The Grand Canyon a geologic wonder. Containing many important geologic resources, including a huge fossil record ranging from Precambrian stromatolites to Ice Age mammal bones and dung found in caves a great exploration of geological history ranging from thousands to millions of years. Through relative dating and absolute age determinations we are able to learn a lot from this wonder. Both techniques have value in their own individual situation but when utilized together they are able to develop

The objective of the trip to Blount Springs, Alabama was to observe and gather data on the geological structure of the area. Blount Springs is located in the northern part of Alabama just 33 miles north of Birmingham, and lies on the southernmost part of the Appalachian fold belt. The field work began on the morning of Saturday April, 7th at 8:50am. The weather was cloudy with temperatures in the mid 40’s, and the area was wet from rain the previous night. Our materials included a map of the area

Canada's topography is dominated by the Canadian Shield, an ice-scoured area of Precambrian rocks surrounding Hudson Bay and covering half the country. This vast region, with its store of forests, waterpower, and mineral resources, is being increasingly developed. East of the Shield is the maritime area, separated from the rest of Canada by low mountain ranges pierced by plains and river valleys, and including the island of Newfoundland and Prince Edward Island. South and southeast of the Shield

What is the Canadian Shield? The Canadian Shield is a large plateau that occupies more than 40% of the land area of Canada. It extends from the Great Lakes northward to the Arctic Ocean. This area completely surrounds the Hudson's Bay in a shape of a horse shoe. It is also the largest of Canada's physical regions What is the Canadian Shield made of? The Canadian Shield is mainly made up of igneous rocks that were once mountains millions of years ago. Through the process of erosion, water, ice, glaciers

flowed northeastwards from Uweinat foothills within the Dakhla Basin from Dakhla to Farafa and from Farafra to Bahariya oasis. Provided that the spatial distribution of the high hydraulically conductive sandstones within the Basin, which covered the Precambrian basement slopping northwards. In addition to, the ages of groundwater samples increase progressively along the groundwater flow direction within the Dakhla Basin. Krypton-81 and chlorine-36 (Sturchio et al., 2004; Patterson et al., 2005) show a

soil using this method. 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

The project is located at an elevation of ~730 m above mean sea level and within the Basin and Range physiographic province (BR). The BR is composed of high relief mountains or foothills separated by low-lying valleys and salt flats. The salt flats of the Amargosa do not support plant life, but Phreatophytes (deeply rooted plants) occur on their edges and near the adjacent gravel-dominated alluvial fans. Iodine bush (Allenrolfea occidentalis) grows closet to the salt flats, while saltgrass (Distichlis

will be discussed along with the interpreted depositional environment explaining what we see in the present day. Formation Lithology The oldest rock unit in Boulder is the Boulder Creek Granodiorite which formed 1.7 billion years ago during the Precambrian period. This whitish-grey, intrusive igneous granodiorite is felsic intermediate in composition and has visible crystals of quartz, potassium feldspar, biotite, hornblende and mica. The next formation seen is the Fountain Formation. Fountain Formation

PARIS – A WASTE OF TIME OR A WAY FORWARD? Research has indicated that a warming climate, caused by net greenhouse gas (ghg) emissions is contributing to changes in environment, suggesting that a large average temperature increase could produce irreversible environmental impacts. At the twenty first Conference of the Parties (COP21), 195 international Governments made the first formal universal collaboration, which aims to end what has been dubbed ‘the fossil fuel (Goldenberg & Neslen, 2016). It focuses

Permian age was derived mainly from the San Luis uplift, filled the Rowe-Mora and Central Colorado basins, and lapped onto Precambrian rocks of the other bounding uplifts. The Sangre de Cristo Formation is 700-3,500 feet thick at the south, and 6,000-9,500 feet thick at the north (Baltz 1965). The Sangre de Cristo Mountains are a structurally complex block having a Precambrian igneous core that is bounded by major, high-angle reverse faults and highly contorted, steeply dipping to overturned sedimentary
