Flow overlying hyaloclastites & sub basaltic sediments. Total uncertainty of precision of
age thought to be <4% at 95% confidence level


Flow overlying entrail breccias. Total uncertainty of precision of age thought to be <4% at
95% confidence level. Locality plots in Great Lake due to low water levels at time of
sampling.

Thick lowest flow. Total uncertainty of precision of age thought to be <4% at 95%

From letter by Dr. C. Brooks to Tas. Dept of Mines, 14th June 1971. No analytical data
given. Rb-Sr age 103 ± 23. Coordinates approximate only.



Sutherland & Wellman 1986 imply that error is ± 0.3 Ma (unknown error interval)



Minimum age. Error interval not stated in Tedford et al. 1975



Error interval not stated in Sutherand et al. 2002a. Although the locality is west of 144°, it
is classed as Zone 55


Base of flow at 420-460 m. Contains mantle xenoliths.

From a scree deposit on the Kellevie-Bream Creek road, obviously not transported very far
according to Baillie 1987

Age of volcanism is thought to be 47 Ma as the dates agree to within experimental error
and alluvial zircons associated with the basalts (Yim et al. 1985) give fission track dates
that agree to within experimental error

River, base at 380 to 500 m. River elevation 210 m

Age originally published on map reference. Analytical details obtained from letter from
AMDEL to Tasmanian Geological Survey dated 29th April 1990.

Age originally published on map reference. Analytical details obtained from letter from
AMDEL to Tasmanian Geological Survey dated 29th April 1990.

Sample is from Location 21 of Jennings & Sutherland 1969, and is described as a biotite-
augite-hornblende spessartite

Presented in poster but did not appear in abstract (Zwingmann et al. 2004).



Everard et al. 2004 list rad 40 Ar as 4.720 x 10e-3 mol/g, but this appears in error, as
samples with similar ages have ~4 x 10e-10, 7 orders of magnitude less.
Age of 23.6 Ma originally mentioned by Sutherland et al. 1973 with no analytical or location
data. Lat/long given by Sutherland & Wellman 1983 is inaccurate. Sample from lower flow
near river level, overlain by tholeiite. Contains mantle xenoliths.

Unpublished data, Zwingmann & Everard. Sample from beach boulders derived from top
flow in cliff section, overlying lower flow of tholeiitic basalt. Contains mantle xenoliths.




Contains mantle xenoliths.




Sample is from beach boulders

Base of upper flow at 540-560 m, overlying lower flow of nepheline hawaiite. Area
incorrectly mapped as Jurassic dolerite on Oatlands 50k map.




Presence of vesicles & the absence of thermal metamorphism in the underlying rocks
suggest this is a flow

Sample from the lower part of a basalt & terrestrial sedimentary sequence. AGD 66 lat/long
in Sutherland & Wellman 1986 does not fit with geological map or locality description (error
~700m).

Contains mantle lherzolite xenoliths

Sample is from the road cutting 50 m north of the Bass Highway on road C713. Moriarty
Basalt. Rock type is (calcic) nepheline hawaiite according to GS Tas data
Sample from behind timber yards on S side of monolith. Goto & McPhie 1996 describe
rock as basanite forming a laccolith. J. Everard Geol Survey Tas written comm 2007
describes sample as nepheline hawaiite.
Green Hills Volcanics. Sample is from the curved colonnades near the base of the pile at
the northern end of Godfreys beach
Location 42°48.6' 147°19.8' (AGD 66) supplied by F.L. Sutherand written comm 2007 Tuff
overlies olivine nephelinite flow, and is capped by a hawaiite flow.


Jericho plug. At 400 m elevation, inferred feeder for petrologically similar flow filling the
palaeovalley of Rose Hill Creek at 420-500 m, 2 km to the west

Contains mantle xenoliths. Longitude given in Sutherland 1989 is incorrect (by one
minute?)




From top flow, adjacent to volcanic centre. Lat/long in Sutherland & Wellman 1986 is
inaccurate and plots ~1.7 km S of locality.

Everard et al. in press not sighted, information from J. Everard Tas Geol Survey written
comm 2007

Locality now named Cassidys Creek. Coordinates from Sutherland et al. 1996a; latitude in
Sutherland & Wellman 1986 is inaccurate by ~6.6km.

Note that according to Sutherland et al. 1996a, this sample was collected only ~ 50m south
of SC1




Contains mantle xenocrysts.



Locality misnamed in original reference.


Sample possibly from the Beehive plug (495840mE 5330702mN), 1.2 km to NW. Latitude
provided by Sutherland & Wellman 1986 corresponds to The Haystack, but longitude to
The Beehive.

Sample is from 177 m thick unlateritised basanite fill, which overlies nephelinitic
pyroclastics. Contains mantle lherzolite xenoliths. Coordinates almost certainly inaccurate
and locality misspelt in original reference.




Macphail & Hill 1994 provide a sketch map for locality

Data provided by J. Everard, Geol Survey Tas, written comm 2007 Unpublished data of
A.V. Brown. Analytical details obtained from letter from AMDEL to Tasmanian Geological
Survey dated 29th April 1990.
Sample is from Location 9 of Jennings & Sutherand 1969




Date considered "anomalous" by Brown 1977 and omitted by Brown 1982. AMDEL
considered that the analytical error estimate (± 1Ma) may be too conservative.

Contains mantle lherzolite xenoliths
