Journal of the Geological Society of Japan

Top Research Topics at Journal of the Geological Society of Japan?

The topics of Geochemistry, Paleontology, Seismology, Geomorphology and Group (stratigraphy) are the focal point of discussions in the journal. The studies on Geochemistry discussed can also contribute to research in the domains of Mineralogy and Petrology. Many of the studies tackled connect Paleontology with a similar field of study like Peninsula.

Research areas of the most cited articles at Journal of the Geological Society of Japan:

The main points discussed in the journal articles deal with Geochemistry, Paleontology, Seismology, Geomorphology and Cretaceous. While Geochemistry is the focus of the journal publications, it also provides insights into the studies of Tectonics, Mineralogy and Petrology. Paleontology studies presented in the most cited papers include Permian, Group (stratigraphy), Biostratigraphy, Neogene and Pleistocene.

What topics the last edition of the journal is best known for?

• Paleontology
• Ecology
• World War II

The previous edition focused in particular on these issues:

Journal of the Geological Society of Japan mostly deals with topics like Geochemistry, Paleontology, Cretaceous, Metamorphic rock and Trough (geology). Most of the Geochemistry studies addressed also intersect with Shear zone. Cretaceous research featured in the journal incorporates concerns from various other topics such as Clastic rock, Dike, Position (vector), Andesite and Granitic rock.

It explores topics in Metamorphic rock which can be helpful for research in disciplines like Permian and Igneous rock. Topics in Trough (geology) explored in the journal were investigated in conjunction with research in Neotectonics, Geomorphological analysis and Submarine canyon. In addition to Tectonics research, the journal aims to explore topics under Fauna and Structural basin, Viséan, Carboniferous.

The most cited articles from the last journal are:

• The U-Pb zircon dates from the Maeshima Granodiorite in Amakusa City, Kumamoto Prefecture, Southwest Japan (1 citations)
• Progress in tsunami sedimentology (1 citations)
• Geologic structures and basin formation tectonics in and around Toyama Trough, the Sea of Japan (1 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 7.69% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 54.17% were posted by at least one author from the top 10 institutions publishing in the journal. Another 25.00% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 20.83% of all publications and 0.00% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
