Abstract
The report deals with the thermal effects of sedimentation, when the sedimentary basin is considered an integral part of the lithosphere. The deposition of cold sediments, called thermal blanketing, is studied. A general one-dimensional temperature equation is obtained which accounts for blanketing, the movement of the lower boundary of the lithosphere, and the eventual stretching of the lithosphere. This equation is made dimensionless, and then studied in two different settings; one where the lithosphere remains unstretched, and another where the lithosphere is subjected to constant strain rate stretching. The parameter controlling thermal blanketing in these models is a Peclet number. The transient period towards a stationary state, and the stationary state representing maximal blanketing are studied. General conclusions about the possibilities for blanketing are stated in terms of the Peclet number. 12 refs., 12 figs., 3 tabs.
