Spatial Water Quality Analysis Of Vadodara District Using Geo Informatics Tools

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

Below these Carboniferous rocks, Devonian rocks are also exposed. These rocks can be found along the northern edge and southeastern margin of the plateau, where strata is nearly vertical. These two geologic systems have also been subdivided into numerous formations categorized according to their lithologic aspect and the fossil fauna and flora which they

NMIT Yan Yean Farm is located in the Northeast of Melbourne, with the latitude of 37° 32’41.416”S and longitude of 145° 5’56.272”E. It is surrounded by rolling hills as well as the Barber Creek that flows through it. In order to observe the geology of the site, Pit 2(UTM: 145° 5.980'E 37° 32.948'S) which is on a flat plain and Pit 3(UTM:-37.54997°N 145.08756°E) is located near the Barber Creek, are chosen.

In layer 6th for this subbasin, both the horizontal and vertical hydraulic conductivities are in large ranges with large values of standard deviations indicating the geologic information of layer 6th in Chowchilla subbasin is not uniform. This shows that are more different soil types in this layer. From the results, the hydraulic conductivities (K1) are in the range from 690 to 0.05 (m/day). According to the third edition of the “Groundwater Hydrology” , David Todd and Larry Mays, page 93, Table 3.2.1, soil types in layer

The youngest of the formations, Point Lookout Formation, sits directly over the Mancos Shale, and is composed of tan sandstone and lenses of shale dispersed in it (“Geology of Mesa Verde, n.d.). The retreating of the sea caused this change in deposition from shale to sandstone; this left it with beach deposits rather than deep water ones (“Geology of Mesa Verde, n.d.). After the sea withdrew completely, about 80 million years ago, a flat coastal plain emerged. Here, swamps developed and as organic and plant material decayed, fine-grained shales formed. These dark brown or black shales are called the Menefee Formation, although thin beds of sandstones and coal can also be found here (“Geology of Mesa Verde, n.d.). The oldest formation, Cliff

Even though, it share similarity to the other region in the Western Northern America province, what make Death Valley unique is the characters of the mountains and desert valleys are in a grand scale than the others. In addition, varies rock type and formation which include volcanic, metamorphic, and sedimentary rocks makes the valley a great place for geological study (Green, 1997, p. 9). Today’s Death Valley we see has taken millions of years to take its present form. In this paper, we examining the geological history of the valley and its alluvia fan formation.

A brief discussion on this journal gave me fresh information to a student like me. One of the information is that shale of all ages has a uniform isotopic composition which made it suitable for the study. From the findings of the research team, they found a silica-rich composition, which is mostly present at the very deep of the Earth. Therefore, plate tectonics happened in the deep during the past. Moreover, I learned that this research is one way of determining the factor that affects the rise in atmospheric

The study marks the first time that researchers were able to compare historical and geological records from the same cave in one place. In addition to recording the cave wall inscriptions telling the centuries-long climate change story, researchers removed sections of the formations in the cave and analyzed the elements and isotopes found inside them. What they found was that periods of drought had strong correlations to large concentrations of certain elements in the fragments.

The maximum erosion was 154.85 km2 during years 2011 to 2013 and maximum accretion was 159.81 km during the years 2013 to 2015. After the year 2013, river accreted a large area, which was eroded mostly during the years 2011 to 2013. Which depicts that lot of sedimentation processes were on going during that time.

The integrated geophysical, remote sensing, isotopic and geochronologic and modelling studies on the Nubian Sandstone Aquifer System have come up with the following findings and recommendations:

The study area lies between Longitude N06°55.389ꞌ - N06°55.384ꞌ and Latitude E003°55.001ꞌ and E003°54.959ꞌ respectively. It lies in the Pre-Cambrian basement complex terrain of South-western Nigeria. The rocks present in Precambrian basement complex are mainly Granodiorite, Porphyroblastic Granite, Migmatite Gneisses, Biotite Gneisses and Hornblende Gneiss. The Gneisses constitute the major rocks by the other groups of rocks. The basement complex is one of the three major litho-petrologic components that make up the geology of Nigeria.

Malda district consists mainly of low lying plains, sloping towards the south with undulating areas on the north-east. Located between latitude 24040’20’’N to 25032’8’’N and longitude 87045’50’’E to 88028’10’’E. The Mahananda River divides the district into two regions. The western region is further subdivided by the river Kalindri into two areas. The northern is known as ‘Tal’- it is low lying and vulnerable to inundation during rainy season, the southern area consists of very fertile land and is thickly populated, commonly known as ‘Diara’. The region of mature alluvium that had given North Bengal its old historical name of varendri or barendri is known today as ‘Barind’. This region is made up of the ancient alluvial humps that are remnants of old riverine floodplains that remain unaffected subsequently by inundation and renewed silting.

The study site is located in Kikori District of Gulf Province (Fig. 1). The site is a logging concession named as Vailala Block 3. The concession is bounded by the big Purari River on the western side and Vailala River on the eastern side. The north tip which the boundary diverts from Purari River uses the ridge tops to join Maropo Creek that flows towards Vailala River. The boundary then continues following the Vailala River until it reaches the coast line.
