The Pinturas Formation (Middle Miocene) includes a sedimentary succession exposed at the Río Pinturas valley, Santa Cruz province, Argentina. It is separated in three members. The lower and the upper ones were dominated by ashfall episodes with paleosol formation during stability times; while the middle member is represented by desert eolian deposits. Mentioned palaeosols bears a moderately diverse ichnofauna. Trace fossils presents are Coprinisphaera murguiai, C. ispp., Loloichnus baqueroensis,…

IV. Mesoproterozoic Depending on what part of Minnesota you would have been in during the Mesoproterozoic there would have been different things occurring. In Northern Minnesota, the greenstones and granites were eroding away along with the gneiss and granite in north central Minnesota. This erosion created a lot of quartz, which was eventually turned into quartz sandstone (Ojakangas, and Matsch 1982). These quartz sandstones are the Sioux Quartzite of southwestern Minnesota, the Nopeming…

I. Introduction Just north of Saskatoon, Saskatchewan, Wanus kewin Heritage Park provides a window into the past of the plains. For the past 30 some years, there have been continual excavations done and several archaeological discoveries made on this land. Since 2010, Wolf Willow with a Borden designation of FbNp-26 has been the site of the excavations, where a ten metre by eleven-metre hole was dug and methodically excavated by archaeology students from the University of Saskatchewan. This…

The History of the Navajo and Monument Valley The Navajo, or the Diné as they call themselves, have their own story about how they came to Monument Valley, which they call Tsé Bii’ Ndzisgaii or “Clearing Among the Rocks” (Perrottet; “Navajo History”). According to one version of that story, there were four worlds of different colors. On the first world there were some types of insects which made up the “Air-Spirit People,” four beings ruling over the four seas, and four clouds over the sea of…

Earth Science Short Field Based Investigation This scientific report will explain what the primary data that was collected on our field trip to Coomera and Springwood Quarries represents. On the field trip we were given an observation journal to record primary data about the two types of rocks, at Coomera (Nucrush Quarry) and at Springwood Conservation Park. To maintain an equal representation, secondary data will be used to refer to the main points. On our field trip, we went to Nucrush…

Patrick Cardozo Dr Jeffrey Martz Geo 1306 3/24/2017 Second research paper analysis; Evolutionary trends in Triceratops from the Hell Creek Formation, Montana The authors were interested in knowing the actual evolutionary trends in the triceratops from the Hell Creek Formation, Montana; Some previous Palaeontologists have recognised two Triceratops species, Triceratops horridus and Triceratops prorsus, due to the fact that the length and shape of the horns and the size and structure of the…

Mesa Verde National Park is in the Colorado Corner of the Four Corner area. When the Mesa Verde region was uplifted, the streams cut themselves into pediments and divided into two components. One was the McElmo Creek which flows to the west and the other was the Mancos River which drains the cuesta. The Mesa Verde is a cuesta that slopes gently to the south. A cuesta is a hill with a step on one side and a gentle slope on the other. The steep on the Mesa Verde is a 2,000 foot high cliff on the…

The land and rock-based history of Mesa Verde National Park represents diversity as much as the cultural history. Mesa Verde is located in Southwestern Colorado which is one of the four states that is included in the Colorado Plateau. It became a national park in 1906 in order to preserve and protect the famous cliff dwellings and artifacts. Beginning back in 550 A.D to 1300 A.D, Ancestral Puebloans came to realize the diversity of Mesa Verde National Park and used its landscape to create and…

for the mountains in this range is around 3,000 ft. The Appalachian Mountains are surrounded by valleys, which are better purposed for human occupation than other parts of the mountain range. As the top layers of the valley beds are made mostly of siltstones and shales, valleys are more easily eroded away than the tougher sandstone-covered ridges. A significant physical characteristic of the Appalachian Mountains are its ridges: two divisions of the range, the Blue Ridge and the Valley and…

Scope The purpose of this project is to summarize the Montney shale gas play that Progress Energy is operating in. We will be looking at and comparing the different wellbore designs they have, such as lengths, casing sizes, stages, frac tonnage. We will also be analyzing 8 wells in the Lily area and provide thorough information on well architecture, interval problems, number of bits/trips, and a day’s vs depth for all eight wells. We are going to analyze on the eight-well pad, located in…
