I have just read about diorite in the section on rocks of a book about minerals, rocks and fossils, Mineral, Rocks and Fossils by A.C. Bishop, A.R. Woolley, W.R. Hamilton.

Did you know? Xenoliths are common in diorite.

I have just read about andesite in Mineral, Rocks and Fossils by A.C. Bishop, A.R. Woolley, W.R. Hamilton.

Did you know? Andesite is formed as lava flows but may also form dykes.

I have just read about andesite in the glossary at the end of Chapter 2, “Earth and its resources”, under the section THE PHYSICAL UNIVERSE in volume 1, THE WORLD OF NATURE, of the Reader’s Digest Library of Modern Knowledge.

Did you know? The predominant mineral in andesite is plagioclase feldspar; biotite, hornblende and augite may also occur.

I have just read about andesite line in The Concise Oxford Dictionary of Geography.

Did you know? In the Pacific there is a line marking the boundary between the basic rocks of the oceanic crust and the acid rocks of the continental crust: it is the boundary between oceanic sima and continental sial.

I have just read about andesite in The New Penguin Dictionary of Geology.

Did you know? Andesite is commonly porphyritic with phenocrysts of zoned sodic plagioclase, biotite, hornblende and pyroxene in a groundmass of the same minerals and more sodic plagioclase and quartz.

Did you know? Andesite grades into latite with increasing alkali feldspar and into dacite with increasing alkali feldspar and quartz.
