Scheme for Igneous Rock Identification … For … 1.Which sedimentary rock would be formed by the compaction and cementation of particles 1.5 centimeters in diameter? (1) land-derived sedimentary rock Ohemically formed sedimentary rock (3) nonfoliated metamorphic rock For phaneritic rocks, the percentage must add up to 100%!!! finally the name of the rock as determined from the sedimentary rock identification chart. A)chemical limestoneB)conglomerate C)granite D)sandstone 2.The diagram below shows actual sizes and shapes of particles removed from a clastic sedimentary rock. For phaneritic rocks, you will identify the minerals and estimate the percentage of each mineral in the rock. When you classify objects, you organize them into groups based … o Overall rock composition: Use one of the following terms: felsic, intermediate, mafic o Rock name: Use the appropriate name from the classification scheme … In most cases, the symbol shows something about the texture of the rock.

In the first three sessions, you will familiarize yourselves with the characteristics of – and learn to describe, identify and interpret – the three main Set 2 — Scheme for Sedimentary Rock Identification 10. The sediments are from A)shallow … Use the Scheme for Sedimentary Rock Identification to answer the following questions. The right side of the Scheme for Sedimentary Rock Identification shows symbols often used to represent various sedimentary rocks on diagrams and maps. (l) shale fossil limestone (2) siltstone (4) breccia 10 11. Be sure to fill out all of the features possible before naming the rock, even though a number of the rocks will be immediately obvious … Which sedimentary rock may form as a result of biologic processes?
