Magma Contamination And Sulfide Immiscibility Of The Meteoric Impact Zone

Canada and especially Ontario have very interesting and much filled geologic pasts. Ontario has many types of rocks and minerals that have formed and are still forming due to the geology. Ontario has sedimentary rocks; igneous rock, and metamorphic rock as well as minerals such as gold, silver, quartz, and many more. In this paper, we will begin by talking about ten rocks that were collected right here in Windsor Ontario. The rocks were examined from the outside which tended to be weathered and the inside which were fresh.

Large amounts of iridium – a chemical element that is not a part of the Earth’s crust composition – were originally found in rocks of Europe and United States, and have been found everywhere ever since. Iridium, common in meteorites, is a testable evidence of the disaster hypothesis. Gould continues that the Cretaceous debacle, which is one of five episodes of mass dying, occurred at the same time as the large comet might have smashed into the Earth. The author believes this is not merely a coincidence, rather, it is a proof of the cause-effect relationship. The demise of a wide range of habitats along with the extinction of dinosaurs gives an inestimable advantage to the disaster theory over other claims, the author adds. The comet struck the Earth, and habitats, from terrestrial to marine, died with geological suddenness. Finally, this hypothesis has had an impact on the study of an atomic war and its consequences. A nuclear war, Gould says, may cause a huge drop in temperatures and result in the extinction of humanity. Testable evidence, study, development, contribution – all this makes good science.

Gerta Keller, professor of geosciences at Princeton University, has recently conducted research on the Chicxulub asteroid in which she analyzed new core samples taken from the asteroid site (Botzer 2004). These samples indicate that the impact that occurred at Chicxulub actually predated the mass extinction of the dinosaurs, which occurred at the Cretaceous-Tertiary boundary about sixty-five million years ago. Keller claims that the Chicxulub impact occurred approximately 300,000 years before the extinction (Keller 2004). Although previous researchers estimated that the Chicxulub asteroid was the cause of the extinctions, there had always been doubts about the exact age and size of the crater, and about the origin of the “mega tsunami deposits” that were located within the crater (Keller 2004). The focus of Keller’s recent research was on finding some answers to these questions. To do so she analyzed Cretaceous limestone, dolomite, and anhydrite deposits as the site of the Chicxulub crater (Keller 2004).

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

Copper-zinc (VMS-type?) mineralized zones were discovered in Archean volcanic rocks in the southern part of North Williams Township by Metron Explorations Limited in 1970. The mineralized zone and surrounding area were evaluated with a HLEM survey and drilled with 2 DDHs (totaling 61.3 m) that did not intercept significantly mineralized rocks (Willars, 1971).

Introduction - For the period of Sunday, August 28th – Sunday, September 4th, 2011, students from the University of Saskatchewan geological sciences department along with professors Dr. Kevin Ansdell and Dr. Kyle Larson took part in a geologic field school in and around the city of Flin Flon, Manitoba. The purpose of this field school was for students to

Sims et al. (1989) synthesized U-Pb zircon ages for the Pembine-Wausau terrane. Sims concluded that the volcanic rocks were generated from around 1889 to 1860 Ma as island arcs and closed back-arc basins above the south-dipping subduction zone (Niagara fault zone). Granitoid rocks in the terrane, emplaced from around 1870 to 1760 Ma, are mainly granodiorite and tonalite but include gabbro, diorite, and granite. These developed as island arcs above the Eau Pleine shear zone. The Niagara fault zone contains a relict ophiolite, suggesting that the rocks in the Pembine-Wausau terrane probably accumulated on

Impact craters are geologic structures formed when a large meteorite, asteroid or comet smashes in to a planet or a satellite. Meteorites are small rocks in space that hit the earth's atmosphere at a high velocity. Throughout their history they have heavily bombarded all the inner bodies in our solar system. In this experiment we will use marbles as our meteorites, these will be free falling objects that will be used to copy an asteroid impact. The surfaces of the Moon, Mars and Mercury, where other geologic processes stopped millions of years ago, record this bombardment clearly. On the Earth, however, which has been

