Sedimentology and palaeoenvironmental analysis of a karstic shallow carbonate lake (Early‐Middle Miocene, Sinj Basin, Croatia)

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 121-146, February 2025.
Miocene karstic Lake Sinj. A prograding carbonate bench on a gently inclined lake margin showing shallowing upwards tendency, and closing of the lake. Abstract In the Early to Middle Miocene, the post‐orogenic intramontane lacustrine Sinj Basin that belonged to the Dinarides Lake System evolved in the area of the External Dinarides.

Quaternary Lives

open access: yesGeologija, 2007
After a short-lived »ban«, the Quaternary has again been formalized as a chronostratigraphic unit, consisting of the Pleistocene and the Holocene.

Role of tidal range and coastline morphology on the evolution of two macrotidal sand spits

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 311-327, February 2025.
Based on historical map and stratigraphic data, the construction dynamics of two sandspits, respectively, subject to macrotidal and hypertidal range (6.5 m vs. 14 m), and that both appeared at the end of the 17th century, are compared. The hypertidal spit developed fast, between 1650 and 1750 CE, with a dominant seaward direction while the macrotidal ...

THE GELASIAN STAGE: A PROPOSAL OF A NEW CHRONOSTRATIGRAPHIC UNIT OF THE PLIOCENE SERIES

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
A new Stage, the Gelasian, is proposed as the third upper subdivision of the Pliocene Series. The GSSP of the base of the Gelasian Stage and of the Middle Pliocene-Upper Pliocene boundary is coincident with a "sapropel" level which outcrops in the Monte ...

The Anthropocene concept as a wake-up call for reforming democracy [PDF]

open access: yes, 2018
Human activity has reshaped all parts of the Earth system. For this reason, a vast majority of geologists at the 35th International Geological Congress in Cape Town (September 2016) spoke out in favor of changing the classification of geological epochs ...

Cretaceous cyclic peritidal carbonates of the Apulia Carbonate Platform (Apulia, southern Italy) in a hierarchical sequence‐stratigraphic perspective: A case study from the Murge area (the Giovinazzo sea‐cliff section)

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 328-353, February 2025.
Four different types of elementary sequences (condensed, catch‐down, catch‐up and give‐up) were recognised and interpreted in terms of relative sea‐level changes to reconstruct the relative sea‐level curve of the entire succession. The envelope of the reconstructed relative sea‐level curve was used to represent the long‐term accommodation change on the

High resolution carbon isotope stratigraphy of the basal Silurian stratotype (Dob's Linn, Scotland) and its global correlation [PDF]

open access: yes, 1997
Since its designation as the Global Stratotype Section and Point (GSSP) for the base of the Silurian System, the choice of Dob's Linn, Southern Scotland, has received criticism due to the difficulties of relating its well constrained graptolite ...

Punctuated aggradation and flow criticality in deep water channel systems

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 354-372, February 2025.
Sinuous deepwater channels may form meander belts or aggrading systems, and may alternate between the two states repeatedly. We invoke two‐layer subcritical flow to explain their river‐like behaviour, and suggest that a switch from subcritical to supercritical flow may be responsible for the change in behaviour from meandering to aggrading.

Ammonites and stratigraphy of a Lower Bajocian (Middle Jurassic) section in Sierra Chacaico (Neuquén Basin, Argentina) [PDF]

open access: yes, 2012
A Lower Bajocian section from southern Neuquén Basin (Argentina), with 3 faunal horizons (sphaeroceroides, submicrostoma and giebeli horizons) in the Singularis and Giebeli zones, is described.
