what to deliver ?

• a single, digital, feldspar ternary diagram in either Excel or Sheets – the corners will be Ab, An, and Or
• a self-designed, self-explanatory calculator where feldspar values can be entered into the appropriate cells and ALL the necessary calculations will be done automatically and the data will be plotted as a single point on the ternary diagram. I recommend using colors, boxes, and written instructions to help explain to the user (me) where to enter the data correctly.
• plot the following feldspar compositions on the diagram, AND then using your notes and textbook, tell what type of feldspar each one is :
• An = 5, Ab = 85, Or = 10
• An = 66, Ab = 30, Or = 4
• An = 32, Ab = 67, Or = 1
• An = 2, Ab = 2, Or = 96
• An = 87, Ab = 10, Or = 3
