On May 20, a group of next form Geography students via Meadowbrook Substantial visited the several limestone regions of Lluidas Bono and The Ty Dixon Caverns in St . Catherine, and Moneague in St . Ann’s. I gathered data by way of photography and jotting down significant details. As well as use of the senses, visual being the very best, as well as responsive perception which was also effective.

We went along towards the various halts; I got my remarks and asked questions hence elaborating about what I failed to grasp effectively.

As the tour guide, Mr. Daley, explained the different features, expounded on the formation as well as provided ideas for the SBA composition. This info benefits because secondary data. I faced only one problem which was crossing the panorama in faulty footwear and inclement weather.

Nevertheless I actually managed to get the importance of the areas and their features. I tried to capture the images on the camera as best as Icould, by simply experimenting in different sides, ranges and utilizing close ups for capturing the general importance.

Analysis & Discussion

End 1: Bog Walk Mountainous

Our first stop was along the street within the Swamp, fen, marsh, quagmire Walk Mountainous, located five miles southern of the Bog Walk Community one of the most well-known historic towns in Discovery bay, jamaica. While at this location, it absolutely was evident which the limestone feature formed was composed of natural limestone, for the reason that lighter the rock is at color, is definitely the purer it is composition of limestone is. It was also observed that chemical enduring, the enhancements made on the substance structure and frequently physical appearance of the rock, was acting after the mountain in the form of carbonation. This is the result of rainwater, co2 and limestone to form calcium supplements bicarbonate, a weak carbonic acid which is soluble, making the ordinary easy to break down when it comes in contact with normal water. Clints and Grykes had been evident, while visible in figure 1 . 0, causing weathering. Clints and grykes are a result of carbonation in the weaker important joints and cracks of a rock leaving side rails and lines. The ridges are Clints and the groves are grykes.

The entire stuff is rich with lavish and different vegetation that makes for some remarkable and remarkable scenery. An additional feature produced at the stuff was a cavern, which is a large extensive cave with a deep chamber and interconnecting passages. When the roofing of a give collapses, huge depressions called gorges end result, hence the name “Bog Walk Gorge. The stuff was at first an subway river program which collapsed. The coves on both sides of the overeat seemed to continue to possess probability of collapse. The primary river provides a tributary coming from the Above Dirt District positioned in St . Claire. The major lake processes inside the area are Hydraulic Action, the absolute force of flowing water on the basic of the riv bed, and Attrition, once rocks, transported by the water, smash with each other and break into smaller, smoother particles. End 2: The Bog Walk Bridge

Each of our second end was made with the entrance for the Pleasant Mountain Community, The Bog Walk Bridge; 83. 9 kilometres away from Kingston. Here we examined a bridge which has been oxidizing. This is a reaction in which substances combine with oxygen to form a great oxide: For instance , the combination of iron with oxygen to form an straightener oxide (rust). I saw textures which originated from the mountain range to the decrease parts. These are called interlocking spurs. There was also a flood warning system present as well. It revealed the height of the river and the standard of seriousness to be taken hence flooding must be a threat for this community. Helvétisme basins were observed along the banks to help keep them set up. The breadth of the lake was about 10-13m extensive (at points).

Stop three or more: Lluidas Vale, St . Catherine

Our third stop was at Lluidas Comprobante, worthy Area in St Catherine. Only at that location we all observed a sinkhole which was its primary feature. A sinkhole can be when a joint becomes enlarged to this kind of extent that a deep straight hole is done, down which will a area may go away. A sinkhole was created because of a tributary flowing onto the surface and came upon the land growing upward and eroded the foot with the slope. Overtime, however, the tributary then started to flow underground. Not much water was noticed on the area. The terrain closer to the sinkhole came out somewhat wet. A Polje was noticeable at this area; this is a great elongated depression or pot, formed by synchronization of caves. A polje is found in karstic geological regions of the world, with areas usually five to 500 km. The polje occurs in Troy Formation. This limestone characteristic is out of place by NE-SW trending faults to produce large-scale fault obstructs, which are significant controls around the geomorphology with the area. Geomorphology is the study of landforms and the techniques that shape them. A more recent limoneux and limestone debris cover occurs in the vale, although the steeply sloping edge of the polje to the west, north and east is Troy Development limestone group.

To thesouth and south west of the comprobante, rocks with the Yellow Limestone Group plants out, while further south older cretaceous volcanic and sedimentary strata are revealed. In Luidas Vale operations are completely outclassed by mass is a level of skill area that has been severely worn away so that the comfort is sharpened. The Yellow Limestone Group consists of limestones (Stettin and Chapelton Formations) and clastic rocks (E. g. Guys Hill Formation). The limestone of the Yellowish Limestone Group give rise to doline karsts, with low recurring hills, with the dolines nearby amalgamated to form uvulas in the Stettin Development movements and surface normal water erosion, building a commonly dissected surfaces, this is the Lluidas Vale polje which is produced within a down faulted prevent of Tertiary white limestone and excellent strong strength control through NW-SE trending faults. The ground of the comprobante also definitely seems to be structurally managed in that a series of down-faulted limestone blocks exist and overlain by a series of limestone rubble, bauxitic soils and alluvium which in turn extends to above 30 m thickness.

