Moraine

Ferrar Dolerite
Tholeiitic diabase sills intruded into Permian and Triassic strata; rare dikes. Meas-
ured sills as thick as 260m

( ]
: Fremouw Formation
Only lower part of formation present. Cyclic very light-colored quartzose sandstone

and greenish-gray mudstone. At Graphite Peak in Plunket Point quadrangle
sandstone contains labyrinthodont jawbone fragments, Thickness 100+ m

Buckley Formation

Cyclic light-colored crossbedded sandstone, carbonaceous shale and high-rank high
ash coal. Logs, stems and glossopterid leaves common. Sandstone beds normally
have erosion surfaces at base and shale fragments in lower part. Sandstone is
subarkosic to arkosic low in formation but volcanic fragments become abundant be-
tween 100 and 300m above base. Volcanic sandstone, commonly laumontized, dom-
inates upper part. Lower contact of formation marked by appearance of white
rounded quartz pebbles. Quartz pebbles occur at higher levels also. Thickness at
least 450m

Fairchild Formation
Light-colored massive subarkosic to arkosic sandstone with well-developed crossbed-
ding and parting lineation. Thickness 130-150 m

Mackellar Formation
Dark gray to black finely laminated to thinly bedded shale alternating with light gray
and greenish-gray very fine-grained thinly bedded subarkosic sandstone. Ripple
drift bedding widespread. Ripple marks and slump folds at many localities.

Thickness 70-90 m

Pagoda Formation
Grayish-green sandy tillite with boulders as much as 2 m across, interbedded with
tan or white quartzose sandstone and minor conglomerate, limestone and shale.
Locally basal tillite is very quartzose. Features on grooved surfaces beneath some
tillite beds indicate paleo-ice flow to southeast. Crossbedding common in sandstone.
Rare plant fragments. Thickness 130-180 m

Beacon Strata

DISCONFORMITY

Alexandra Formation
White to light brown medium- to coarse-grained well-sorted quartzose sandstane with
abundant crossbedding. Thin beds of black shale and gray fine-grained limestone
Ms in Holland Range. Thickness about 300m

Ida Granite
Aplitic quartz monzonite and granite. Intrudes Hope Granite at Mt. Ida and Granite
Pillars. Light gray (fresh), rusty brown (weathered); weathered rocks commonly
hematite stained. Texture fine- to medium-grained, locally porphyritic. Typically
consists of aplitic or hypidiomorphic-granular microcline, quartz, and unzoned or
slightly zoned albite or sodie oligoclase (Ang to An 17) with accessory biotite,
muscovite, apatite, epidote, hornblende, magnetite, sphene and zircon. Medium- to
coarse-grained, euhedral, grayish-blue phenocrysts of albite or sodic oligoclase may
be present. Myrmekite rare or absent. Includes pegmatite and aplite dikes in-
truding Hope Granite and Goldie Formation. Foliation, xenoliths and prominent
Jointing rare. Contacts of Ida and Hope Granites at Granite Pillars are inacces-
sible, but appear sharp. At Mt Ida the contact is diffuse, with several composi-
tionally intermediate phases separating the two units. Rb-Sr whole-rock isochron

Hope Granite

Brotite quartz monzonite, with minor granodiorite and granite. Intrudes Goldie For-
‘mation. Gray (fresh), rusty brown (weathered); hematite stained on weathered
surfaces. Medium- to coarse-grained, frequently porphyritic. Typically consists
of coarse to very coarse subhedral white to pink microcline phenocrysts in a hypi-
diomorphie- to xenomorphic-granular matrix of quartz, normally zoned calcie ol
goclase,andesine, or labradorite (Angi to Ang6), biotite and interstitial myrmekite,
with accessory apatite, hornblende, sphene and zircon. Dark xenoliths of biotite
schist and granofels, 2.cm to several meters across, locally abundant. Primary
foliation by alignment of prismatic microcline phenocrysts and elongate xenoliths
occurs locally, especially near pluton margins. Secondary foliation is absent.
Marginal contacts of Hope Granite plutons sharply abut indurated and conta
metamorphosed country rock. Biotite K-Ar dates 465 and 450 m.y. from Celebration
Pass. (McDougall and Grindley, 1965). Rb-Sr whole-rock isochron date 463-7 m.y.
(localities 1 to 6). (Gunner, 19714)

Granite Harbour Intrusives

Oea

Quartz diorite

Gray (fresh), dark brown (weathered). Mineralogy variable. Plagioclase, horn-
blende and/or biotite and (frequently) quartz essential. Plagioclase(Angs to Ango)
shows oscillatory zoning, overall more albitic toward periphery. Clinopyroxene,
hypersthene and K-feldspar accessory in some rocks. Xenoliths, probably meta-
sedimentary, abundant. Crops out as small stocks intruding Goldie Formation.
Relation to Hope and Ida Granites unknown. Tentatively included in Granite

L Harbour Intrusives

( f [a
Goldie Formation

Interbedded sandstone, siltstone, shale and minor conglomerate, Schist and slate
where metamorphosed. Arenites include principally metatitharenite, feldspathic
metalitharenite, sublitharenite, lithic arkose, subarkose. Principal detrital com-
ponents quartz; muscovite, mica schist, plagioclase, biotite, microcline, and lpcally
chert and granite, Sand-size grains are very fine to very coarse, very angular to
sub-round, poorly to very poorly sorted. Graded bedding common in arenites. Sole
marks occur locally. Tight to isoclinal folding about north-south trending axes
throughout. Fold axes plunge gently north or south. Spacing of fold axes com-
monly 100 to 500 m; axial surfaces vertical or steeply dipping. Slaty cleavage in
argillaceous beds near fold hinges. Weak metamorphism occurs throughout, with
ubiquitous conversion of clay matrix to sericite, and development of foliation paral-
lel to bedding in some areas. Higher metamorphic grades (hornblende-hornfels facies)
occur in vicinity of Granite Harbour Intrusive plutons; eg. at Ebony Ridge. Base
not exposed. Total thickness unknown. Rb-Sr whole-rock isochron date on com-
posite samples of 538-+28 my. probably due to isotopic homogenization of strontium

L L since deposition. (Gunner, 1971a)
