These variations provide insight into global carbon cycle dynamics, as well as relative age information (chronostratigraphy) that can be used to correlate sedimentary successions globally. The global carbon cycle includes both short- and long-term components, and their interactions dominate the isotopic record presented in this chapter. The partitioning and sequestration of carbon between organic and carbonate rock reservoirs, and their fluxes to and from the ocean–atmosphere–biosphere system, drive secular changes in the δ13C of DIC in the oceans that are ultimately recovered from the stratigraphic record. The pre-Cenozoic data presented here utilize bulk carbonate data for compilation, but a wide range of materials has been analyzed in the literature to produce previous composites. Care must be taken to consider what materials have been analyzed in comparing global carbon isotope records from the literature.","source":"Semantic Scholar","year":2020,"language":"en","subjects":["Environmental Science"],"doi":"10.1016/b978-0-12-824360-2.00011-5","url":"https://www.semanticscholar.org/paper/4bc60c89877fc37866e1daf93f5a4a1d1ce7be70","is_open_access":true,"citations":269,"published_at":"","score":72.07},{"id":"doaj_10.3389/feart.2026.1742001","title":"Mechanism and failure model of group-occurring loess falls induced by domestic sewage discharge: insight from field investigation and flume experiment","authors":[{"name":"Baofeng Wan"},{"name":"Baofeng Wan"},{"name":"Boren Tan"},{"name":"Dehao Xiu"},{"name":"Hang Yang"},{"name":"Maoyuan Chen"},{"name":"Ning An"},{"name":"Ning An"},{"name":"Ruidong Li"},{"name":"Ruidong Li"},{"name":"Dalei Peng"}],"abstract":"Group-occurring loess falls are common catastrophic geological hazards on the Loess Plateau, typically triggered by heavy rainfall, excessive irrigation, or earthquakes. However, group-occurring loess falls induced by sustained sewage discharge are exceedingly rare. To better understand the failure mechanism of group-occurring loess falls caused by persistent domestic sewage scouring in Liudian Village, Qingyang City, Gansu Province, multi-temporal remote-sensing images and UAV-derived DEMs, together with field investigations, were used to track slope evolution. ERT and drilling were used to characterize subsurface moisture and stratigraphy. A flume test was set up using analogous materials, and water infiltrated from the constant-level tank at the slope toe. Displacement and inclination were monitored. The results show that basal loess saturation increased progressively and caused collapsible settlement. Once the basal layer became fully saturated, the slope toe gradually softened, and capillary action promoted the upward migration of moisture, saturating the upper slope. This hydrological process induced plastic deformation and slow creep, eventually resulting in an overall slope fall and sliding. The entire failure process can be divided into three stages: steady-state deformation, accelerated deformation, and final failure, each displaying distinct characteristics. These observations indicate an erosion-controlled, time-dependent cumulative failure pattern with recurrent collapses under sustained toe water supply. In the future, mitigation can focus on sewage diversion and toe flow interception, together with localized toe protection, to reduce long-term scouring and infiltration.","source":"DOAJ","year":2026,"language":"","subjects":["Science"],"doi":"10.3389/feart.2026.1742001","url":"https://www.frontiersin.org/articles/10.3389/feart.2026.1742001/full","is_open_access":true,"published_at":"","score":70},{"id":"crossref_10.1016/b978-0-443-26536-5.00007-x","title":"Sequence stratigraphy","authors":[{"name":"Octavian Catuneanu"}],"abstract":"","source":"CrossRef","year":2026,"language":"en","subjects":null,"doi":"10.1016/b978-0-443-26536-5.00007-x","url":"https://doi.org/10.1016/b978-0-443-26536-5.00007-x","is_open_access":true,"published_at":"","score":70},{"id":"crossref_10.3390/stratsediment1010001","title":"Stratigraphy and Sedimentology—A New Open Access Journal","authors":[{"name":"Brian K.

