AbstractSoda-rich pyroxenes in felsic rocks from the Warrumbungle Volcano, central New South Wales, contain up to 14.5 wt. % ZrO2, which is more than double the previously reported maximum ZrO2 in pyroxene. Zr is believed to enter aegirine as the component Na(Fe2+,Mn,Mg)0.5Zr0.5Si2O6 via the coupled substitution: (Fe2+,Mn,Mg)VI+ZrVI = 2(Fe3+)VI. This component exceeds 50 mol. % in some analyses.Pronounced pyroxene Zr-enrichment is restricted to rocks in which sodic amphibole is the major ferromagnesian mineral, with pyroxene only a minor late-stage phase. The Zr-rich pyroxenes resulted from a combination of host lava peralkalinity, low oxygen fugacity, rapid disequilibrium crystallization and low mobility of the Zr ion. These factors collectively led to the development of interstitial Zr-enriched microdomains in the felsic hosts during their final stages of crystallization.

Proportionality Relationship

SummaryRetrograde metamorphism of gneisses and pegmatites leads in part to the destruction of feldspar and its replacement by late-stage lobate myrmekite and muscovite. Reactions promoted by retrogression suggest a range in volume of quartz production that may supplement that developed by exsolution and lead to deviations from the strict proportionality relationship suggested by previous workers. There is no need, however, to propose that quartz in myrmekite originates by constriction of pre-existing quartz within exsolved albite.

17043 Background: Ethnicity may influence both the incidence and prognosis of breast cancer. We have conducted an analysis to determine if women from non-English speaking backgrounds (NESB) living in New South Wales (NSW), Australia, present with later stage breast cancer compared to women from English speaking backgrounds (ESB); and to determine whether there is an impact on their survival. Methods: Data from the NSW Cancer Registry (1980 to 2004) was used to identify women with their first presentation of breast cancer. Stage of breast cancer was classified as early (insitu or localized) versus late (regional nodal or distant metastatic spread) according to registry definitions. Country of birth was used as a surrogate for language status. Stage at diagnosis was compared between ESB versus NESB women. Logistic regression was used to determine the odds of late stage disease and Cox regression to determine survival outcomes Results: 60,676 of 75,583 cases were considered suitable for analysis. Of these 16.64% were NESB. Accounting for potential confounding variables, NESB women were more likely to have late stage disease than ESB women (OR= 1.12; 95% CI, 1.07 to 1.17). Analysis by geographical region of birth revealed women born in Middle Eastern region were most likely to have late stage disease at presentation (OR 1.41; 95% CI, 1.25 to 1.60). In multivariable analysis of all-cause mortality NESB women had a superior overall survival (HR 0.90; 95% CI 0.87 to 0.94) compared to ESB women, however, there was no difference in breast cancer specific survival between these groups by univariate analysis (logrank p=0.46). Conclusions: In New South Wales, Australia, NESB women have a delayed presentation with breast cancer as indicted by more advanced stage. However, stage-adjusted, breast cancer specific survival in NESB women is similar to the ESB women. Further studies are required to determine the reasons for delayed detection for NESB women. No significant financial relationships to disclose.

Oceanic Plagiogranite

SummaryPlagiogranites occur mainly as intrusive bodies and tectonic inclusions within mafic and ultramafic members of the Coolac ophiolite suite. Quartz diorites and trondhjemites appear to represent localized late-stage felsic differentiates of subalkaline tholeiitic magma, with their formation dominantly controlled by fractionation of hornblende and plagioclase. Albitites are interpreted as altered equivalents of quartz diorites and trondhjemites. Chemical data, while emphasizing the similarity of these rocks to ‘oceanic plagiogranite', also indicate that variation in the latter may be broader than previously defined. The Coolac rocks show less marked Fe-enrichment, higher Ni and Cr, and lower Y and Zr than many ophiolitic plagiogranites. These data are consistent with weak calc-alkaline tendencies demonstrated in the Coolac ophiolite suite.

Australian pelicans (Pelecanus conspicillatus) were studied in colonies at 2 lakes in New South Wales. Adults regurgitated food for the young. Those up to 2 weeks old took liquid food from inside the tip of the adult's upper beak. Older ones took solid food from the adult's gullet, to age of about 3.5 months. After being fed, the young had convulsions lasting about 1 min; that did not happen after a second feeding immediately after the convulsion. Where there were 2 young of different sizes, only the larger convulsed, and sometimes the smaller was prevented from feeding and died of starvation. The survivor continued to have convulsions after feeding, as did single young, when there was no competition for food. Food was mainly fish; the most abundant fish was goldfish (Carassius auratus); a minor item was perch (Perca fluviatilis). Fish were 60 to 247 mm long and weighed 17 to 320 g. Crustaceans were less important and included freshwater crayfish (Cherax destructor) and shrimp (Macrobrachius sp.).

Degree of host tissue response to monogenean (Lamellodiscus acanthopagri, L. major, L. squamosus, Haliotrema spariensis, Polylabroides multispinosus) and copepod (Ergasilus sp., Lernanthropus atrox, Alella macrotrachelus) parasites on the gills of Acanthopagrus australis varied with developmental stage and among species. The histophagous ancyrocephalines L. acanthopagri and L. squamosus and the sanguinivorous polyopisthocotylean P. multispinosus elicited no host response. In contrast, phylogenetic relatives of the former two species, L. major and H. spariensis, were associated with extensive hyperplasia of the filament. Among the copepods, Ergasilus sp. elicited a minor response. However, larval, subadult, and adult A. macrotrachelus were associated with increasing extents of filament alteration. Similarly, adult L. atrox were associated with massive hyperplasia which often included adjacent filaments. The observed variability in tissue response is discussed in terms of parasite attachment, mobility, and feeding strategies.

Thick Deposit

AbstractA thick deposit of flint clay in the Permian I llawarra Coal Measures of the southern part of the Sydney Basin, New South Wales, is described. The flint clays which have affinities with those of the Pennsylvanian of North America and with the kaolin coal tonsteins of the Westphalian, are associated with red-brown claystones that contain in addition to hematite, an abundance of a regular mixed layer clay mineral. Pyrophyllite generally forms a minor constituent only of the flint clays but in one part of the deposit it is more abundant than kaolinite. Although there are many puzzling aspects concerning the origin of the deposit, evidence suggests that the kaolinite and the pyrophyllite in the flint clays are detrital.
