GEOL 345 Lab 8: Fractional crystallization
1. Find the excel file “Kilauea_Iki_data_students.xls”
You will see that there are 4 sheets:
1. Surface samples
2. Drill core samples
3. Composite section
4. Data sources
We will be working only with the first two sheets!
Instructions and questions
The instructions will ask you to make several scatter plots in Excel. At the end of the
lab, copy and paste all of your plots into a Word or Powerpoint file. The graphs need to
be labeled or titled so I can tell whether they are surface or drill core samples. Include a
legend (at least on one plot) that distinguishes each sample type (whole rock, glass,
olivine). Axes on all graphs need to be properly labeled. Finally, adjust the axis scales to
minimize wasted space while still illustrating relevant data patterns—e.g., if your data
are all between 40-55% on one axis, it is silly for the axis to range from 0-100%.
This may seem like a bit of busywork, but making your graphs presentable and easy to
understand is essential to communicating your science. So, properly formatting your
plots as described here is worth a total of 5 points.
Type your responses in the space below each question.
1. Skim through sheet 1 and 2 (Surface samples and Drill core samples).
Familiarize yourself with the data. What types of samples have been analyzed in
each sheet? (Hint: whole rock and… ???) (1 point)
2. USING THE SURFACE WHOLE ROCK SAMPLES. Make scatter plots with
SiO2 on the x-axis, and MgO and FeOT on the y-axes. Was the lava that
erupted at Kilauea Iki in 1959 compositionally homogenous or heterogenous with
respect to MgO and FeOT? (4 points)
3. USING THE SURFACE WHOLE ROCK SAMPLES. Plot eruption dates on the
x-axis and oxides (e.g. SiO2, MgO, FeOT) on the y-axis. How did the
composition of the erupted lavas change during course of the eruption? Was this
change a continuous one, or does the change appear to be more complex? Did
the various element oxides steadily increase or decrease during the eruption? (2
points)
4. Assume the original magma coming from the deep mantle is
homogenous—it all has the same composition. Which process(es) do you
think may be responsible for the variance in the erupted lavas? Explain (2 points)
——————————————————————————————————————–Intermission:
Important pieces of information to consider at this point are the texture and
mineralogy of the erupted basalts. Most of these samples are porphyritic with
olivine phenocrysts in a finer-grained groundmass of clinopyroxene and
plagioclase, but also containing minor amounts of Fe-Ti oxides, apatite, and
orthopyroxene, and glass.
——————————————————————————————————————–The next few questions concern the possible origin(s) of the compositional variation in
the erupted lavas (i.e., the processes operating in the magma chamber(s) which
contributed magma to the eruption).
5. USING THE DRILL CORE SAMPLES. First make plots of SiO2 (x-axis) vs. MgO
and FeOT (y-axis) of just the whole-rock lava compositions. Describe the shape
of the geochemical trend defined by these samples—i.e., as SiO2 increases,
what do MgO and FeOT do? (3 points)
6. USING THE DRILL CORE SAMPLES. Add the olivine analyses to your plots
from the previous question. Why does the composition of the olivine vary?
(Hint: think about what was discussed in lecture about phase diagrams) (3
points)
7. USING THE DRILL CORE SAMPLES. Now add the glass analyses to the plots
from question 6. What do you think the glass represents: minerals or melts?
Explain (3 points)
*********
A Mg-rich olivine endmember, or forsterite, has the following composition:
40% SiO2, 0% FeOT and 60% MgO
While a Fe-rich olivine, or fayalite, has:
30% SiO2, 70% FeOT and 0% MgO
*********
In Excel, you can plot single data points by manually entering the X and Y values for the
data series (in the “Select Data” window) without highlighting data ranges in the
spreadsheet.
8. Add points for the forsterite and fayalite endmembers to your SiO 2 vs MgO and
FeOT plots, using the compositions given above. Make the points distinct (shape
and/or color) so I can tell them apart from the sample data.
a. Which process do you think produced the geochemical patterns you see in
the drill core data: fractionation of pure forsterite, fractionation of pure
fayalite, or fractionation of some intermediate olivine composition? Explain
your reasoning. (5 pts)
9. Most of this lab focuses on tracking how a melt evolves chemically as olivine
fractionates out of it. Another common mineral that we may expect to fractionate
from a basaltic melt relatively early is plagioclase.
a. In addition to SiO2, which two major oxides do you think will be most
affected by plagioclase fractionation? (2 pts)
b. Using the whole-rock and glass data for the drill core samples, plot these
two oxides on the y-axis and SiO2 on the x-axis of two separate plots. Is
there any indication of plagioclase fractionation in the data patterns? If so,
at approximately what SiO2 concentration does this start to occur? Explain
your reasoning. (2 pts)
Okay, now that you are done, make sure you send me everything:
1. This file, with your answers typed in.
2. Whichever file you pasted your nicely formatted plots into.