Catuneanu"}],"abstract":"Abstract Stratal stacking patterns provide the basis for the definition of all units and surfaces of sequence stratigraphy. The same types of stacking patterns may be observed at different scales, in relation to stratigraphic cycles of different magnitudes. At each scale of observation, stacking patterns define systems tracts, and changes in stacking pattern mark the position of sequence stratigraphic surfaces. The construction of a framework of systems tracts and bounding surfaces fulfills the practical purpose of sequence stratigraphy. Beyond this framework, model-dependent choices with respect to the selection of the ‘sequence boundary’ may be made as a function of the mappability of the various types of sequence stratigraphic surface within the studied section. Sequence stratigraphic frameworks are basin-specific in terms of timing and scales of the component units and bounding surfaces, reflecting the interplay of global and local controls on accommodation and sedimentation. A stratigraphic sequence corresponds to a cycle of change in stratal stacking patterns, defined by the recurrence of the same type of sequence stratigraphic surface in the rock record. Sequences, as well as component systems tracts and depositional systems, can be observed at all stratigraphic scales. Sequences of any scale may include unconformities of equal and/or lower hierarchical ranks, whose identification depends on the resolution of the data available. The relative ranking of sequences of different scales is defined by their stratigraphic relationships, as lower rank sequences are nested within higher rank systems tracts. Despite this nested architecture, the stratigraphic framework is not truly fractal because sequences of different scales may differ in terms of underlying controls and internal composition of systems tracts. A scale-independent approach to methodology and nomenclature is key to the standard application of sequence stratigraphy across the entire range of geological settings, stratigraphic scales, and types of data available.","source":"Semantic Scholar","year":2019,"language":"en","subjects":["Geology"],"doi":"10.1016/J.EARSCIREV.2018.09.017","url":"https://www.semanticscholar.org/paper/c39060c68999790e9e78ffbe90c8538c7438c5a4","is_open_access":true,"citations":214,"published_at":"","score":69.42},{"id":"ss_c4baf251d006f8e1f4453253bebab6cb5b833c32","title":"Permian integrative stratigraphy and timescale of China","authors":[{"name":"S.

Here, we develop a set of corrections for systematic error and determine uncertainties to be used in the calculation of the above parameters for zircon, using the same methodology as Zeigler et al. (2023) for apatite.

For both zircon and apatite, the Geometric Correction Method is a practical and straightforward approach for calculating more accurate (U–Th) \u003cspan class=\"inline-formula\"\u003e\u003cmath xmlns=\"http://www.w3.org/1998/Math/MathML\" id=\"M25\" display=\"inline\" overflow=\"scroll\" dspmath=\"mathml\"\u003e\u003cmo\u003e/\u003c/mo\u003e\u003c/math\u003e\u003cspan\u003e\u003csvg:svg xmlns:svg=\"http://www.w3.org/2000/svg\" width=\"8pt\" height=\"14pt\" class=\"svg-formula\" dspmath=\"mathimg\" md5hash=\"64e3733ac81609367f37ca130d7132b9\"\u003e\u003csvg:image xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"gchron-6-199-2024-ie00006.svg\" width=\"8pt\" height=\"14pt\" src=\"gchron-6-199-2024-ie00006.png\"/\u003e\u003c/svg:svg\u003e\u003c/span\u003e\u003c/span\u003e He data and for including geometric uncertainty in eU and date uncertainties.\u003c/p\u003e","source":"DOAJ","year":2024,"language":"","subjects":["Geology","Stratigraphy"],"doi":"10.5194/gchron-6-199-2024","url":"https://gchron.copernicus.org/articles/6/199/2024/gchron-6-199-2024.pdf","is_open_access":true,"published_at":"","score":68},{"id":"ss_a7b635ec8ac22a4e39308096a551a0ed9a2e629f","title":"Stratigraphy","authors":[{"name":"J.

