SiO2-FeOt/MgO diagram (Miyashiro 1974)

Description

Assigns data for SiO2 vs. FeOt/MgO diagram into Figaro template (list 'sheet') and appropriate values into 'x.data' and 'y.data'

Usage

Miyashiro()

Details

Diagram in SiO2 vs. FeOt/MgO space, proposed by Miyashiro (1974), defines the following fields:

Tholeiite Series
Calc-alkaline Series

As the boundary was defined by Akiho Miyashiro as straight line passing through two specific points, no limits of diagram validity for ultrabasic and high-silica rocks were given. Thus, the boundary implemented in GCDkit script spreads from FeOt/MgO=0 to SiO2=100 %.

Value

sheet

list with Figaro Style Sheet data

x.data

SiO2 weight percent

y.data

FeOt/MgO weight percent
