A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.
Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".
Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.
A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.
A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.
The 1994 Group was a coalition of smaller research-intensive universities in the United Kingdom, founded in 1994 to defend these universities' interests following the creation of the Russell Group by larger research-intensive universities earlier that year.
The 1994 Group originally represented seventeen universities, rising to nineteen, and then dropping to eleven. The Group started to falter in 2012, when a number of high performing members left to join the Russell Group. The 1994 Group ultimately dissolved in November 2013.
The group sought "to represent the views of its members on the current state and the future of higher education through discussions with the government, funding bodies, and other higher education interest groups" and "[made] its views known through its research publications and in the media".
Its oldest known settlements date back approximately 9,000 years. From the middle of the 4th century BC, the Kingdom of Macedon became the dominant power on the Balkan peninsula; since then Macedonia has had a diverse history.
Boundaries and definitions
The definition of Macedonia has changed several times throughout history.
Makedonia (Bulgarian:Македония, originally spelled Македонія) was a Bulgarian newspaper edited and published by Petko Slaveykov in Istanbul with aim to help the foundation of an independent Bulgarian Church. Started in 1866, Makedonia was one of the first Bulgarian newspapers and among the most popular at the time; it published news items, articles and discussion papers in the Bulgarian language and sometimes in the Greek language. It was stopped from printing in 1872 after the creation of the Bulgarian Exarchate.
Makedonia (Greek:Μακεδονία or Μακεδονικός Χορός) is a form of the Greek folk dance Hasapiko (Greek:χασάπικο) that has evolved over the years to the patriotic song "Makedonia Xakousti" (Famous Macedonia), unofficial anthem of the Greek region of Macedonia
