title: Changes in Quality and Volatile Compounds of ‘Ready-To-Eat’ Kiwifruit with Transcriptome Insights

description: The developmental processes leading to the “ready to eat” ripening stage in kiwifruit differs by variety. In the present study, the effects of exogenous ethylene on quality and volatile compounds, as well as ripening-related gene expression, of red-fleshed kiwifruit cultivars (<i>Actinidia chinensis</i> cv. “Hongyang” and “Qihong”) were investigated. For postharvest ripening, uniform-sized fruits free from physical defects were treated with exogenous ethylene at 100 μL L<sup>−1</sup> for 3 days at 25°C. At the “ready to eat” stage, soluble solids content was increased; however, firmness and titratable acidity decreased clearly in both cultivars. A total of 28 volatile compounds were identified including, 10 aldehydes & amines, 7 alcohols, and 11 esters. The ethanol and methyl butanoate showed strong associations with the ethylene treatment in both cultivars. In addition, results indicated that the “ready to eat” stage in red-fleshed kiwifruit could be distinguished by hexanal in “Hongyang,” and by both hexanal and (E)-2-hexenal in “Qihong.” Transcriptome analysis identified 121 and 1813 unigenes that were differentially expressed in the control 3-day and ethylene 3-day treatments vs. at harvest, respectively, in “Hongyang.” In “Qihong,” a total of 45 and 1136 unigenes were differentially expressed in the same comparison. Among these, genes involved in ethylene biosynthesis, cell wall degradation, and volatile emission, such as ACO, β-gal, PL, and Alcohol dehydrogenase, were significantly upregulated by ethylene treatment, which contributes to “ready to eat” quality of both kiwifruit cultivars.

title: Characterisation of clay-hosted rare-earth element deposits in Australia: mineralogy, geochemistry and metallurgy

description: Australia hosts over 90 clay-hosted rare-earth element (REE) projects, yet research on the mineralogy and geochemistry of these deposits is limited compared with the well-studied ionic clay-hosted deposits in South China. This study presents scanning electron microscopy (SEM), X-ray diffraction (XRD), geochemical analyses (four-acid digest, weak-acid digest and flux fusion) and ionic-leach tests on regolith samples from nine clay-hosted REE projects in Australia to understand the deportment of REEs in the regolith. Most Australian clay-hosted deposits are non-ionic residual REE deposits. Residual monazite and bastnäsite as well as secondary rhabdophane and bastnäsite are the main REE minerals identified and host most of the REEs. The ionic REE proportion of Australian clay-hosted deposits in this study, determined <i>via</i> ammonium sulfate leach tests at pH 4, predominantly ranges from 0–3%, in contrast to deposits in South China with leach recoveries of ∼40–60%. No Australian deposits have a heavy REE (HREE) proportion of &gt;50%, whereas multiple deposits in South China do. The heavy rare-earth oxide (HREO) proportion of the studied Australian projects is ∼7–32%, and the magnet rare-earth oxide (MREO, Pr + Nd + Tb + Dy oxides) proportion is ∼21–25%. Analysing samples by different acid digestion methods quantified the effectiveness of each digestion technique. Weak-acid digest only recovered ∼73–90% of all REEs compared with the flux fusion total digest. The poor correlation of ionic-leach test recovery with weak-acid digest recovery in this study suggests that weak-acid digest recovery is not a reliable proxy for the ionic proportion of clay-hosted REE mineralisation. Weak-acid digest resulted in REE fractionation with preferential Nd–Gd recovery relative to La–Ce, owing to the different REE budgets and solubilities of REE phosphates. Four-acid digest is a near-total digest and recovered 90–97% of all REEs in clay-hosted REE deposits, with only minor REE fractionation. While some studied samples in some deposits have promising HREE enrichment or ionic portions, focus should lie on (1) targeting regolith profiles overlying HREE-rich source rocks in similar geomorphological settings as ionic clay-hosted REE deposits in South China or (2) refining processing pathways for non-ionic REE deposits. Ionic proportion is typically 0–3% across nine projects. High proportion of rhabdophane, monazite and bastnäsite. No significant HREE enrichment compared with South China. Mafic bedrocks potentially more prospective for HREE than granite in Australia.

title: Origin and HFSE enrichment potential of a Late Cretaceous basalt to peralkaline rhyolite suite in central Queensland, Australia

description: Peralkaline magmatic systems can host significant enrichment in high-field-strength elements (HFSE) (<i>e.g.</i> HREE, Zr, Nb, Ta), potentially yielding large-tonnage resources. Primary enrichment is interpreted to result from low-degree melting of a metasomatised mantle source followed by extensive fractional crystallisation. Secondary processes may modify resource potential, but primary magmatic enrichment remains critical, highlighting the importance of investigating these systems from source and tectonic setting through to emplacement. To understand controls on HFSE enrichment, we combined field mapping, petrography, geochemistry, isotopic analysis and geochronology to investigate an alkali basalt to peralkaline rhyolite suite in central Queensland consisting of the Alton Downs Basalt and Mount Hedlow Trachyte. The suite comprises a widespread magmatic field of basaltic lava flows, shallow mafic intrusions and felsic cryptodomes emplaced contemporaneously in the Late Cretaceous at <i>ca</i> 77 Ma. Geochemical trends and restricted isotopic compositions suggest derivation from a common mafic parent magma with minimal crustal assimilation. Fractionation progressed through plagioclase- to alkali feldspar-dominated assemblages, producing felsic endmembers evolving towards relative HFSE enrichment and agpaitic indicators (<i>e.g.</i> aenigmatite), or less HFSE enrichment and miaskitic assemblages (<i>e.g.</i> zircon, monazite). Sm–Nd isotopic compositions (<sub>Ɛ</sub>Nd<sub>(77Ma)</sub> = 6.07 to 7.34) indicate a depleted mantle source distinct from younger, plume-related elements of the Eastern Australia Volcanic Province. Trace-element enrichment in the most primitive basalts relative to MORB is consistent with a continental rift setting, which may ultimately relate to northward propagation of Gondwana breakup and development of failed rifts along the Queensland margin. Felsic rocks did not reach the extreme degrees of fractionation interpreted for more strongly HFSE-enriched suites in central Queensland (<i>e.g.</i> southern Peak Range Volcanics), and this may be the main limiting factor resulting in modest HFSE content. More fractionated bodies may exist at depth and would be more prospective. The Alton Downs Basalt and Mount Hedlow Trachyte were emplaced contemporaneously as an alkali basalt to peralkaline rhyolite suite at <i>ca</i> 77 Ma. These units form a widespread magmatic field of basaltic flows, shallow mafic intrusions and felsic cryptodomes, rather than a central volcano. Magma differentiation followed two evolutionary paths, influencing accessory phase mineralogy and HFSE content that was ultimately limited by the degree of fractionation achieved. Emplacement occurred in a failed continental rift during northward propagation of Gondwana breakup.
