DESCRIPTION

Casing.

Andesite - dark green to dark grey

green in colour, fine grained, chloritic

and weakly carbonatized.This narrow unit is quite strongly

magnetic from the presence of numerous fine

blebs of exsolved magnetite. Very fine

traces of pyrite were also noted.

The core is cut by scattered, irregularstrongers of calcite.

Lower contact broken.

Broken contact to hornblende qabbro.The gabbro is medium to dark green in colourand medium to coarse grained with erratic

fine grained sections. For the most part,the gabbro is non-magnetic, only veryscattered sections show a weak magnetic

attraction. The gabbro is moderately car bonatized and cut by fairly numerous.irregular stringers of greyish to milkycalcite .

The gabbro is composed of abundantblocky to lath shaped phenocrysts of horn blende, and chlorite after hornblende set

in a matrix of chlorite and fine grained

feldspar (tiny lath shaped crystals) . The

feldspar also occurs in large (up to 2 cm)

patches, normally amorphous but locally

exhibiting a ,weak granophyric texture.

Chlorite is a common constituent pseudo-

mo rphic after hornblende and in the finer

grained matrix. Scattered, tiny blue

quartz (cordierite?) phenocrysts are also

seen throughout this unit.

The fine grained sections within the

gabbro are erratically distributed along

the length of this zone. Hornblende toghost phenocrysts of hornblende are commonwith the remaining core being very finegrained and chloritic. Although thereappears to be no direct relationship betweenthese units and the amount of calcitestringers, these finer grained sections aremuch more strongly carbonatized than theadjacent coarse gabbro.

The lower contact of the gabbro isgradational to andesitic lavas.

DESCRIPTION

Andesite - fine to medium grained, and

medium to dark green and grey green in

colour.Unlike the collar of the hole, this

unit is non-magnetic. The rock is chloritic

and variably carbonatized. Near the startof this andesitic zone there are scattered

coarser grained factions which appear

marginal in composition to the adjacent

gabbro. The odd black lath shaped crystal

of amphibole (?) plus an occasional meta

cryst of feldspar are seen in these coarser

grained portions.

The andesite is not as strongly car bonatized in the coarser grained horizons.

As elsewhere in the hole, the core is cut

by fairly numerous, irregular stringers

of calcite. Some very finely disseminated

pyrite was noted along the core.

Sharp contact at 46O to a zone ofporphyry. The rock is grey to brownishgrey in colour, hard, cherty, and carbona

tized. Ghost phenocrysts of feldspar andmetacrysts(?) of calcite are scattered alone

DESCRIPTION

1 foot of core is either lost or ground

Most of the better quartz veins are

isolated in the area 215-225. The widest

stringer is from 215.7 - 217.0. The

majority of the stringers are either un-

mineralized or carry only splashes of

pyrite. Two stringers, however, at 218.8

and 220.1-220.4, carry accessory sulphides -

the former contains splashes of pyrrhotiteand chalcopyrite at the margins while thelatter stringer is vuggy with alteredwallrock, graphite and some coarse patchesof pyrite-chalcopyrite.

One section, from 226.5 - 233, grades

darker in colour with increased chloriteand appears to be marginal in compositionto andesite.

Broken contact at 65O to a wide zoneof tuffs and coarser fraqmentals, generallyof dacitic composition.

Up to approximately 282, the rocks

are tuffaceous with numerous fragments up

to 1 cm in length. Most of the fragments

are stretched to lenticular shapes sub-

parallel to the schistosity- lineation at

6 0-7 O0 . Most variations in alteration

occur in zones of 1 to 3 metres, contacts

between altered units being gradational.

The grey green tuff member in this instanceis most strongly carbonatized, and appears

marginal in composition to andesite. Thecherty, grey to dark grey sections, on theother hand, are probably within a rhyoliticcomposition.

Around 282 metacrysts(?) of feldspar

are developed in the tuffs and there isless variation in the compositional range.Further, after 282, occasional larger, sub

rounded fragments up to 3 cm are notederratically along the core. All of thelarger fragments seen were of porphyry -grey to brownish grey with phenocrysts of

By 327, the amount of feldspar meta-

crysts present is almost negligible again.

From here to 350, the rock is a dacitic

tuff with occasional cherty and more

chloritic-carbonatized horizons. In

general, the rock grades darker green in

colour and carries less fragments towards

the contact with andesite at 350.

The most abundant fragment types notedacross this unit were cherty - pale green txcream coloured and greyish very fine grained

chert.The core is cut by occasional quartz

and calcite stringers, although they aremuch more widely separated than earlier inthe hole. Wider quartz stringers are notedat: 271.1-272.1 @ 10O ; 278.4-279.6 along

core, w. splashes of py cp and ZnS; and293.6-293.8 @ 20O .

DESCRIPTION

Fragments are very fine, lapilli sized

(averaae 1 mm) , and quite uniformly elongated

at 70O to the core axis.

Stringer content is almost negligible

in this unit, but all those seen (@ 354.8,

357.6, 359.1 and @ 364) carry splashes of

sulphides - sphalerite and pyrite. There

are also lenticular blebs of pyrite-

sphalerite scattered along the core in this

unit.

Gradational contact into dacite (torhyolite) tuffs. The rocks in this zone

are grey to arey areen in colour, fairlywell silicified and carbonatized.

Occasional fragments in the tuff areup to 3 cm across - the norm being a fewmm to a cm in lencrth. Most of the fragment:

are grey, fine drained and cherty.This unit is completely devoid of

stringers. Some finely disseminated

sulphides are seen across the unit - tinylenticular blebs of pyrrhotite and/or

pyrite. .END OF HOLE /lt^f(
