Thematic collections are curated sets of papers that present a timely snapshot of research in a topic of high current interest and importance.
Edited by experts in the field, invited contributions undergo peer review to the normal JGS standards and are made available online upon acceptance. The papers are collated on a dedicated collection webpage on an ongoing basis which ensures that this significant research is visible to the community at the earliest opportunity.
If you are interested in proposing a thematic collection in JGS then please contact jgs@geolsoc.org.uk. Please provide a brief proposal for the Editorial Board to consider that outlines the aims and scope of the thematic collection, the guest editors and the envisaged contributions.
Current thematic collections:

Advances in the Cambrian Explosion: Evo-Devo, Paleobiology, and Geobiology This thematic issue aims to present the works addressed and discussed during the International Conference on the Cambrian Explosion (ICCE) which was organized at Chengjiang, Yunnan, China, during 9-15, November 2019. Articles in this collection cover a range of recent advances in the aspects of evo-devo, paleobiology and geobiology on the Cambrian Explosion of animals.
Future thematic collections:

Isotopic dating of deformation We warmly welcome studies that characterize deformation in detail from micro- to macroscopic scale prior to isotopic dating. We would like to discuss innovation, suitability and limitation of the applied method particularly dating deformation rather than metamorphism. We are interested in discussing the significance of the analytical versus systematic errors in the light of technical improvements enabling analyses of tiny (high spatial resolution) but distinctly different (microtexture) targets with high precision geochronology.
Read the completed thematic collections:

The Geology of Fractured Reservoirs The papers gathered in this thematic collection explore the many ways in which the geology of fractures is fundamental to the understanding of fluid flow in the subsurface, and hence to the prediction of reservoir performance.
Polygenetic mélanges: a glimpse on tectonic, sedimentary and diapiric recycling in convergent margins The papers gathered in this thematic collection explore with different methodologies (from field-structural and stratigraphic observations to geophysical analyses) different types of polygenetic mélange, at various scales, around the world.

Carbon forms: paths and processes in the Earth This collection of lecture notes focusses on the structure of carbon allotropes, the geodynamics of deep Earth's carbon transport and fixation at mantle conditions, carbon degassing by ascending magmas, and the vast tectonic carbon degassing at the Earth’s surface.
The Mid-Carnian Episode This thematic set originates from discussions at the first meeting on the Carnian Pluvial Episode (CPE) at Hanse-Wissenschaftskolleg, Institute for Advanced Study in 2017.

The Apennines Tyrrhenian System This thematic collection collates papers presenting results from latest research on the evolution and structure of the Apennines that was presented in the thematic session “TS 7.13 / GD 8.7 / GMPV 9.2 / SSP 2.16 - The Apennines-Tyrrhenian system: Multidisciplinary contributions to the understanding of the tectonic setting, magmatism and geodynamic evolution” at EGU2018 meeting.

Tethyan ophiolites and Tethyan seaways The papers in this thematic set demonstrate the differences in the Neotethyan ophiolite record through new structural, geochemical, isotopic and geochronological data and interpretations.
JGS Review Focus series:

The Lagerstätten collection Fossil Konservat-Lagerstätten are sites of exceptional fossil preservation that serve as our key archives of evolutionary history.
