Indian Geology

Geology of the Maggie Property , Indian River Area , Southwestern British Columbia

The property consists of 84 units in I I claims, staked in 1976 by H. Hopkins after finding copper-lead-zinc mineralization (Clendenan and Pentland, 1979). Since 1977, work by International Maggie Mines Ltd. and Placer Developrnent Limited (now Placer Dome Inc.) has included mapping, trenching, 78 drill holes tot:alling 8005 metres, and two short adits with drifts followinf; mineralization (Dru...

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...

The Journal of Geology

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...

The Geology of Vesta

The Dawn spacecraft collected over 28,000 images and a wealth of spectral data of Vesta’s surface. These data enable analysis of Vesta’s diverse geology including impact craters of all sizes and unusual shapes, a variety of ejecta blankets, large troughs, impact basins, enigmatic dark material, and considerable evidence for mass wasting and surface alteration processes [1,2,3]. Two large impact...
