On Carnotite and an associated mineral complex from South Australia1
Published online by Cambridge University Press: 14 March 2018
Extract
This paper gives the results of an investigation at the Imperial Institute of a carnotite-bearing specimen received from South Australia.
The material represented by the specimen is described by Mr. H. Y. L. Brown, Government Geologist of South Australia, as occurring about 2 miles SSW. of Teesdale's dam and about 20 miles ESE. of Olary railway station. He remarks : ‘The ore occurs as yellow and greenish-yellow incrustations and powder on the faces, joints, and cavities of a lode formation, which consists of magnetic titaniferous iron, magnetite, &c., and quartz in association with black mica (biotite) . . . . . . The outcrops traverse metamorphic gneissic micaceous granite and granite schist, into which dykes of granite and diorite have been intruded.’

Page 280 note 1 The occurrence of the carnotite as platy growths in these cavities accounts for the good crystals obtained by partial crushing and magnetic separation.
Page 280 note 2 In making the above analysis, the estimation of alkalis was inadvertently omitted ; an examination of a separate fragment showed that alkalis were present, perhaps to the extent of a few tenths per cent.
