Sediment‐stressed reefs over the past 420 Myr
The Depositional Record, EarlyView.In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

An overview of lithotype associations of Miocene lignite seams exploited in Poland
Geologos, 2016 Currently, three stratigraphically distinct lignite seams of Early to Middle Miocene age are exploited in Poland, namely the third Ścinawa lignite seam (ŚLS-3), the second Lusatian lignite seam (LLS-2) and the first Mid-Polish lignite seam (MPLS-1).

Petrochemical Characteristics of Cenozoic Basalts in Datong, Shanxi
Taiyuan Ligong Daxue xuebao, 2021 Basalt in the Cenozoic period in Datong, Shanxi can be divided into two types: alkaline basalt in the northwest and tholeiite basalt in the southeast. Petrological and geochemical analyses were carried out on the basalts in Datong area. As known from the

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: a synthesis and review [PDF]
, 1996 The stable oxygen isotope composition (d¹⁸O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (d¹³C) reflects the source of CO2 for ...

Carbonate sedimentology: An evolved discipline
The Depositional Record, EarlyView.Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]
, 2008 Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

The Depositional Record, EarlyView.The lacustrine Gördes Supradetachment Basin was developed along the Simav detachment fault during postorogenic extension in the north of the Menderes Massif in western Anatolia. The basin‐fill succession is represented by alluvial fan, Gilbert‐type delta, shoal‐water delta, foreshore, shoreface, offshore‐transition and peat‐forming mire deposits.

The case for dynamic subsidence of the U.S. east coast since the Eocene [PDF]
, 2008 The dynamic subsidence of the United States east coast is addressed using the discrepancy between regional and global estimates of sea level, elevation of paleoshorelines, and adjoint models of mantle convection that assimilate plate motions and seismic ...

The Depositional Record, EarlyView.The deep paleo‐lake, characterised by low energy and moderate salinity, facilitated the input of fine‐grained minerals and the development of aquatic organic matter. Under the combined influence of the sedimentary environment and material source, mineral‐bound organic matter was formed, which played a crucial role in the enrichment of organic matter ...

The age and origin of the central Scotia Sea [PDF]
, 2010 Opening of the Drake Passage gateway between the Pacific and Atlantic oceans has been linked in various ways to Cenozoic climate changes. From the oceanic floor of Drake Passage, the largest of the remaining uncertainties in understanding this opening is