Lluidas Vale is a Rand- or Border-Polje in that it is not ornamented on all sides by limestone but enclosed to the south simply by volcanic and clastic sedimentary strata of the Central Inliers in the Juan de Bolas Mountains. The latter is the way to obtain the Rj Cobre and Murmuring Brook which movement northwards towards the vale. The Rio Cobre flows north through the hub of the comprobante, but turns abruptly south eastwards and flows a shorter distance along the fault scarp before going. In the polje, the riv and Murmuring Brook are both ephemeral channels flowing simply after rain fall. The north and northwest border in the vale is definitely marked simply by well developed habitacle karst. Many small alluvial fans occur on this section of the vale in heavy clay soils addressing the deposits of limestone dissolution.

Very much lighter limoneux soils arise on the eastern and the southern area of part of the bono due to more frequent surging. The american margin of the vale is definitely marked with a less large slope that contain dolines and small cone-shaped hills grading to structure karsts for the polje. There was also grotte in the place containing stalactites, stalagmites and pillars. A stalagmite is definitely an icicle like deposit of calcium supplements carbonate which will rises through the floor of your cave. A stalactite is another icicle just like deposit of calcium carbonate hanging in the caves roof or developing downward. A pillar is a slender vertical structure of stone employed as a support or to get ornament. These features is visible a diagram 1 . installment payments on your Thelandforms occurred on a west-facing fault scarp above Lluidas Vale polje. The area was also covered with shrubs and natural vegetation mainly closer to the slope.

Stop 4: Ty Dixon

During our take a look at Ty Dixon where tower system karsts, the name provided to all landforms in aspects of limestone, and dolines were evident. A doline is known as a funnel molded or cone-shaped shaped option hollow which can be formed once several shallow holes unite. There seemed to be an eroded highland that left a residual slope forming structure karsts and dolines. The tower karsts seemed approximately 40m extra tall. A tower karst can be isolated sharp sided recurring hills. In the base at the end of the left over hills, there was shallow caverns which were generally covered with shrubs and natural plants. The plants of the area was grown on the smooth areas, where irrigation and accessibility is much better, of generally sugar walking cane while consist of areas, just like on the tower system karsts there have been natural vegetation.

Stop a few: Moneague

Moneague was once one of the largest and the most important cities in St Ann, due to the convenient location over the main North to South. The Moneague Ponds was once located on a flood basic. While at this kind of location houses were visible within close proximity with the ponds. Dust such as forest, trunks and barks could be seen in the pond. The soil was heavily saturated with water (waterlogged) and appeared discolored in color. The water in the pond, even so was lighting azure and reasonably clear. There was clearly natural plants surrounding the pond, this really is evident in plates your five. 0 and 5. one particular

Effect of Limestone

Limestone influences the environment mainly because it induces highly alkaline dusts which are atmosphere pollutants. It also has results on wellness, in particular for those with difficult. The particles also has physical effects within the surrounding vegetation, like it obstructs and damage their interior structures and abrasion of leaves and cuticles, along with chemical results which may impact long-term survival.

Benefit of Limestone

As it provides its effects, limestone even offers its benefits. Adding limestone to drinking water in order to counteract it is called “liming.  When limestone is included with ponds and lakes, it includes the effect of adding calcium supplement and protecting the water coming from becoming too acidic. The main benefit of limestone in this situation is the fact it restores and helps to maintain the ecology of the water and makes this supportive of aquatic your life. It is also a relatively inexpensive method of reducing acidification. Conclusion

In conclusion to my studies, I have discovered the features of limestone inside the areas of examine. Our initially stop was along the Bog Walk Overeat, where the rocks composure was mainly of pure limestone. Chemical enduring was operating upon the rocks resulting in faster decomposition and the creation of clints and grykes. At the second prevent, the Bog Walk Connection, located in the Pleasant Hillside community, it absolutely was observed the community connect was under oxidation. A flood warning system was also obvious, suggesting that flooding is known as a threat to this community. The stop at Lluidas Vale, Valuable Park in St . Catherine, was the most informative 1. Here all of us observed a sink opening formed by a tributary, As well as a polje in Troy formation. To the South and South West with the vale, stones of the Yellow Limestone Group crop out, while even more south older cretaceous volcanic and sedimentary strata happen to be exposed.

In Lluidas Vale processes will be dominated by simply mass can be described as plateau area that has been significantly eroded so the relief is definitely sharp. The floor of the bono also definitely seems to be structurally manipulated. The North and North West edge of the comprobante is proclaimed by well developed cockpit karsts. Much lighter weight alluvial soils occur around the eastern and southern parts of the bono due to more frequent water damage. The western margin with the vale is marked with a less steepslope containing dolines and small conical hills grading to tower karsts towards the polje. There were also caves inside the area that contain stalactites, stalagmites and key elements. During each of our stop at Ty Dixon where tower karsts and dolines were obvious, there appeared to be an eroded highland that left a residual mountain forming tower karsts and dolines. All of us also discovered the Moneague Ponds, which was once a overflow plain and is also now heavily waterlogged. Dirt could be observed in the light green color fish-pond; the garden soil was greatly waterlogged and appeared discolored in color.
