In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk

The collection of the rocks was based on just picking up the most amount of difference looking rocks that was possible and bringing them home to analyze. This was done for about two months from many difference locations including campgrounds, beaches, rivers, highways as well as construction sites. After about two months there were many rocks so I started to analyze and take out the rocks that were of the same kind. I found many granite, basalt and conglomerate rocks.

There are coarsening-upward sequences preserved, with flooding surfaces represented by low-relief erosional contact of trough-cross-stratification (runnel) upon low-angle planar bedding (swash zone).

The Lynne deposit lies within the early Proterozoic Penokean fold belt of the southern province of the Precambrian Shield. The fold belt is divided into two major terranes in Wisconsin (Sims 1989). The first is the northern Penokean terrane, which contains major oxide facies iron formations and granitic intrusions (DeMatties 1989). The second major terrane, separated from the Penokean terrane by the Niagara fault zone, is the Wisconsin magmatic terrane, characterized by a volcanic island arc-basin assemblage (Sims 1989). This southern terrane lacks major oxide facies iron formations, but contains abundant tonalite-granite intrusions (DeMatties 1989). The Wisconsin magmatic terrane is further subdivided into the northern Pembine-Wausau terrane and the southern Marshfield terrane, which are separated by the Eau Pleine shear zone, a north-dipping subduction zone (Sims 1989).

Emilie Tixeront explains the rock cycle, the formation of the Glasshouse Mountains, and what makes rocks so special anyway.

Next, we can see that the rock displays a subtle porphyritic texture with plagioclase comprising the phenocrysts. The overall texture of the surrounding groundmass is granoblastic equigranular. Under thin section we also see a weakly defined foliation evidenced in the preferential alignment of actinolite grains and to a lesser extent chlorite grains. Undulose extinction is also observed in quartz indicating the rock was subject to deformation. The normalized quartz, alkali-feldspar, and plagioclase (QAP) values of this rock indicate that it is classified as a grano-diorite according to the IUGS QAPF classification system which is consistent with the hand sample interpretation.

As I looked out the window, I saw walls of rocks all over the place. I also saw a lot of good rock exposure on the top of the mountain where the rock was to steep for the snow to stick to. You will notice that Mount Baker has an abundance of all sorts of rocks. From the rocks I examined I observed a lot of extrusive igneous rock, metamorphic rock and sedimentary rocks and you will find few places where you can walk continuously from shale or basalt into well-metamorphosed gneiss (Tabor & Haugerud). I observed rocks such as gabbro, shale, and types of extrusive and intrusive igneous rock such as basalt. The ages of the rocks range from about as old as the mountain, which is about 140,000 years old.

Lyons sandstone can be divided into two distinct types which are the red and grey facies. The red facies are the red- colored sandstone which contains no hydrocarbons and the gray facies are the white to black- colored sandstone which contain hydrocarbon in its matrix (Levandowski,

The Koffler Scientific Reserve at Joker’s Hill is located at the western end of Oak Ridges Moraine (ORM), hence they share common geological features. Therefore, just as in the rest of the ORM, the parent material or bedrock of Joker’s Hill is Ordovician shale and limestone (Johnson et al., 1992). 570 million years ago, what is now southern Ontario was under warm shallow seas (Rock Ontario, 1994, p.49). Between 401-417 million years ago, the sea started to recede and left sand, clay and silt deposits in the region. With time, the materials left behind were compressed into sedimentary rocks. After the retreat of the sea, coral reefs eventually became the coral rocks and the marine species eventually became carbonated rocks--both types of which contain calcium. After long term erosion, the calcium and carbonate rocks became the main composition of the limestone (Goreau, 2006). During the Pleistocene, about 2 million years ago, the Wisconsin glacier advanced across southern Ontario, depositing glacial sediments directly

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,

It is currently the largest exposed granite in the world weighing approximately one trillion pounds; although, only one third of the mountain can be seen as a majority of the mountain expands below ground as far as North Carolina. The enormous pluton mountain, as scientifically identified by geologist, was formed by a complex folding and faulting that had subsequently created the Blue ridge mountains. Though what remains as a mystery to many geologist is as to how such a massive granite mountain has become exposed. Although there are several theories that have been publicated to explain such a phenomena none are substantial or advocated the most. While the origins of Stone Mountain are elusive, the correlations of this landmarks with american history are intricately

Madison group’s rocks date back to the early Mississippian period of the Paleozoic era. The rock units in this area range from the early Mississippian Lodgepole Limestone to the late Mississippian Mission Canyon Limestone. Limestones, and sometimes dolomite stones, are the main lithology of the Madison Group, and they often develop karst topography or the limestone cave with their high solubility characteristic. All of the units in this group have the same warm and shallow marine depositional setting indicated by their richness in fossiliferous rocks. Madison Group has plenty of carbonate rocks occurrences in the Rocky Mountain and Great Plain areas of Western United States. The carbonate rocks, which are common in aquifers, extend from Western

Mr. Hyland is trying to find suitable markets for expanding his granite rock business profitably by relinquishing some control of his business. Mr. Hyland is also concerned with achieving a balance between his local business interests and family life in Canada.
