The Tourmaline Group has a general formula of AX3Y6(BO3)3 Si6O18(O, OH, F)4.  The A can be either calcium or sodium.  The X can be either aluminum, iron, lithium or magnesium.  The Y is usually aluminum, but can also be chromium or iron.  Some potassium can be in the A position, some manganese can be in the X position and some vanadium can be found in the Y position, but these elements are usually not represented in the formulas of the tourmaline members.
