  Schorl - LoveToKnow Watches
It is commonly found that the schorl is of a brown colour in the interior of the crystals but blue at the edges; probably the brown is primary or has been derived from biotite, but the blue principally from the replacement of felspar.
The rock known as luxullianite, obtained near Luxullian village in Cornwall and used as an ornamental stone for the sarcophagus of the duke of Wellington's monument in St Paul's Cathedral, is a tourmaline granite in which the replacement of biotite and felspar by quartz and tourmaline can be seen in progress.
The new tourmaline is in fine pointed needles which have a stellate or divergent arrangement, and is embedded in quartz: often these needles are planted on the surface of corroded crystals of primary brown schorl.

Metasomatic tourmaline granites show every gradation from the above, with progressive elimination of micas and feldspars, to a quartz-tourmaline tourmalinite (some of which appear to be intrusive - products of extreme fractionation, such as the dyke at Roche Rock [SW992594] and the tourmalinite at Porth Ledden [SW354320] near Cape Cornwall).
Examples include rocks such as Luxullianite and Trevalganite.
Boron (and hence, tourmaline) has played a major part in the transport of metals during the high temperature phases of mineralisation (Charoy, 1982) and is a common constituent of main stage Sn lodes (Farmer, 1991) at depth (e.g., South Crofty Mine).
