Fine-grained interplanetary dust input during the Turonian (Late Cretaceous): evidence from osmium isotope and platinum group elements [PDF]

open access: yesScientific Reports, 2023
The Turonian age (~ 90–94 Ma) was the hottest geological interval in the Cretaceous and also marked by the K3 event, a pronounced enrichment of 3He in pelagic sediments (i.e., massive input of extraterrestrial materials).

Microvertebrate faunal assemblages of the Favel Formation (late Cenomanian-middle Turonian) of Manitoba, Canada [PDF]

open access: yesPeerJ, 2023
Microvertebrate assemblages of the Upper Cretaceous (late Cenomanian to mid-Turonian) Favel Formation of Manitoba are formally described for the first time. New vertebrate occurrences from the Favel Formation include the actinopterygians Caturidae indet.,

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Volcanogenic Turonian and epiclastics of senonian in the Timok magmatic complex between Bor and the Tupižnica mountain, eastern Serbia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2005
In the light of the findings presented in this paper, among the volcanic products of the Upper Cretaceous, referred to as "the first volcanic phase" (Drovenik, 1961), two lithostratigraphic units can be singled out within the Timok Magmatic Complex (TMC):

The Cenomanian/Turonian boundary in light of new developments in terrestrial palynology [PDF]

open access: yesScientific Reports, 2023
The Cenomanian/Turonian boundary interval is associated with an oceanic anoxic event (OAE 2,  94.0 Ma) during one of the warmest episodes in the Mesozoic.

The Cenomanian-Turonian transition on the Peruvian margin [PDF]

open access: yesCretaceous Research, 1993
Abstract In Peru, various deposittonal sequences can be recognized during the late middle Cenomanian to early Coniacian timespan, most of which seem to have an eustatic origin. For instance, the early late Cenomanian, late early Turonian and early Coniacian maximum floodings identified in Peru coincide with well-known global eustatic events.

Biostratigraphy of Turonian to (?)Coniacian Platform Carbonates: A Case Study from the Island of Cres (Northern Adriatic, Croatia) [PDF]

open access: yesGeologia Croatica, 2003
The shallow marine carbonate deposits on the island of Cres, overlyingdeeper-water Cenomanian–Turonian limestones, are characterizedby an assemblage of rudists, benthic foraminifera, and associatedmicrofossils.

PETROPHYSICAL CHARACTERIZATION BY 3D MODEL OF ZONES 4 AND 3 OF THE TURONIAN RESERVOIR OF THE KINKASI FIELD IN THE D.R. CONGO COASTAL BASIN [PDF]

open access: yesRomanian Journal of Petroleum & Gas Technology, 2023
Kinkasi is one of the oil fields of the DR Congo Coastal Basin. It is essentially formed of two main geological units (A and B) in the Turonian, each composed of a succession of different horizons (Zones) according to the type of siltstone.
