A triple junction in the Gulf of Mexico: Implications for deep petroleum exploration [PDF]

Geofísica Internacional, 2004
Mesozoic redbed and salt sequences have recently been dated using a palynostratigraphical method developed at the Mexican Petroleum Institute (IMP) since 1975. They represent the early Mesozoic marine transgression which formed the petroleum systems. The

Major Δ14C excursions during the late glacial and early Holocene: changes in ocean ventilation or solar forcing of climate change? [PDF]

, 2003
The atmospheric 14C record during the Late Glacial and the early Holocene shows sharp increases simultaneous with cold climatic phases. These increases in the atmospheric 14C content are usually explained as the effect of reduced oceanic CO2 ventilation ...

Initiation of the Ferrar Large Igneous Province Started in Southern North Victoria Land, Antarctica, With Shallow Emplacement of Sills Causing Magma‐Soft‐Rock Interaction and Phreatomagmatic Eruptions

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Early Jurassic volcanism was in the southern north Victoria Land portion of the Ferrar Large Igneous Province preceded by multiple phases of shallow‐level intrusions of Ferrar sills into the 300 m thick cover of sedimentary rocks of the Triassic‐Jurassic Victoria Group.

PALYNOSTRATIGRAPHY OF THE MUFARA FORMATION (MIDDLE-UPPER TRIASSIC, SICILY)

Rivista Italiana di Paleontologia e Stratigrafia, 2002
The study of 10 sections of the Mufara Formation in northern Sicily yielded four palynomorph associations ranging in age from late Ladinian/early Carnian to late Carnian, and identified a trend in the compositional evolution of the assemblages within the

Preliminary Palynostratigraphic Age Assessment of Victoria and Ferrar Group Deposits in the Central Prince Albert Mountains, Victoria Land, East Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Composition and age span of sedimentary deposits of the Transantarctic Basin system vary between different regions of the Transantarctic Mountains. Moreover, whereas the regional stratigraphic successions have been very well established in some areas of East Antarctica, such as the Allan Hills or the Beardmore Glacier, they remain virtually unexplored ...
