Dear all,

     Yardley  in the book "An Introduction to Metamorphic Petrology" pag. 126 writes.........
....it becomes convenient for the description of  metamorphosed calcareous  sediments
to divide them into two categories: marbles in which carbonates are abundant; and calc-silicates
with little or no carbonate.
Can anyone suggest me  if  a rock made up of calcite ( 30%) , and   wollastonite+diopside+
grossular+ quartz  (70%)  can be classified as calc-silicate?
      Thanks in advance,
                  Marcello Franceschelli
