... altered to carbonate and phyllosilicates, but these reactions were nearly isochemical. Structurally controlled hydrothermal graphite in the HMSZ occurs in microshears (up to 3 wt%, above background <0.2 wt%). Alteration in the Rise & Shine Shear Zone (RSSZ) was accompanied by addition of abundant...

Summary of Sb concentrations in the OSB. (a) Antimony concentrations in host rocks of differing metamorphic grade (after Pitcairn et al. 2006), and Sb contents of Macraes arsenopyrite (Petrie et al. 2005), Macraes mineralized rock (Craw 2002), and Sb contents of mineralized rocks in the Rise &amp; Shine Shear Zone (Cox et al. 2006). (b) Relationships between As and Sb in host metaturbidites (after Pitcairn et al. 2006), variably mineralized rocks at Macraes (Craw 2002), Rise &amp; Shine Shear Zone (Cox et al. 2006), and the Miocene orogenic veins (Fig. 5D; MacKenzie et al. 2007).
