Mesoproterozoic Era and lasted from 1200 Mya to 1000 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically. The name derives from narrow polymetamorphic belts formed over this period. Preceded by the Ectasian Period and followed by the Neoproterozoic Era.- Neoproterozoic (Wikipedia)
The Neoproterozoic Era is the unit of geologic time from 1 billion to 538.8 million years ago. It is the last era of the Precambrian Supereon and the Proterozoic Eon; it is subdivided into the Tonian, Cryogenian, and Ediacaran periods. It is preceded by the Mesoproterozoic Era and succeeded by the Paleozoic Era of the Phanerozoic Eon.
- Tonian (Wikipedia)
The Tonian (from Ancient Greek: τόνος, romanized: tónos, meaning “stretch”) is the first geologic period of the Neoproterozoic Era. It lasted from 1000 to 720 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry. The Tonian is preceded by the Stenian Period of the Mesoproterozoic Era and followed by the Cryogenian.
- Gang war in Haiti (Wikipedia)
Since 2020, Haiti’s capital, Port-au-Prince, has been the site of an ongoing gang war between two major criminal groups and their allies: the Revolutionary Forces of the G9 Family and Allies (FRG9 or G9) and the G-Pep. The Government of Haiti and Haitian security forces have struggled to maintain their control of Port-au-Prince amid this conflict, with gangs reportedly controlling up to 90% of the city by 2023.
- Mesoproterozoic (Wikipedia)
The Mesoproterozoic Era is a geologic era that occurred from 1,600 to 1,000 million years ago. The Mesoproterozoic was the first era of Earth’s history for which a fairly definitive geological record survives. Continents existed during the preceding era (the Paleoproterozoic), but little is known about them. The continental masses of the Mesoproterozoic were more or less the same ones that exist today, although their arrangement on the Earth’s surface was different.
- Ectasian (Wikipedia)
The Ectasian Period (from Ancient Greek: ἔκτασις, romanized: éktasis, meaning “extension”) is the second geologic period in the Mesoproterozoic Era and lasted from 1400 Mya ago to 1200 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.
