Rock Classification Experiment
The laboratory experiment was about to sort the given amount of rocks into
different categories based on their colors and textures including white rocks which
referred to quartz, pink rocks which referred to feldspar, and shiny black or gray rocks
which referred to mica. Other than that, the rocks were also categorized on whether the
rocks are all other pieces which referred to hornblende or dull black pieces which referred
to basalt and so on. After that, we had to answer the questions based on the specimen’s
attribute that include the color, the cluster, the cleavage, and the hardness level of the
rocks. The experiment was interesting because of the importance of classifying rocks, as
rocks are characterized to make it less difficult on geologists to have them identified later
on (Wilson, 1995). Moreover, if these rocks were studied and compared to each other,
there could be some great insights as rocks were the clues to the past as they could tell us
about the past in greater details including the past temperature or the past atmosphere
thickness, especially when things such as fossils were on the rocks (Gilluly, 1959). Our
findings throughout the experiment included that about 40% of the rocks were all other
pieces (hornblende), less than 1% of the rocks were dull black pieces (basalts and so on),
about 25% of the rocks were all white (quartz), about 10% of the rocks were all pink
(feldspar), and about 25% of the rocks were shiny gray or black (mica).
The issue that could be raised during the laboratory experiment was sometimes it
was hard to distinguish the color of the rocks correctly in order to put them into the
appropriate classification. This issue was significant because if the color of the rocks had



been detected wrongly, they would have been put into the wrong classification, which
would in advance have yielded the incorrect ...
