Name:
In this quiz you will be asked to identify, on your own, three rock samples. For each rock
identify whether
the
rock is igneous, sedimentary, or metamorphic
. Then,
list relevant features for the rock sample
depending on
the rock type as you did for samples during prior labs that help identify the rock (grain size, sorting, minerals,
fabrics, etc.). Based on these features,
provide your identification
.
IF, the rock is sedimentary mention a
probable depositional environment. IF the rock is metamorphic posit a probable protolith. IF the rock is
igneous posit whether the rock was formed in an intrusive or extrusive setting.
