BHD7	Sock Creek	0	13.6	Cy	PV	w		Df								Moderate to weak clay development due to weathering
BHD7	Sock Creek	41	44	Ab	PO	w	He	PV	t							Selective albitisation of feldspar pheno's
BHD7	Sock Creek	44	46.2	Se	Df	w										Weak matrix alteration
BHD7	Sock Creek	46.2	60.6	Ks	CL	w										Weak yellowing of clasts
BHD7	Sock Creek	67.8	75.6	Se	WP	w	Ks	CL	w							Vivid orange clast alteration in reen sericitic matrix
BHD7	Sock Creek	75.6	83	Se	PV	t										Minor sericite alteration only
BHD7	Sock Creek	83	89.5	Si	PV	w	Se	PV	t							Very weak silica+/-ser with hints of bleaching
BHD7	Sock Creek	89.5	97.8	Se	PV	t	Si	PV	t							
BHD7	Sock Creek	97.8	101.4	Si	PV	m	Ks	PV	w							Zone of bleaching - possibly around a small structure
BHD7	Sock Creek	101.4	123.9	Si	PV	t	Se	Df	t							Typical weakly altered lava and lava breccia_ minor bleached silicified zones also. Hint of carbonate in matrix.
BHD7	Sock Creek	123.9	140.6	Si	PV	s	Cb	VL	w	Cl	PO	t				Bleached ?dacitic lava with vesicle infil by carb + chl_ overprinted by silicification or bleaching
BHD7	Sock Creek	140.6	151.3	Si	PV	t	Se	Df	t	Cb	VL	w				Typical Dacitic alteration but with increased carbonate and bleaching across narrow ?basaltic unit.
BHD7	Sock Creek	151.3	175.9	Si	PV	s	Cb	SW	m	Cl	PO	t				Bleached dacitict lava sequence (2-3 units with slightly different alteration). Albite alteration gives distinctive orange colour in top 6m of interval. Also some narrow vein overprinting.
BHD7	Sock Creek	175.9	199.5	Se	Df	w	Si	PV	m	Cb	VL	t				Weakly altered except for 179-180.3 where strong ser-albite/Kspar zone around a small shear and vein occurs.  Minor infilling of vesicles by carbonate and chlorite - same with mafic pheno's.
BHD7	Sock Creek	199.5	207.3	Si	PV	s	Ks	Df	m	Cb	VF	m	Cl	WP	w	Apparent zone of silica-Kspar(or albite?) bleaching around a structure that has a small amount of dacitic material caught up in a structure which may also coincide with the base of a lava flow.
BHD7	Sock Creek	207.3	235.6	Si	PV	w	Se	Df	w							Very similar to the interval 175.9-199.5m
BHD7	Sock Creek	235.6	239.3	Si	PV	s	Ks	Df	m	Ab	PV	m	Cb	VF	m	Very similar to the interval 199.5-207.3m
BHD7	Sock Creek	239.3	241.8	Si	PT	m	Ab	VF	s	Se	CL	w	Cb	VF	w	Bizzare interval of brecciated blck shale/siltstone and dacite. Either end of this interval has strong silica-albite-carbonate ?vein fill which diminished to weakly altered black shale in the centre of the interval. Some cherty sediment (due to alteration) and common overprinting carb-sil veinlets.
BHD7	Sock Creek	241.8	274.5	Si	PV	w	Ab	CL	w	Cl	WP	t				Pervasively silicified (weakly) and albitised which gives an apparent autoclastic texture.  Essentially constant alteration throughout save for a zone of increased albite intensity at 260m plus 267 and 271-273m.
BHD7	Sock Creek	274.5	280.8	Si	PV	m	Se	WP	w	Cl	WP	w				Less strongly altered Rhyodacite.
BHD7	Sock Creek	280.8	284.2	Cy	SM	i	Se	WP	m							Fault gouge with mostly clay infill between bits of broken rhyodacite.
BHD7	Sock Creek	284.2	309.5	Si	PV	s	Se	Df	m	Cy	SW	w	Cl	WP	w	Broken Rhyodacite with minor clay filled gouges but zones of intense silicification.
BHD7	Sock Creek	309.5	334.9	Si	PV	s	Se	Df	m	Cl	VL	t				More massive rhyodacite with variable but occasionally intense silicification.
BHD7	Sock Creek	334.9	337.1	Si	PV	w	Cb	VL	w							Typical shale/siltstone with numerous veinlets.
BHD7	Sock Creek	337.1	339	Si	PV	i	Se	PV	s							Intense sil-ser altn of rhyodacite_ sheared in places.
BHD7	Sock Creek	339	363.6	Si	PV	w	Cb	VL	w							Typical shale/siltstone
