May 15, 2020· Tourmaline sampling site MA08 (S 28 50.590′ E 120 00.020′) consists of a multi-textural assemblage of three contrasting types of tourmaline-bearing rock. The first type is a major, 3x6 meter elongate-along-strike massive hydrothermally-derived intrusion of quartz-tourmaline rock consisting of approximately 25% tourmaline (50–400 μm crystals) and 75% quartz, cross-cut by many quartz veins.
