Origin of the Moon
A.E. Ringwood
The Clarke Memorial Lecture for 1969
1. Introduction. This lecture was delivered at a time when the only information available to me on lunar rocks consisted of preliminary chemical data obtained by the Lunar Sample Preliminary Examination Team (LSPET, 1969) and some preliminary investigations on the mineralogy and petrology of Apollo 11 samples which were being studied in Canberra. Preparation of this paper was inadvertently delayed, and a vast amount of detailed data on the lunar rocks has since been published, principally in Science Vol. 167, No.3918, 1970, and in the Proceedings of the Apollo 11 Lunar Science Conference, Vols. 1,2 and 3. In this paper I shall cover much the same ground as was covered in the Clarke Lecture, but will incorporate more recent chemical and petrological information where appropriate. Fortunately, most of the more general boundary conditions on which I based my discussion of the origin of the moon have been amply confirmed by the new data. This is a tribute to the excellence of the work carried out by the Lunar Sample Preliminary Examination Team.
2. Nature of Apollo 11 Crysalline Rocks (a) General Properties and Distribution Perhaps the single most important discovery of the Apollo 11 mission which landed in Mare Tranquilatus was that the crystalline samples returned were clearly identifiable as mafic igneous rocks closely related to basalts ...

Gorceixite-Goyazite in Kaolinitic Rocks of the Sydney Basin.
F.C Loughnan and C.R. Ward
Abstract. Occurrences of the phosphate mineral gorceixite-goyazite (Ba,Sr)Al2(PO4)2(OH)5, in a claystone from the Illawarra Coal Measures and in two dyke clays from the southern part of the Sydney Basin are described. The phosphate mineral is associated with abundant well-ordered kaolinite and minor amounts of anastase. The concentration of the phosphate mineral in parts of the claystone could be attributed to its high specific gravity compared with that of the associated kaolinite. However, no explanation can be given for the origin of the mineral in the dyke clays.

Internal Seiche Motions for One-dimensional Flow
D.J.Clarke
Abstract. The modes of osicillation for the internal waves at a density discontinuity are examined for a variable shaped basinUntitled 1. The flow is considered as one-dimensional, the equations of motion are linearized, and the rotation of the earth is neglected.
