Overview

Top Research Topics at Episodes?

The journal primarily tackles Paleontology, Geochemistry, Earth science, China and Archaeology. It concentrated on Paleontology research, specifically Stage (stratigraphy), Global Boundary Stratotype Section and Point, Stratotype, Tectonics and Series (stratigraphy).

  • Paleontology (20.88%)
  • Geochemistry (12.83%)
  • Earth science (7.61%)

What are the most cited papers published in the journal?

  • The ICS International Chronostratigraphic Chart (1492 citations)
  • Sources and settings of granitic rocks (1048 citations)
  • Petrogenesis of Mesozoic granitoids and volcanic rocks in south China : a response to tectonic evolution. (1006 citations)

Research areas of the most cited articles at Episodes:

The journal articles generally zeroe in on subjects such as Paleontology, Global Boundary Stratotype Section and Point, Stage (stratigraphy), Geochemistry and Stratotype. The journal papers connects the study in Paleontology with the closely related areas of Base (topology). Issues in Geochemistry were discussed in the published articles, taking into consideration concepts from other disciplines like Magmatism and Craton.

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

  • World War II
  • Law
  • Paleontology

The previous edition focused in particular on these issues:

The concepts of Geochemistry, Paleontology, Archaeology, Stage (stratigraphy) and Global Boundary Stratotype Section and Point are tackled in Episodes. The concepts on Geochemistry presented in it can also apply to other research fields, including Mechanism (sociology), Redox, Carbonate and Pluton. Episodes links adjacent topics like Paleontology with Base (topology).

Episodes facilitates discussions on Base (topology) that incorporate concepts from other fields like Czech, Point (geometry), Stratotype and Ordovician. Topics in Archaeology explored in it were investigated in conjunction with research in Value (mathematics), Petrography, Gneiss and Function (engineering). It explores topics in Quaternary which can be helpful for research in disciplines like Paleomagnetism, Ratification, Tephra and Series (stratigraphy).

The most cited articles from the last journal are:

  • Formal ratification of the Global Boundary Stratotype Section and Point (GSSP) for the Chibanian Stage and Middle Pleistocene Subseries of the Quaternary System: the Chiba Section, Japan† (5 citations)
  • Proposal for the Global Boundary Stratotype Section and Point (GSSP) for the Priabonian Stage (Eocene) at the Alano section (Italy) (4 citations)
  • Natural Stones: architectonic heritage and its global relevance (2 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.

The top authors publishing in Episodes (based on the number of publications) are:

  • Dolores Pereira (13 papers) published 3 papers at the last edition, 1 more than at the previous edition,
  • Alberto Carlos Riccardi (10 papers) absent at the last edition,
  • Umberto G. Cordani (10 papers) absent at the last edition,
  • Martin J. Head (10 papers) published 2 papers at the last edition, 1 more than at the previous edition,
  • Igcp Secretariat (10 papers) absent at the last edition.

The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.

Only papers with recognized affiliations are considered

The top affiliations publishing in Episodes (based on the number of publications) are:

  • Chinese Academy of Sciences (30 papers) published 3 papers at the last edition, 1 more than at the previous edition,
  • University of Delhi (20 papers) published 2 papers at the last edition, 7 less than at the previous edition,
  • Wadia Institute of Himalayan Geology (14 papers) absent at the last edition,
  • Russian Academy of Sciences (13 papers) absent at the last edition,
  • University of Salamanca (13 papers) published 5 papers at the last edition, 3 more than at the previous edition.

The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.

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, 10.17% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 33.96% were posted by at least one author from the top 10 institutions publishing in the journal. Another 5.66% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 24.53% of all publications and 35.85% 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.
