Overview

Top Research Topics at New Zealand Journal of Geology and Geophysics?

The primary areas of discussion in New Zealand Journal of Geology and Geophysics are Paleontology, Geochemistry, Geomorphology, Seismology and Oceanography. Cretaceous, Sedimentary rock, Group (stratigraphy), Pleistocene and Quaternary are all topics related to Paleontology research discussed. The majority of Sedimentary rock studies are focused on the issues of Clastic rock.

The Geochemistry study tackled is a key component of adjacent topics in the area of Mineralogy. The journal is mostly focused on Geomorphology, specifically Glacial period. Fault (geology) and Tectonics are Seismology topics of special interest in the journal.

Presentations on Volcano include those discussing Rhyolite and Andesite. New Zealand Journal of Geology and Geophysics investigates Volcanic rock research which frequently intersects with Basalt. The journal features Metamorphic rock research that overlaps with concepts in Metamorphism.

  • Paleontology (34.32%)
  • Geochemistry (27.71%)
  • Geomorphology (15.95%)

What are the most cited papers published in the journal?

Research areas of the most cited articles at New Zealand Journal of Geology and Geophysics:

The most cited papers aim to foster the development of research in Geochemistry, Paleontology, Geomorphology, Seismology and Volcano. The featured Geomorphology studies in the published articles mainly concentrate on Quaternary but also cover areas of interest in Radiocarbon dating and Oceanography. While Volcano is the focus of the published articles, it also provides insights into the studies of Volcanism and Basalt.

The previous edition focused in particular on these issues:

The journal investigates areas of study like Geochemistry, Paleontology, Volcano, Seismology and Volcanism. Pyroclastic rock is a primary topic of Geochemistry research in the journal. As a part of New Zealand Journal of Geology and Geophysics, discussions in Paleontology involve topics like Cenozoic, Holocene, Neogene, Gondwana and Subduction.

The Volcano works featured in the journal incorporate elements from Radar, Geothermal gradient and Earth science. Volcanism research presented in New Zealand Journal of Geology and Geophysics encompasses a variety of subjects, including Paleoclimatology, Thermoluminescence dating, Intraplate earthquake, Tephrochronology and Basalt. While work presented in it provided substantial information on Fault (geology), it also covered topics in Schist, Structural geology and Excavation.

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, 4.76% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 88.33% were posted by at least one author from the top 10 institutions publishing in the journal. Another 0.00% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 8.33% of all publications and 3.33% 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.
