    2005-3-1  Minerals in the Earth's Crust. There are more than 3000 known minerals (the number is still growing), but of these only about 20 are very common, and only 9 of these constitute 95% of the crust.These 9 minerals are all silicates, and are also called the rock forming minerals.They can be subdivided into two groups, the mafic and felsic minerals

  • ROCKS AND ROCK- FORMING PROCESSES

    COMPETING VIEWS OF ROCK-FORMING PROCESSES (3) The debate between the Neptunist and Vulcanist views was ultimately resolved by observations and additional studies performed by many geologists. French geologists, in particular, were among the first to recognize that volcanoes played a greater role in rock formation than permitted by the Neptunist ...