The Iron Mask project occurs near the Sudbury Ni-Cu camp, which is part of the broader Abitibi granite-greenstone terrane

The sedimentary layers of rock and soil are used by the evolutionists to argue that the layers of rock would have gradually built up over millions of years. Paul D. Ackerman in his book, It’s a Young World After All: Exciting Evidences for Recent Creation, argues that if it took millions of years to build the rock layers found in the Grand Canyon, then scientists should be able to encounter countless numbers of meteors. “With the passage of vast amounts of evolutionary time, these accumulating meteorites would be incorporated into the geologic column, and there should be many of them contained in the rock layers today.” Geologists should be coming across chunks or at least pieces of meteors when digging or observing the layers. However, they do not; which means that there must have been a catastrophic event that laid down the geologic column quickly. This would explain why there are not any indications of meteors in the geological column. Ackerman ends the chapter with a clear cut conclusion: “What do the data show? A clear result in favor of a recent creation. One survey of the literature a few years ago failed to turn up a single case of a meteorite being found in the geologic column. The meteorite clock reads clearly to the effect that the earth is not very old.”

The Wabigoon Subprovince is part of the Superior Province, an Archean age craton composed of E-NE trending granite-greenstone and metasedimentary terranes that span from western MN to northern Quebec. In Canada, the Neoarchean Wabigoon subprovince hosts numerous precious and base metal deposits, including the Sturgeon Lake VMS deposits and Rainy River and Hammond Reef gold deposits (Figure 2). Historically considered moderately to weakly prospective for hosting VMS deposits due to inferred shallow marine conditions and relatively low temperature felsic volcanic rocks (Lesher et al., 1986; Gaboury and Pearson, 2008), the observation that many Wabigoon- hosted gold deposits may exhibit characteristics r of epithermal deposits

The Grand Canyon has plenty of volcanic rocks near the bottom and the top. ICR, Institute for Creative Research, has been involved in a project for years to date these volcanic rocks. this study has come a long way to show that many of the Grand Canyon strata could have formed rapidly, and that the erosion of the Canyon by the Colorado River has not been going on for millions of years.

Many believe that while Early Earth was undergoing accretion, it had a massive collision with a large body- as huge as the size of Mars (see Fig. 2.). This collision produced a shower of debris around the Earth and thrusted it into space (Grotzinger and Jordan, 2010). “According to this theory, the Earth reformed as a boy with an outer molten layer hundreds of kilometres thick- a magma ocean.” (Grotzinger and Jordan, 2010). Marshak (2007) deduced that the Moon was formed from the accretion of the debris floating around the Earth. He also suggested that the Moon’s composition resembles that of the mantle because of the way the Mars-sized body collided with the Earth. From this, we can assume that when the collision happened- it did not disturb the Earth’s iron-nickel core that was already formed. The formation of the Moon must have happened 4.51 billion years ago- between the early stages of the accretion of the Earth which was 4.56 billion years ago,) and “the formation of the oldest Moon rocks brought back by the Apollo astronauts (4.47 billion years ago,)” (Grotzinger and Jordan, 2010).

Earth rocks are very abundant in these minerals and other minerals that thrive in the high temperatures. They are almost completely deprived of these types of elements. Moon Rocks don?t. Moon Rocks also contain small ball like pieces of glass. The main theory on how this happened is by Moon dust being heated to extremely high temperatures along with other minerals. The hot dust would form a small glass piece, and the other minerals would form the rest of the rock. Earth rocks do not have this feature. .

Surprisingly, the clay held almost 30 times more iridium than the limestone layers above and below the clay. Similar layers in other parts of the world gave the same results. The conclusion was that a giant meteorite hit the Earth 65 million years ago and had released a large
