12. Basar (Anamesite). 
Map No. Re 28. 
Hardie’s Hill, near Crisis G. M. 
Oo., Durham Lead. 4 sheet 63 
S.E. 
Color brownish-grey : contains minute 
crystals of augite, olivine and triclinic 
felspar. 
13, Basatt (Anamesite), 
Map No. Rb 8. 
Section 37, Spring Plains. } sheet 
13 N.E. 
Of a bluish-grey color, and has a 
minutely vesicular appearance, caused 
by the open and irregular aggregation of 
its constituents, producing a roughness 
of surface where broken, It contains 
minute crystals of specular iron, having 
a blue tarnish, and cavities coated with 
carbonate of lime, running in bands, and 
hyalite. 
14. Basatt (Anamesite). 
Map No. Ra 101. 
Farmers’ Arms, Carisbrook road. 
i sheet 52 N.E. 
Of a brownish-grey color; finely 
vesicular, 
15. Basar (Dolerite). 
Map No. Ra 41. 
Lot 76, Carlsruhe, 4 sheet 9 N.E. 
Color greyish-brown, very dense and 
close-grained, and possessing a marked 
crystalline texture ; rich in olivine. 
16. Basatt (Anamesite). 
Wickliffe. 
Color brownish-grey, with an open 
porous sub-crystalline texture, 
giving the rock the appearance of being 
minutely vesicular. 
17. Basarrt (Anamesite). 
Map No. Rb 110. 
Section 106, Redesdale. 4 sheet 
13 N.E. 
Color grey: magnetic, with polarity; 
is dense and contains olivine. 
18. BASALT. Map No. Rc 5. 
Leigh River. } sheet 64 N.E. 
Color dark grey; texture close- 
grained: contains a little olivine, and is 
suitablefor building purposes. Specimen 
obtained from the lower flow. 
19. BASALT. Map No. Ra 105. 
Moolort. 4 sheet 52 N.E. 
Color greyish-brown; slightly vesi- 
cular, and containing triclinic felspar 
and small black grains, resembling 
augite and hematite. A good building 
stone. 
20. BASALT. 
Jim Crow Creek, Yandoit. } sheet 
15 S.E. ta 
Color bluish-grey; texture very 
dense, almost pisolitic, with an uneven 
and hackly fracture ; specimen obtained 
from the second layer near the termina- 
tion of the lower flow. On exposure it 
crumbles to a gravel. 
21. Basat (Lava). 
Mount Franklin. 4 sheet 15 S.E. 
Color dark ash-grey, minutely vesi- 
cular, earthy; fracture uneven, ap- 
proaching to hackly : contains a little 
olivine and oligoclase. 
‘ 
Note—* The basaltic lava streams of the country surrounding 
Mount Franklin and Franklinford are of two different ages. 
The older 
is antecedent to, and has been denuded during the formation of the pre- 
sent main drainage channels, and now forms detached patches, capping 
isolated hills or long narrow stretches on the tops of ranges. ‘The more 
recent streams have poured into the present valleys, and in their gradual 
descent from high points of eruption, appear, in some cases, to have 
covered the post pliocene, as well as the older and newer pliocene gold 
drifts (Jim Crow Creek and Mount Franklin streams). Only where 
they have acted as natural bars to, or lie in the line of the drainage from 
high levels, they are, in their turn, covered by recent alluvium (patch 
near Yandoit swamp, Franklinford, &.). As regards lithological 
character, the two flows present no marked difference.”—(Note, 4 sheet 
15 S.E.)
