Marine transgression in the context of "Onlap"

The 7th millennium BC spanned the years 7000 BC to 6001 BC (c. 9 ka to c. 8 ka). It is impossible to precisely date events around this millennium, and all dates mentioned here are estimates mostly based on geological and anthropological analysis.

Towards the end of this millennium, the islands of Great Britain, and Ireland were severed from continental Europe by rising sea levels.

The Campanian is the fifth of six ages of the Late Cretaceous epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.2 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian.

The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks.

The Mississippian (/ˌmɪsɪˈsɪpi.ən/ MISS-iss-IP-ee-ən), also known as Lower Carboniferous or Early Carboniferous, is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.86 to 323.4 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley.

The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas.

Nusantara, officially Nusantara Capital City (Indonesian: Ibu Kota Nusantara, abbreviated IKN), is a city under construction that, upon completion, is planned to be the capital city of Indonesia. It occupies land in the East Kalimantan regencies of Kutai Kartanegara and Penajam North Paser on the east coast of the island of Borneo. Nusantara is planned to be a capital specific region at the provincial level with the official complete name Nusantara Capital Specific Region Province or Province of the Capital Specific Region of Nusantara (Indonesian: Provinsi Daerah Khusus Ibu Kota Nusantara), replacing Jakarta to save the city from overpopulation and land sinking. Nusantara is adjacent to the port city of Balikpapan, which serves as the main gateway to the new capital.

After being postponed due to the COVID-19 pandemic, construction of the city began in 2022, starting with land clearing and creating access roads. The project is estimated to be worth Rp 523 trillion (US$35 billion) and will be built in five phases lasting until 2045, to coincide with the 100th anniversary of Indonesia. Phase 1, known as the "Main Governmental Area" zone, started in August 2022. Around 150,000 to 200,000 workers from around Indonesia participated in this project with an additional workforce around the Nusantara region to ensure the participation of local workers.

The Red Crag Formation is a geological formation in England, deposited from the latest Pliocene to the earliest Pleistocene (Gelasian). It outcrops in south-eastern Suffolk and north-eastern Essex. The name derives from its iron-stained reddish colour and crag which is an East Anglian word for shells. It is part of the Crag Group, a series of notably marine strata which belong to a period when Britain was connected to continental Europe by the Weald–Artois Anticline, and the area in which the Crag Group was deposited was a tidally dominated marine bay. This bay would have been subjected to enlargement and contraction brought about by transgressions and regressions driven by the 40,000-year Milankovitch cycles.

The sediment in the outcrops mainly consists of coarse-grained and shelly sands that were deposited in sand waves (megaripples) that migrated parallel to the shore in a south-westward direction. The most common fossils are bivalves and gastropods that were often worn by the abrasive environment. The most extensive exposure is found at Bawdsey Cliff, which is designated a Site of Special Scientific Interest (SSSI); here a width of around 2 kilometres (1.2 miles) of Crag is exposed. At the coastline by Walton-on-the-Naze, remains of megalodon were found.

Nusantara, officially Nusantara Capital City (Indonesian: Ibu Kota Nusantara, abbreviated IKN), is a city under construction that, upon completion, is planned to be the capital city of Indonesia. It occupies land in the East Kalimantan regencies of Kutai Kartanegara and Penajam North Paser on the east coast of the island of Borneo. Nusantara is planned to be its own national capital region (Indonesian: daerah khusus ibu kota negara) at the provincial level, replacing Jakarta to save the city from overpopulation and land sinking. Nusantara is adjacent to the port city of Balikpapan, which serves as the main gateway to the new capital.

After being postponed due to the COVID-19 pandemic, construction of the city began in 2022, starting with land clearing and creating access roads.
