New Perspective

Building on Fielding’s idea of escalator regions as places where young people migrate (often temporarily) to get rapid career advancement, this paper proposes a new perspective on 'escalator migration' as it applies to frontier or remote regions in particular. Life events, their timing and iterations have changed in the thirty years since Fielding first coined the term ‘escalator region’, with delayed adulthood, multiple career working lives, population ageing and different dynamics between men and women in the work and family sphere. The object of this paper is to examine recent migration trends to Australia's Northern Territory for evidence of new or emerging 'escalator migrants'.

Two Bodies

Within the Western slope of the Southern Urals, there are plenty of basite dyke complexes of Riphean to Vendian among Precambrian terrigenous-carbonate formations. In metamorphic formations of the Taratash complex (Archean to Early Proterozoic, the northern closure of the Bashkirian meganticlinorium) there was observed the andesitic dyke with isotopic age of 71±1 Ma (U-Pb SHRIMP II on zircons) and near Bakal two bodies of gabbroids with zircons of similar ages were found. These are the first evidence of possible Mezozoic magmatism in this region.
