Interpretation of Macroscopic Fold Structures in the Willyama Supergroup of
the Thackaringa Area, Broken Hill, N.S.W.
I.L. Willis
Abstract. The present complex distribution of lithological and stratigraphic units in the
Thackeringa area is due mainly to the formation of macroscopic interference structures during
multiple deformation. Three main generations of macroscopic folds are recognized in the area:
F1, F2, F3, with axial plane schistosities S1, S2 S3. These correspond with identical D1, D2 and D3
structures recognized by others elsewhere in the Broken Hill Block, indicting that there are no
substantial differences in structural evolution between the south-west and the north and central,
Broken Hill Block. A fourth generation (F4) macroscopic fold may represent a localized
structural event in the study area.
The lobate and dome-and-basin macroscopic interference pattern in the south Thackaringa
district is interpreted to have formed mainly by interaction of F1/F2 and F2/F3 folds. This open
interference pattern, with easterly-trending F2 fold axial plane traces, is unusual within the
Broken Hill Block. It is speculated that these easterly trends may have been to some extent
controlled or influenced by the adjacent Thackeringa-Pinnacles Schist Zone.

Chiral Discriminations and Molecular Propellers
Robert S. Vagg
[Presidential Address, 1984]
Abstract. The nature of molecular chirality and the control of discriminatory interactions
between chiral molecules are discussed in general with some emphasis on tetrahedral and
octahedral stereochemistries. In particular recent studies on a series of ternary ruthenium(II)diimine complexes with optically active α-amino acids which contain both of these
stereochemistries as chiral centres is reviewed. These systems are photo-labile and equilibrate on
irradiation with visible light so as to reflect their equilibrium constants chiral discrimination
energies between diastereoisomeric pairs. These energetic results are used to demonstrate the
various discriminatory effects of different substituents on the amine-nitrogen and α-carbon
atoms of the amino acids. Examples are given also of steroselective control of reactions at the
coordinated amino acid ligands.

Oligocene and Miocene Volcanic Rocks and Quartzose Sediments of the
Southern Tablelands, New South Wales: Definitions of Stratigraphic Units
Paul Bishop
Abstract. Tertiary volcanic rocks and associated quartzose sediments in the GoulburnCrookwell area of N.S.W. have been important in determining the Cainozoic history of this
portion of the Southeast Australian Highlands. Six units, the Bevendale Basalt, Hollymount
Formation, Wheeo Basalt, Divide Basalt, Bannister Basalt and Pomeroy Basalt, are defined in
order to aid discussion of the evolution of the area.

Introduction. In recent years the Royal Society of New South Wales has received an increasing
flow of requests for information about past members and enquiries as to whether a person was a
member at some time. These enquiries have come from members of the Society as well as from
non-members and outside organisations. Approximately two-thirds of the enquiries are known
or appear to be connected with genealogical research (which has recently achieved amazing
popularity). The other one-third of enquiries arises from various research projects in the the
history of Australian science and technology.
The lack of any co-ordinated membership lists for the Royal's predecessor societies, which
operated iin the middle of the nineteenth century, considerably impeded answering enquiries
relating to that period. To rectify the deficiency seemed imperative; impetus was added by the
preparations in hand to ensure an appropriate place for science in the forthcoming Bicentenary
celebrations.
We therefore undertook the compilation of as complete a list of members of the Royal Society
of New South Wales' two main antecedents as could be managed after the lapse of one and a
quarter centuries. Mere compilation of a list of names would have been relatively straightforward, but would not have answered such obvious questions as: what kind of work did men
(for they were all men) do?; how old were they?; what strands of colonial society did they
represent?, and so on. Thus we hoped to gain some appreciation of the human aspects of
scientific endeavour in nineteenth century Australia, and of lay awareness of and reaction to such
activity. Our list in its final form, with brief biographical data attached, proved to be of such
length that we felt is was best to be published in two parts in order not to take up too much
space in any one issue of the Society's Journal. In Part II we complete our list and append some
brief analyses to suggest answers to the question posed above.
