The Earth’s Upper Mantle.

Одномерная референтная модель Земли




Introduction

This article contains general information about the Earth’s upper mantle. This article discusses the methods for studying the internal structure of the upper mantle of the Earth. The author gives arguments in favor of the fact that the study of the internal structure of the upper mantle of Earth is an extremely important and urgent task. For more information about the Earth’s upper mantle can be found on the website http://www.virtualuppermantle.info.

Earth’s upper mantle

Earth’s upper mantle is a layer with a capacity of up to 600 kilometers, which lies between the Earth’s crust and lower mantle of Earth. The upper boundary that separates the upper mantle of the Earth’s crust – it is a Mohorovichich boundary (Moho). Moho boundary is located at a depth of 5 to 70 kilometers from the Earth’s surface. The lower boundary that separates the upper and lower mantle – it is a transition zone. The is located in the depth interval 400 – 650 kilometers from the Earth’s surface.

Physical and chemical processes

Physical and chemical processes taking place in the Upper mantle of the Earth, have a great and often decisive influence in many geodynamic, geophysical, geochemical phenomena observed at the Earth’s surface. In the past two decades, global plate tectonics (Mobilism) has been widely accepted in the scientific community. And it could be argued that this theory is the paradigm of our time. From the standpoint of Mobilism explains many geodynamic, geological, geophysical, geochemical phenomena issues earthquake prediction, the distribution of mineral resources. But the cornerstone of Plate tectonics – the reason the movement of the plates. And a source of energy for the movement of the plates, and the substrate on which the plates “float” on the modern, are located in the upper mantle of the Earth. Therefore, the study of the Upper mantle – it is a very urgent task.

Seismology, Gravimetry, Geothermal, Geomagnetism.

The direct penetration to great depths inside the Earth – a difficult task. The level of complexity of the task can be represented graphically, if we compare the achievements in space surrounding the Earth and in the development of the depths of the Earth itself. In the space mission next year are manned flights to Mars and Venus. In the development of Terrestrial depths of humanity to overcome the first ten kilometers. And the upper mantle of the earth lies much deeper. Therefore, a major supplier of information about the Earth’s upper mantle are the geophysical methods of research such as Seismology, Gravimetry, Geothermal, Geomagnetism. Information provided by geophysical methods, is indirect. That is, it can not be taken in hand, as a model species, and the knock on him a hammer. The data of all geophysical methods should be studied in conjunction. The geophysical data have to compare, with petrological, mineralogical, geochemical and other geological data. Only with such an integrated approach to the study of the Upper mantle of the Earth can produce reliable results.

Structural seismology

The central place among the geophysical methods of exploration of the Upper mantle of the Earth occupies a Structural seismology. One of the main reasons that the seismic data developed for well-established technologies for the extraction of information about the internal structure of the upper mantle of the Earth from the observed seismic data. These technologies can be grouped under the title “Seismic tomography”.

Я отношусь к той категории советских людей, которых называют "Ташкентскими русскими". Это эндемики, сохранившие в окружении инородной культуры своеобразную русскую, еще дореволюционную культуру, и прежде всего, язык. А так же впитавших в себя много хорошего из окружавшей нас по жизни восточной культуры. Еще нас называют "Совками". Но это относится не только к бывшим жителям гостеприимного Ташкента, но к жителям всего Советского Союза, сформировавшимся, как личности, во времена Советского Союза. Многих из нас судьба разбросала по всему Земному шару. Нам не хватает привычного общения. Наши дети и внуки, помимо своей воли, становятся "иностранцами". Блог – это то место, где я смогу выговориться, а если повезет, то и поговорить с людьми моего поколения. Спасибо Интернету, он предоставляет нам такую возможность.

  1. Write more, thats all I have to say. Literally, it seems as though you relied on the video to make your point. You obviously know what youre talking about, why waste your intelligence on just posting videos to your blog when you could be giving us something informative to read?

  2. Hey! I know this is somewhat off topic but I was wondering which blog platform are you using for this website? I’m getting sick and tired of WordPress because I’ve had issues with hackers and I’m looking at options for another platform. I would be great if you could point me in the direction of a good platform.

  3. Does your site have a contact page? I’m having trouble locating it but, I’d like to shoot you an email. I’ve got some ideas for your blog you might be interested in hearing. Either way, great site and I look forward to seeing it improve over time.

  4. Hmm is anyone else experiencing problems with the images on this blog loading? I’m trying to find out if its a problem on my end or if it’s the blog. Any feed-back would be greatly appreciated.
