Experimental gallstones: an adventure in biological geology.
.... The Framingham Study was the first attempt to discover just how commonly gall bladder disease occurs . . . in the United States. That such a survey should not have been made before 1966 is sad evidence of an apathetic attitude toward the cause of gallstones.... At the age of fifty-five to sixtyfour, 10 per cent of men and 20 per cent of women have gallstones, or, in absolute terms, 2.5 to ...
متن کاملContribution to Experimental Geology : the Origin O F Esiiers .
A consideration of the theories involving the englacial formation of eskers, led to the construction of a simple apparatus with which esker systems could be reproduced. Esker-like forms were obtained by simulating a stream, heavily loaded with sediment, discharging into water ponded before a retreating ice front. T HE formation of eskars is a topic on which geologists are far from being in agre...

To constrain the timing of rifting in the western, eastern, and northern parts of the Alboran Sea basin, seismic reflectors, corresponding to biostratigraphic boundaries and unconformities from the Miocene to Recent, are correlated using synthetic seismograms. Regions of adjacent coeval compression and extension are found in the Alboran Sea basin. Normal faulting continues in parts of the easte...

As magmas rise toward the surface, they traverse regions of the mantle and crust with which they are not in equilibrium; to the extent that time and the intimacy of their physical contact permit, the melts and country rocks will interact chemically. We have modeled aspects of these chemical interactions in terms of ion-exchange processes similar to those operating in simple chromatographic colu...
