Lithology and provenance of late Eocene - Oligocene sediments in eastern Taranaki Basin margin and implications for paleogeography [PDF]

, 2009
The latest Eocene and Oligocene was a time of marked paleoenvironmental change in Taranaki Basin, involving a transition from the accumulation of coal measures and inner shelf deposits to the development of upper bathyal environments. Up until the end of

Formation Age and its Geological Significance of Quartz Diorite from Cryptoexplosive Breccia in Dalucao Rare Earth Mine, Sichuan Province

Kuangchan zonghe liyong
To limit the diagenetic age of quartz diorite in the crypto-explosion breccia of the Dechang Dalucao in Sichuan Province, LA-ICP-MS zircon U-Pb chronology was carried out.

Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

Where the Mineral Kingdom Might Hide New Forms of Matter

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Mineralogy has traditionally classified matter primarily through local chemistry and diffraction symmetry. But some physically distinct states of matter differ neither principally in composition nor in obvious diffraction symmetry; they differ in how fluctuations behave over very large distances.

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

Journal of Applied Polymer Science, Volume 143, Issue 43, November 15, 2026.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Permian sedimentary sequence containing analcimolite and authigenic aegirine from the Boskovice Basin (Bohemian Massif, Czechia)

The Depositional Record, Volume 12, Issue 5, November 2026.
The Permian freshwater lacustrine sedimentary sequence rich in analcime, with unusual authigenic aegirine and NaFe3+ clinopyroxene. Product of ashfall directly linked with fossil accumulation (Konzentrat‐Lagerstätte). Abstract The Early Permian freshwater lacustrine sedimentary sequence in the vicinity of Bačov (Czechia) is world‐famous for its rich ...

Trace elements and melt inclusion in zircon within the Qunji porphyry Cu deposit: Application to the metallogenic potential of the reduced magma-hydrothermal system

Open Geosciences
The Qunji porphyry copper (Cu) deposit, located within the Awulale metallogenic belt (AMB) in the western Tianshan orogenic belt, exhibits distinct geochemical and mineralogical characteristics that have not been fully understood.
