As we all know, publishing academic papers is a scholar's daily "job" and a symbol of academic influence and status in his peers.I just completed one of the eight lectures (4 academic hours) in the School's 2022 and 2023 equivalent Ph.D. Program, in which I quote former editor-in-chief of Science, D. Emphasizing the significance of academic papers, Dr Kennedy said: "All of our thinking, analysis, experimentation and data collection work is nothing before we write the paper.In the academic world, our results are expressed in terms of what is written, and publications, like hard currency, are the basic manifestations of academic achievement (from the web)."We will summarize some of the findings of scientific research and publish them publicly for scientific colleagues to share the results of scientific research is the source of scientific workers' happy scientific research work life.This paper does not talk about the experience of publication of the paper, but only a little experience of the discovery process of "flashpoint" of the results of the paper, for young scholars to refer to.In order to make everyone understand the production process of academic papers, I will talk about the "innovative elements" and "scientific problems" from scientific research materials.Although the scientific properties of "earth science" are different from those of other disciplines, I think the basic connotation and ideas of academic research are in common.The "excellence" here is obviously my own perception and the reaction after the publication of the paper combined with expert review opinions, rather than simply based on the "grade" of the published paper journal.
All four papers belong to "deep geophysical directions" in the field of geoscience.This paper is mainly from the 973 project of the Ministry of Science and Technology: mantle dynamics and modern crustal action of continental plate convergence boundary (led by academician Xu Zhichin).There is also the National Natural Science Foundation project "Research on Multi-Phase Change Rock Magnetic Response in the Continental crust-mantle Region in Eastern China" and "Research on the Relationship between Crustal Rock Physical Properties and Geological Processes".In carrying out Project 973, I was privileged to receive a core sample of the China Continental Scientific Drilling-CCSD, an extremely valuable national effort.The magnetic results of the core samples produced three papers published in the Journal of Geophysical Research-Solid Earth (JGR) and one in the Journal of Structural Geology (JSG).The following is a brief description of the thesis element analysis process.
JGR's first paper: 171 out of 335 samples in CCSD are metamorphic eclogite samples, which are ideal targets for studying the high-pressure-ultra-high-pressure eclogite refraction process in Sulu region.To this end, geologists (including tectonic geology, petrology, mineralogy and geochemistry, etc.) have conducted extensive research and published a number of high-level academic papers.However, these papers did not address the study of the physical properties of rocks.The results of rock minerals and geochemistry in core samples provide an excellent opportunity to use rock physical parameters to independently visualize deep geodynamic processes.Therefore, 171 samples with different degrees of degeneration were used to analyze the variation characteristics of rock magnetism and reveal the control of rock magnetism by the folding process of high-pressure metamorphic eclogite in Sulu region.In this paper, the relationship between rock magnetic variation and fresh eclogite, partial metamorphic eclogite and complete metamorphic eclogite (up to keratite facies) is presented.The density and magnetic parameters of 171 samples should also be given in an appendix to the review expert's recommendations.Review experts believe that the study of degeneration is a good idea to control the magnetic characteristics of UHPG, and the results are very important for the interpretation of the magnetic characteristics of rocks in continental crust, especially in UHP metamorphic zone.

JGR second paper: 14 different levels of serpentine fossil garnet perovskite samples in the same core set of CCSD samples.This reminds me of the widespread serpentine petrochemical process in the continental crust-upper mantle and the work of renowned rock mineralogist Professor Zheng Jianping in mantle lithology.The samples involved "revealing the interrelationship between the folding process of eclogite and serpentine petrification of pomegranate perovskites using the magnetic variability characteristics of the rocks," which is the "scientific question" embodied in the paper.The authors agree that it is an important scientific goal to study the relationship between high magnetism and ultra-high pressure metamorphism in ultra-high pressure metamorphism zone.

JGR's third paper: Robinson et al., Cambridge University, UK, published in Nature in 2002, proposed the original idea that the thin layer (Lamellar) structure of hematite-titanite series minerals would produce strong residual magnetization strength.This view is of great scientific significance to the basic theory of rock magnetism, as well as to the study of the structure of regional magnetic anomalies.Three of the 171 eclogite samples in the core of CCSD showed significant exfoliated lamellar structures.They are a good example of testing the theory of control of residual magnetization by thin-layer structures proposed by Robinson et al.Therefore, the magnetic parameters, mineral composition and thin-layer structure of the three samples were measured by systematic analysis, and the relationship between the magnetic properties and thin-layer structure was obtained.The high magnetic properties of these thin-layer eclogites may be related to the magnetic field sources of highland magnetic anomalies in the Sulu subduction zone.

Fourth (JSG) paper: The characteristic heavy magnetic anomaly(the metamorphic zone coincides with the heavy magnetic anomaly zone) was distributed in the Sulu-UHP metamorphic zone.
