Rock, Mineral, and Parent
Material Identification Lab
(14pts.)
Identify the 28 rocks, minerals, or
unconsolidated parent materials in Dow 290. Numbers in parentheses
indicate how many specimens are present. Questions after each rock
type only have to be answered once. For example, there are five different
sandstones that need to be identified. The question, "What sort of
soil texture is typically associated with this rock?" only needs
to be answered once, on any appropriate line on the lab data
sheet. To assist you with this lab, there will be
two rock and mineral identification texts in the lab along with this
on-line guide to rock identification.
| quartzite (2) What was this rock before it was metamorphosed? |
limestone (3) What effect would the weathering of this rock have upon
soil pH? |
gneiss (2) |
sandstone (5) What sort of soil texture is typically associated
with this rock? |
| granite (2), Name three common minerals associated with this rock. |
schist (2) |
till (1), How is this deposit distinguished from fluvioglacial deposits? |
conglomerate (2), In what type of environment would a conglomerate form?
What would you guess the bulk density to be of a soil weathered from
conglomerate? |
| basalt (2), What type of volcanic eruption is associated with this rock? |
fulgurite, (1) how does this deposit form? |
loess, (1) This well sorted deposit is associated with what type of
environment? |
shale, (2) Once weathered into a soil, what type of permeability and
porosity will result? |
| alluvium (1) This well sorted deposit is associated with what type of
environment? |
lead (Pb), (1) What dangers do does the weathering of this mineral pose to
children? |
coal, (1) How do future wetlands contribute to coal foramtion? |
