Megascopic Classification of Rocks
Year: 1991
Type: article
Abstract: A new classification of rocks that requires almost no tools other than a hand lens and that is both comprehensive and informative is described in this paper. These classifications should be useful in many classroom, laboratory, and field situations where the alternative classifications are either overly simplistic in that they provide little useful information or overly analytical in that they require optical and/or chemical data that are not readily available. The rock classifications presented here are our megascopic adaptations of the more popular analytical classifications in use today. Each of the three main rock groups is treated in two-dimensional, rectangular charts with additional appended boxes that provide optional mineralogical and textural terms that can be used with the rock names.