The species composition of the fauna is associated with the Albian-Cenomanian (for a single gravelly interlayer of Kholodniy Yar taphocoenoses) and the Cenomanian (two fossiliferous gravelly interlayers at Melanchin Potik). Along with elasmobranchs, fos- siliferous gravel sands contain remains obviously redeposited from the more ancient strata. The probability and scope of redeposition decrease from the Kholodnyi Yar taphocoenosis, through the Melanchin Potik lower layer, to the Melanchin Potik upper layer. The stratigraphic intervals are assumed to be wider for Kholodnyi Yar (the Albian-Cenomanian) and narrower for Melanchin Potik (the Cenomanian). The fossiliferous gravelly interlayers resulted from transgressive-regressive events. With the transgressing sea eroding the previously formed deposits containing fauna and flora remains, the latter were redeposited, sorted and waterworn due to the tidal zone hydrodynamics. The condi-tions described account for mixed taphcaenoses (those of the Melanchin Potik lower layer and Kholodnyi Yar). Besides, a more powerful rewashing may have affected a previously gravelly interlayer, which is likely for Kholodnyi Yar. The transgressive events seem to have been rather dynamic: deep-water deposits containing no fossils rapidly replaced the litoral and sublitoral ones. The following regressive-transgressive cycle therefore resulted in the formation of unmixed taphocoenoses in the basal horizon. In general, the Cenomanian palaeolandscapes of the study area were more even than the Albian ones. The Albian islands were characterized by a great variety of mesophite flora and physiographic conditions. On the contrary, low flattened shores of the Cenomanian islands did not favour the development of tree vegetation.","source":"Semantic Scholar","year":2020,"language":"en","subjects":null,"doi":"10.2307/j.ctv170ww.4","url":"https://www.semanticscholar.org/paper/a7b635ec8ac22a4e39308096a551a0ed9a2e629f","pdf_url":"https://ieeexplore.ieee.org/ielx7/6962870/6970371/06970576.pdf","is_open_access":true,"citations":132,"published_at":"","score":67.96000000000001},{"id":"doaj_https://doi.org/10.30730/gtrz.2023.7.2.160-174","title":"Длинные волны на шельфе юго-западного побережья о.

Сахалин с использованием полученных в натурных экспериментах временных серий колебаний уровня моря с дискретностью 1 с и продолжительностью от 4 до 6 мес. Спектральный анализ временных серий колебаний уровня моря для диапазона периодов от 8 до 200 ч выявил наличие длинноволновых процессов с периодами от 26.1 до 46.7 ч, которые значительно превышают инерционный период 16.48 ч. Численное моделирование шельфовых волн для экспоненциально выпуклых профилей морского дна, проведенное с использованием дисперсионного соотношения В.Т. Бухвальда и Дж.К. Адамса для волн континентального шельфа, показало, что обнаруженные волновые процессы с периодами от 31.2 ч до 46.7 ч являются шельфовыми волнами. Их амплитуды увеличиваются во время штормов; показана возможность передачи энергии от атмосферных возмущений шельфовым волнам, которые вносят вклад в формирование уровня моря, что подтверждает ранее сделанное предположение. Путем расчета разности фаз шельфовых волн на расстоянии 12.4 км между Невельском и Горнозаводском, наблюдаемых и определенных по теоретической модели, установлено, что вторая мода шельфовой волны с частотой 0.152 цикл/ч близка к теоретической. Регистрируемая в Ильинском и Горнозаводске волна с периодом 26.1 ч при расстоянии между пунктами 173.6 км не может быть шельфовой, а является волной Кельвина. Это подтверждено рассчитанной дисперсионной диаграммой, согласно которой длина волны около 689 км хорошо соответствует разности фаз для расстояния Ильинский–Горнозаводск. Установлено, что шельфовые волны, одним из механизмов генерации которых является напряжение ветра вдоль берега, имеют разные амплитуды в летнее и зимнее время, что обусловлено сезонным направлением вдольберегового ветра. В летний период направления распространения шельфовых волн и ветра противоположны, что ослабляет шельфовые волны.\r\n","source":"DOAJ","year":2023,"language":"","subjects":["Dynamic and structural geology","Stratigraphy","Engineering geology.
