Texture	Non-foliated	Foliated	Foliated	Non-foliated
Identify

2. Below are descriptions of characteristics of six different common rocks. Use the descriptions and your E.S.R.T. to identify the six different rocks.

Sample #1

Black, low density, no visible crystals, shows evidence of fossil plants

Sample #2

Light-colored, low density, visible crystals, coarse texture, contains quartz and feldspar

Sample #3

Black, shiny, low density, no visible crystals, glassy texture

Sample #4

Distorted structure, no visible crystals, high density, shows color bands

Sample #5

Mixed colors, low density, pebbles imbedded in a sandy base, cemented

Sample #6

Colorless, no visible crystals, low density, cleaves into tiny cubes
