Metallogeny and the New Global Tectonics

— The economic implications of the new global tectonics are reviewed according to plate anatomy. The uprises, stable platforms, downflows, and median zones exhibit particular features in ore genesis. Intercontinental metallogenic provinces, and intersection of transform fault trajectories with local structures as ore controls are discussed. Possible applications to Turkey are considered. HISTOR...

From Continental Drift to Plate Tectonics

SINCE THE l6TH CENTURY, CARTOGRAPHERS HAVE NOTICED THE jigsaw-puzzle fit of the continental edges. Since the 19th century, geologists have known that some fossil plants and animals are extraordinarily similar across the globe, and some sequences of rock formations in distant continents are also strikingly alike. At the turn of the 20th century, Austrian geologist Eduard Suess proposed the theor...

Plate Tectonics as a Far- From- Equilibrium Self-Organized System

Contained fluids heated from below spontaneously organize into convection cells when sufficiently far from conductive equilibrium. Fluids can also be organized by surface tension and other forces at the top. Plate tectonics was once regarded as passive motion of plates on top of mantle convection cells but it now appears that continents and plate tectonics organize the flow in the mantle. The f...

Looking at nurses' training from a counsellor's perspective.

'n Belangrike aspek wat dikwels met betrekking tot die huidige verpleegpersoneelkrisis verontagsaam word, is dat veral jonger verpleegkundiges aan besondere emosionele spanninge onderworpe is en dus persoonlike ondersteuning nodig het. Hierdie spanninge spruit voort uit faktore in die samelewing, die jong mens self, die verpleegberoep en dieonderrigsituasie. Emosionele ondersteuning van die stu...
