Field Trip Report: Great Valley Sequence and Coast Range Ophiolite The Moreno Formation in the Great Valley Sequence (GVS) is consisting of interbedded sandstones and organic-rich black shales, which were deposited during Upper Cretaceous (74-80 Ma) in near shore and shallow marine environment according to the fossils found. The sandstone in this outcrop is medium-sorted, angular to sub-angular arkosic arenite, with minerals such as quartz, plagioclase, muscovite and altered biotite. 1/4 of the muscovite was dated as 90 Ma old, matching the time of Cathedral Peak Intrusion. The provenance of the sandstone is probably granites. Round concretions on sandstones indicate calcite dissolution. The source of the sandstone can be peraluminous granite…

Trans-Pecos Province Magma Types Nathanial Matis 01/12/2014 Trans-Pecos Province Magma Types Nathanial Matis Abstract The Cretaceous was the starting point when the Laramide Orogeny began to fault and fold as a result of tectonic activity which pushed the Farallon plate into the North American plate forcing the subduction of the Farallon. This subduction caused the plate to melt and form magma that either formed laccoliths, or intruded country rock with different igneous compositions. These…

Granite is an igneous rock formed when large amounts of magma lowly solidify deep in the earth. The granite layer is not a straight edged layer like most in Vicunia, this represents the way magma has crept up into the landmass as opposed to being deposited, creating a nonconformity between the next layer. The next identifiable layer that lies directly on top, and partially in the middle of the granite, is a contact metamorphic rock layer. Contact metamorphic rock masses are formed with the aid…

New York exists on bedrock that tells a tale of millions of years ago, going as far back as the late Mesoproterozoic (1.6 to 1 billion years ago). The layers that make up this bedrock show the conditions of the earth’s surface through many different orogenies, which are times of high grade metamorphism and where plate tectonics makes its biggest changes. The Fordham gneiss was formed a billion years ago (oldest) during the Grenville orogeny (Precambrian) which featured sediment deposits and…

"The blue topaz has remained one of the most popular gemstones in the United States because of its vibrant blue color" (Branstrator). The blue topaz is the birthstone of those who were born in December. The blue topaz has also been a part of history, dating back to the Egyptians (Topaz History). The blue topaz is one of the most unique, fashionable, historical, and incredible gemstones on planet earth. The Blue topaz is found in the enormous crystals in pegmatite dikes (Topaz). Pegmatite dikes…

What effect do volcanos have on the Earth? This essay is going to be about volcanoes and how many are active. How many volcanoes have erupted and how long to they last? Many volcanoes are erupting as we speak and more than a thousand have erupted in the past 10,000 years. A volcanic eruption can last up to thousands of years. Scientists don’t have an accurate count of all the volcanoes, but there are about a thousand magma systems. What causes them to erupt and what effect do they have on the…
