Presented below are the research topics that Ph. However, the emergence and early evolution of two fundamental characteristics of divergent plate boundaries, segmentation and magmatism, are not well understood because most studies focus on mature or successfully rifted margins. Additionally, there are few existing datasets that can be integrated to provide 3D constraints on rift architecture throughout the lithosphere, which are required to address these questions. This investigation produced estimates of mantle temperature and melt content within the rift and also highlighted the potential location of melt segregation along a steeply dipping lithosphere-asthenosphere boundary.

List page numbers of all figures. The list should include a short title for each figure but not the whole caption. List of Tables List page numbers of all tables.

The list should include a short title for each table but not the whole caption. Introduction You can't write a good introduction until you know what the body of the paper says.

Consider writing the introductory section s after you have completed the rest of the paper, rather than before. Be sure to include a hook at the beginning of the introduction. You should draw the reader in and make them want to read the rest of the paper.

The next paragraphs in the introduction should cite previous research in this area. It should cite those who had the idea or ideas first, and should also cite those who have done the most recent and relevant work. You should then go on to explain why more work was necessary your work, of course.

What else belongs in the introductory section s of your paper? A statement of the goal of the paper: Do not repeat the abstract. Sufficient background information to allow the reader to understand the context and significance of the question you are trying to address.

Survey Sampling Methods

Proper acknowledgement of the previous work on which you are building. Sufficient references such that a reader could, by going to the library, achieve a sophisticated understanding of the context and significance of the question. The introduction should be focused on the thesis question s.

All cited work should be directly relevent to the goals of the thesis. This is not a place to summarize everything you have ever read on a subject.

Explain the scope of your work, what will and will not be included. A verbal "road map" or verbal "table of contents" guiding the reader to what lies ahead. Is it obvious where introductory material "old stuff" ends and your contribution "new stuff" begins?

Remember that this is not a review paper.

Break up the introduction section into logical segments by using subheads. Methods What belongs in the "methods" section of a scientific paper? Information to allow the reader to assess the believability of your results.

Information needed by another researcher to replicate your experiment. Description of your materials, procedure, theory. Calculations, technique, procedure, equipment, and calibration plots.

Limitations, assumptions, and range of validity. Desciption of your analystical methods, including reference to any specialized statistical software. The methods section should answering the following questions and caveats: Could one accurately replicate the study for example, all of the optional and adjustable parameters on any sensors or instruments that were used to acquire the data?

Could another researcher accurately find and reoccupy the sampling stations or track lines? Is there enough information provided about any instruments used so that a functionally equivalent instrument could be used to repeat the experiment?

If the data are in the public domain, could another researcher lay his or her hands on the identical data set? Could one replicate any laboratory analyses that were used?
