摘要:AbstractGenetic sequence data allows for the identification of previously imperceptible cryptic species. Cryptic species are common in algae that have few morphologically distinguishable features. Identifying cryptic species with asexual life cycles requires consideration of whet...

摘要:Isolueshite, a cubic complex oxide with the formula NaNbO3, occurs as euhedral crystals 0.4–0.7 mm in size in calcite carbonatite, Kovdor ultrabasic-alkaline complex (Kola, Russia). Average composition of isolueshite, based on 40 analyses by wavelength-dispersive electronmic...

摘要:The crystal structure of duftite, PbCu(AsO4)(OH), has been re-evaluated on the basis of X-ray diffraction data from a single crystal from Grube Clara, Germany. Duftite is orthorhombic with a = 7.7668(4), b = 9.2005(5), c = 5.9878(3) Å; V = 427.88(4)Å3, non-centrosymmetric sp...

摘要:The Aqkand epithermal base metal deposit, located in the Tarom-Hashtjin metallogenic belt (THMB) of northwest Iran, is hosted by Eocene andesitic basalt lavas. Mineralization at Aqkand occurs as Cu-bearing quartz-fluorite breccia veins, and vug infill with comb, colloform, c...

摘要:Eleven natural crystals of Cr-bearing spinels containing Cr 0.1–1.5 and total iron 0.2–1.0 atoms per formula unit, have been studied by X-ray single crystal diffraction at ambient conditions and after heating at 600°C for 7 and 28 days in order to verify if they suffere...

摘要:The objectives of the present study were (1) to quantify the vertical distribution of the sediment bulk density (SBD), the sediment organic carbon (SOC) concentration, and the SOC density in the five northern lakes of Egypt (Bardawil, Manzala, Burullus, Edku and Mariut); (2)...

摘要:The upper Miocene locality of Mahmutgazi in Western Turkey was excavated in the 70s by a German team, but most of its large mammals had never been studied. The collection housed in the Staatliches Museum für Naturkunde, Karlsruhe, contains, besides previously published group...
