Notes: Rock type: AD = altered dacite, BR = breccia, GD = green dacite. Alteration type: Sil = silicified, GSG = green silica-clay. * = ignited for 6 hr at 600C and then for 4 hr at 1050C. LOI = loss on ignition. Total sulfur and post-LOI for the ICP-AES samples are reported. LOI was conducted at 1050C for 4 hr. BD = below detection, ND = not determined, NCD = no curated depth.
