Sedimentary rock

Jessica Vandeventer Science 156 29 September 2016 Sedimentary Rock Formation Purpose/Question- The purpose of the lab allows us to look at steno’s principals and study the process of lithification, transgression, and regression. Hypothesis– If I follow Steno’s principals in making rock layers, then I will be able to see the process of lithification. Analysis Questions - A. Did your sequence of rock layers follow Steno’s three principles? Explain why or why not. The law of superposition says that undisturbed rock layers are going to be from oldest to youngest. The oldest is going to be at the bottom. Original Horizontality is where the layers of rock are going to be deposited horizontaly. The third principal is cross-cutting. This says that…

Strata Essay In the diagram given, fossil "C" is the oldest out of fossil "B" and "A"mane they were all found in sedimentary rock. In between each fossil there were events that occurred that left layers behind, like a volcanic explosion. From this diagram, you can predict the relative ages of each strata and fossil. Before fossil "C", there was volcanic ash, then A layer of sedimentary rock, then more volcanic ash. The volcanic ash shows there were two volcanic irruption's, but they weren't…

Stone Descriptions: Marble Marble is a metamorphosized sedimentary rock. Due to different crystallizations and impurities present over the millennia, marble comes in an infinite variety of color. For this reason, and given its preciousness, marble is generally used in construction for interior and exterior purposes. For similar reasons, we generally see this material in the form of slabs, and not as a structural building material. Marble is a relatively porous stone. This makes it easily…

Three minerals that are common are feldspars which can be pinkish grey in colour, quartz which can be grey or white in colour, and It also contains small specs of mafic minerals which are dark. It contains crystals, which are interlocking. Mirco granite are pinkish in colour, but can also be grey at times. Ercall Granophyre is a unconformably overlain by Lower Cambrian sandstones. Micro granite forms in an area with magma and quartz rock. The crystals are smaller than granite, which means that…

SETTING AT OUTCROP The rocks of the Wilberns Formation have a very involved history. Today, the Wilberns outcrops are found in the Llano uplift region of central Texas, the most prolific Wilberns outcrops are to the west of the Llano uplift area (Bell and Barnes, 1972, p. 28). The Llano uplift area is a geologically complex region of central Texas (fig. 3). Precambrian metamorphic and plutonic igneous rocks mostly dominate the Llano region. The uplift brought Cambrian Wilberns rocks to the…

Recognized as being one of the richest sedimentary basins in petroleum and gas for its comparatively small size, the Los Angeles Basin is a Neogene age sedimentary basin whose complex formation history makes it a unique marvel of the western continental margin (Ward, 1994). In order to understand the importance that the discovery of oil has had in the Los Angeles Basin, we look to the events that have taken place in the basin itself that created the conditions necessary for the formation of oil.…

The chemists' main objection focused on two isotopes of the element neodymium. By measuring the relative abundances of the isotopes in a rock, geochemists can tell whether the rock originated in the mantle lithosphere -- the slice of the North American jelly sandwich that, according to Bird, the Farallon Plate had dragged away. When the chemists checked the neodymium, however, the rocks proclaimed that the mantle lithosphere is very much intact. The evidence was compelling; many of Bird's…

Missouri’s Geology Missouri is home to a wide variety of geological history as well as treasure which can be found throughout the state. From its wonderful variety of caves to the rock columns in the state parks of the south as well as the mines. The soil is as rich in diversity as the plant and animal life, from the north to the south as well as the east to the west. It can be dated back as far as before there was life on this planet and at one time even had an ocean over it. It is truly…

Mine at the south and the mine site runs roughly parallel to Ely Brook. Bedrock Geology Three bedrock formations underlie the Orange County copper district: the Waits River Formation, Standing Pond Volcanics, and the Gile Mountain Formation. Figure 4 outlines the boundaries of these formations. The Waits River Formation consists of metamorphosed carbonate and siliciclastic turbidites formed during the Early to Middle Silurian age. These deposits are the oldest, as determined by the law of…

and has an excelent stability. It is an adaptable, versatile material. it can be shaped into the desired form, it is easy to cut and manipulate. It can be reheated and melted to drastically reshape. PET is in fact a recyclable material. According to author Chris Letheri on his book Materials for Design, PET represents one of the biggest areas of recycling. It is labled as the number 1 in the recycling symbol. 3Form, Varia Ecoresin contains 40% pre-consumer recycled content. PET is a…
