben encountered, pronounced movement along the western bounding fault as syn-rift extension proceeded (Harris & Fowler, 1987, Gregory et al, 2007). Syn‐tectonic deposition throughout the Jurassic ensued the formation of a distinct sediment wedge thinning eastwards into the basin, outlining the main phase of fault movement down the boundary fault (Roberts, 1991). As a result, the Brae oilfields are a series of

Intrusions within the coal-beds in the northern part of the Raton Basin have been destroyed in vast amounts (Johnson and Finn, 2001). Sills and tabular igneous bodies parallel to bedding are intruded in the middle part of the Raton Formation and are exposed in the Purgatoire River Valley (Watts, 2006). Sills within the basin intrude along a coal-bed instead of through the coal-bed, influencing a larger volume of the coal (Rooper et al., 2006). The sills in the basin are fine grained and distributed across the subsurface as well as intruded into the coals (Pillmore, 2003).

Because of the small size, the particles float on the surface of water and often travel long distances during rainstorms. When there are too many of these sediments, the water

The Raton-Clayton volcanic field is about 20 000 km2 in size, and has been active periodically for the past 9 million years. The area is filled with peaks, cones, and lava-capped mesas. The mesas developed as lava flowed into valleys and depressions, cooled off and formed a resistant top layer over sedimentary rocks. As the surrounding rock eroded, the lava protected the underlying stratigraphy from erosion. This caused todays topography, where that which was once the lowest point, is now the highest. There is some disagreement over why the volcanic field is here, one possible cause is that it is near the end of the Jemez Lineament, which has numerous volcanic centers along its reach, possibly
