Prize quarry

dogfish and a total allowable catch of zero for 2010. Scientists had recommended a zero catch for this year as studies suggest the northeast Atlantic population is on the verge of collapse. Catches for cod outside the North Sea, hake, monkfish, sole and whiting have also been agreed at levels higher than those recommended by EU advisors. The Bay of Biscay anchovy fishery is to remain closed but...

PROPERTIES OF FLOWABLE SELF-COMPACTING SLURRY USING QUARRY BY-PRODUCTS AND PONDED CCPs

This paper reports the properties of two series of flowable self-compacting slurry (SCS). In Series 1, a limestone quarry by-product, fine crushed sand (FCS), and ponded-CCPs were used. For Series 2, standard concrete sand and ponded-CCPs were used. For Series 1, five mixtures and for Series 2, six mixtures of flowable SCS were made. Ponded-CCPs and limestone quarry FCS content of the mixtures ...

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...

Marine Geology

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...
