Mineral resource models and the Alaskan Mineral Resource Assessment Program Mineral resource models and the Alaskan Mineral Resource Assessment Program
The least exacting demand that can be made of any model is that it serves as a device whereby we can predict actual physical happenings. Another demand which could be made is that the physical happenings predicted be in some way relevant to man, either by allowing him to anticipate future uncontrollable events or by demonstrating the possible consequences of various decisions. To date...

Peritidal lithologies of Cambrian carbonate islands, Carrara Formation, southern Great Basin Peritidal lithologies of Cambrian carbonate islands, Carrara Formation, southern Great Basin
The Carrara Formation is a heterogeneous sequence of quartzites, siltstones, shales, limestones, dolostones, and mixed terrigenous-carbonate rocks. It is Early and Middle Cambrian in age (Stewart, 1970; Palmer, 1971).

Some effects of pollutants in terrestrial ecosystems Some effects of pollutants in terrestrial ecosystems
Summary: Pollutants tend to simplify plant and animal communities by causing a progressive loss of species. At the extreme, this leads to erosion and loss of soil fertility. Weedy, broadly adapted species increase. Among animals, carnivorous species and groups are often the first to suffer. This is partly because of their exposure at the top of the food chain, and partly, it appears...
