PHYSICAL ASPECTS OF THE CONTRACTION HYPOTHESIS OF OROGENESIS
Keyword(s):
Several geophysical arguments important in the theoretical consideration of the contraction hypothesis of orogenesis are analyzed in detail with respect to their physical bases. Specifically, it is shown (a) that a thin surface layer of a sphere will fold in a smaller pattern than a thicker surface layer if the interior shrinks by the same amount; (b) that the speed of cooling of a sphere decreases if some radioactive and hence heat generating material is moved from the surface towards the center (and conversely); and (c) that at the level of no strain of a cooling sphere the temperature–depth curve must be almost straight. Those geological theories in which these considerations are important are indicated.
