The immunoglobulin supergene family members have been shown to be involved in cell-cell recognition and interaction during cell growth and differentiation. Neural cell adhesion molecule, myelin-associated glycoprotein, and carcinoembryonic antigen (CEA) are immunoglobulin supergene family members which can mediate cell adhesion. We show here that nonspecific cross-reacting antigen (NCA), a clos...

The Mt Weld lanthanide deposit in central Western Australia is considered to be one of the largest high grade deposits known in the world, first reported as a carbonate and phosphate rich ultramafic silicate intrusion that contained a resource of the Lanthanide series [1]. It has been dated between 1.6 – 2.0 billion years, where the formation of a carbonate layer in the cooling melt created a p...

Gibbsite both invests and replaces crocoite in late supergene ores of the Dundas district, Tasmania. The laser Raman spectrum of the gibbsite shows strong, well-developed v-OH stretching bands at about 3370, 3440, 3525, 3620 cm-I, confirming its identity. Crocoite gives bands at 840 em-Iv!, 853 and 825 cm-l v3, 348 cm-l v 2, 400, 377, 358, 338 and 326 cm-l v 4, and at 179,135, and 118 em-I, cor...

Traits of interest to evolutionary biologists often have complex genetic architectures, the nature of which can confound traditional experimental study at single levels of analysis. In the fire ant Solenopsis invicta, the presence of a Mendelian 'supergene' is both necessary and sufficient to induce a shift in a fundamental property of social organization, from single-queen (monogyne) to multip...

The Hamersley Basin in Western Australia is one of the world's largest iron ore-producing regions, hosting two types ore banded formations: high-grade martite-microplaty haematite and supergene martite-goethite ores. With ores almost entirely mined last decade, have more recently become dominant resource interest. Consequently, understanding genesis these deposits a critical step for exploratio...
