Whole Rock Chemical Analysis

Whole Rock Chemical Analysis

Whole Rock Chemical Analysis

(OP)
I am on project that requires a salt scaling test if the rock we are using more than 80% silious content.I carried out a whole rock chemical analysis which found that the rock had 65%SiO.Was I wrong in using this test.

RE: Whole Rock Chemical Analysis

Was the object to measure the wt. of the silicates, of the
S or of the equivalent SO2 ? The 65% SO2 may correspond to
significantly more silicate .

RE: Whole Rock Chemical Analysis

(OP)
The object was to determine if the aggregate was more than 80% siliceous or silicate rock type.The results of the test where SIO2 66.2%,AI2O3 15.6%,Fe2O3 4%,MgO 1.83%,Na2O 3.75%,K2O 2.28%, etc.

RE: Whole Rock Chemical Analysis

I repeat my question.
How do you define the "siliceous" or "silicate rock"?
There is some wt. difference between e.g. Mg or Ba
silicates.

The analysis had found Si in the amount equivalent to
65% SiO2.  You were asking if you were wrong to use
this test but you haven't preciselly define the object of the test.
